The M series of DC-DC (AC-DC) converters represents a
broad and flexible range of power supplies for use in ad-
vanced industrial electronic systems. Features include high
efficiency, reliability, low output voltage noise and excellent
dynamic response to load/line changes due to individual
regulation of each output.
The converter inputs are protected against surges and tran-
sients occuring at the source lines. An input over- and
undervoltage lock-out circuitry disables the outputs if the in-
put voltage is outside the specified range. Certain types in-
clude an inrush current limitation preventing circuit break-
ers and fuses from being damaged at switch-on.
agencies LGA (Germany) and UL (USA). The UL Mark for
Cana-da has been officially recognized be regulatory au-
thorities in provinces across Canada.
The case design allows operation at nominal load up to
71°C in a free air ambient temperature. If forced cooling is
provided, the ambient temperature may exceed 71°C but
the case temperature should remain below 95°C under all
conditions.
All outputs are open- and short-circuit proof and are pro-
tected against overvoltages by means of built-in suppressor
diodes. The outputs can be inhibited by a logic signal ap-
plied to the connector pin 2 (i). If the inhibit function is not
used pin 2 should be connected to pin 23 to enable the out-
puts.
A temperature sensor generates an inhibit signal which
disables the outputs if the case temperature TC exceeds the
limit. The outputs are automatically re-enabled when the
temperature drops below the limit.
LED indicators display the status of the converter and allow
visual monitoring of the system at any time.
Various options are available to adapt the converters to in-
dividual applications.
Full input to output, input to case, output to case and output
to output isolation is provided. The modules are designed
and built according to the international safety standard
IEC/EN 60950 and have been approved by the safety
The modules may either be plugged into 19 inch rack sys-
tems according to DIN 41494, or be chassis mounted.

Functional Description
mary switching transistor. This signal is fed back via a cou-
pling transformer.
The input voltage is fed via an input fuse, an input filter, a
rectifier 3 and an inrush current limiter 4 to the input capaci-
tor. This capacitor sources a single transistor forward con-
verter. Each output is powered by a separate secondary
winding of the main transformer. The resultant voltages are
rectified and their ripples smoothed by a power choke and
an output filter. The control logic senses the main output
voltage Uo1 and generates, with respect to the maximum
admissible output currents, the control signal for the pri-
The auxiliary outputs Uo2 and Uo3 are individually regulated
by means of secondary switching transistors. Each aux-
iliary output's current is sensed using a current transformer.
If one of the outputs is driven into current limit, the other out-
puts will reduce their output voltages as well because all
output currents are controlled by the same main control cir-
cuit.

Input Fuse
A fuse holder containing a slow-blow type fuse (Dimension:
5 × 20 mm) is mounted in the converter's back plate. The
fuse protects the module against severe defects. It may not
fully protect the module at input voltages exceeding
200 V DC. In applications where the converters operate at
DC source voltages above 200 V DC, an external fuse or a
circuit breaker at system level should be installed.

Input Under-/Overvoltage Lock-out
If the input voltage remains below 0.8 Ui min or exceeds
1.1Ui max (approx. values), an internally generated inhibit
signal disables the output(s). When checking this function
the absolute maximum input voltage rating Ui abs must be
carefully considered (see table: Input data). Between Ui min
and the undervoltage lock-out level the output voltage may
be below the value defined in table: Output data (see: Tech-
nical Information: Measuring and Testing).
Reverse Polarity
Reverse polarity at the input of AM, BM, CM, DM, FM and
CMZ, DMZ types will cause the fuse to blow. In EM, LM and
LMZ types a series diode will protect the module. A series
diode is not incorporated in AM, BM, CM, DM, FM and
CMZ, DMZ types to avoid unwanted power loss.
Inrush Current
Ii [A]
The CM, DM, EM, LM and CMZ, DMZ, LMZ (excluding FM)
modules incorporate an NTC resistor in the input circuitry
which (during the initial switch-on cycle) limits the peak in-
rush current to avoid damage to connectors and switching
devices. Subsequent switch-on cycles within a short inter-
val will cause an increase of the peak inrush current due to
the warming up of the NTC resistor. Refer also to: Option E
description.

Thermal Considerations
Thermal Protection
If a converter is located in free, quasi-stationary air (con-
vection cooling) at the indicated maximum ambient tem-
perature TA max (see table: Temperature specifications) and
is operated at its nominal input voltage and output power,
the temperature measured at the: Measuring point of case
temperature TC (see: Mechanical Data) will approach the
indicated value TC max after the warm-up phase. However,
the relationship between TA and TC depends heavily on the
conditions of operation and integration into a system. The
thermal conditions are influenced by input voltage, output
current, airflow and temperature of surrounding compo-
A temperature sensor generates an internal inhibit signal
which disables the outputs if the case temperature exceeds
TC max. The outputs are automatically re-enabled if the tem-
perature drops below this limit.
Output Protection
Each output is protected against overvoltages which could
occur due to a failure of the internal control circuit. Voltage
suppressor diodes (which under worst case condition may
become a short circuit) provide the required protection. The
suppressor diodes are not designed to withstand externally
applied overvoltages. Overload at any of the outputs will
cause a shut-down of all outputs. A red LED indicates the
overload condition of the respective output.
nents and surfaces. TA max is therefore, contrary to TC max
,
an indicative value only.
Caution: The installer must ensure that under all operat-
ing conditions TC remains within the limits stated in the
table: Temperature specifications.
Parallel and Series Connection
Main outputs of equal nominal voltage can be connected in
parallel. It is important to assure that the main output of a
multiple output module is forced to supply a minimum cur-
rent of 0.1 A to enable correct operation of its own auxiliary
outputs.
Notes: Sufficient forced cooling or an additional heat sink
allows TA to be higher than 71°C (e.g. 85°C) if TC max is not
exceeded.
For -7 or -9 units at an ambient temperature TA of 85°C with
only convection cooling, the maximum permissible current
for each output is approx. 50% of its nominal value as per
figure.
In parallel operation, one or more of the main outputs may
operate continuously in current limitation which will cause
an increase in case temperature. Consequently, a reduction
of the max. ambient temperature by 10 K is recommended.
Io/Io nom
Main or auxiliary outputs can be connected in series with
any other output of the same or another module. In series
connection, the maximum output current is limited by the
lowest current limit. Output ripple and regulation values are
added. Connection wiring should be kept as short as possi-
ble.

If output terminals are connected together in order to estab-
lish multi-voltage configurations, e.g. +5.1 V, ±12 V etc. the
common ground connecting point should be as close as
possible to the connector of the converter to avoid exces-
sive output ripple voltages.

Output Current Allocation for Special Types
Output currents differing from those given for standard
types (as per: Type Survey and Key Data) can be provided.
A maximum output power of 50 W should be considered, if
an ambient temperature range of –25...71°C is required.
The maximum permissible output currents are indicated in
the table below. If (upon customer's request) output volta-
ges are different from standard values, the relevant output
currents have to be adapted accordingly.
With reduced maximum ambient temperature or with forced
cooling, the total output power may exceed 50 W. Custom-
ized configurations always need to be checked by a feasibil-
ity study first. Please ask Power-One's sales engineers for
a proposal appropriate to your specific needs. See also:

Hold-up Time and Output Response
When the input voltage is switched off, the output voltage
will remain high for a certain hold-up time th (see fig.: Output
response as a function of input voltage or inhibit control) be-
fore the output voltage falls below 0.95 Uo nom. To achieve
the hold-up times indicated in fig.: Typical hold-up time th
versus relative input voltage at Io nom, AM, BM, CM, DM, FM
and CMZ, DMZ modules require an external series diode in
the input path. This is necessary to prevent the discharge of
the input capacitor through the source impedance or other
circuits connected to the same source. EM, LM and LMZ
modules have a built-in series diode. In AM, BM, CM, DM,
FM and CMZ, DMZ modules, no series diode is built-in,
since it would generate up to 10 W of additional power loss
inside the converter. Consequently the maximum opera-
tional ambient temperature would have to be reduced ac-
cordingly.
Note: For additional hold-up time see also Description of
Options: V ACFAIL Signal (VME).
The behavior of the outputs is similar with either the input
voltage applied or the inhibit switched low.
An output voltage overshoot will not occur when the module
is turned on or off.

Iinh [mA]
Note: With open i input: Output is disabled (Uo = off).
Uinh = 2.4 V
Uinh = 0.8 V
The outputs of the module may be enabled or disabled by
means of a logic signal (TTL, CMOS, etc.) applied between
the inhibit input i and the negative pin of output 1 (Vo1–). In
systems with several units, this feature can be used, for ex-
ample, to control the activation sequence of the converters.
If the inhibit function is not required, connect the inhibit pin
2 to pin 23 to enable the outputs (active low logic, fail safe).

Installation Instructions
The M series DC-DC converters are components, intended
exclusively for inclusion within other equipment by an in-
dustrial assembly operation or by professional installers. In-
stallation must strictly follow the national safety regulations
in compliance with the enclosure, mounting, creepage,
clearance, casualty, markings and segregation require-
ments of the end-use application. See also: Technical Infor-
mation: Installation and Application.
Make sure that there is sufficient air flow possible for con-
vection cooling. This should be verified by measuring the
case temperature when the unit is installed and operated in
the end-use application. The maximum specified case tem-
perature TC max shall not be exceeded. See also: Thermal
Considerations.
If the end-product is to be UL certified, the temperature of
the main isolation transformer should be evaluated as part
of the end-product investigation.
Connection to the system shall be made via the female con-
nector H11 (see Accessories). Other installation methods
may not meet the safety requirements.
Protection Degree
Condition: Female connector fitted to the unit.
IP 40: All units, except those with options P, A or K, and
except those with option D or V with potentiometer.
IP 30: All units fitted with options A or K, except those with
option P, and except those with option D or V with
potentiometer.
AM...LM DC-DC converters (class I equipment) are pro-
vided with pin no. 26 ( ), which is reliably connected with
their case. For safety reasons it is essential to connect this
pin with the protective earth of the supply system if required
in: Safety of operator accessible output circuit .
An input fuse is built-in in the connection from pin no. 32
(Vi– or P ) of the unit. Since this fuse is designed to protect
the unit in case of an overcurrent and does not necessarily
cover all customer needs, an external fuse suitable for the
application and in compliance with the local requirements
might be necessary in the wiring to one or both input pins
(no. 29 and/or no. 32).
IP 20: All units fitted with option P, or with option D or V with
potentiometer.
Cleaning Agents
In order to avoid possible damage, any penetration of liq-
uids (e.g. cleaning fluids) is to be prevented, since the
power supplies are not hermetically sealed.
Important: Whenever the inhibit function is not in use,
pin 2 (i) should be connected to pin 23 (Vo1–) to enable
the output(s).
Do not open the modules, or guarantee will be invali-
dated.

Safety of Operator Accessible Output Circuit
If the output circuit of a DC-DC converter is operator acces-
sible, it shall be an SELV circuit according to the IEC/EN
60950 related safety standards.
DC-DC converter to be an SELV circuit. Only voltage
adaption and rectification to the specified input voltage
range of the DC-DC converter is needed.
Since the M series DC-DC converters provide double or re-
inforced insulation between input and output, based on a
rated primary input voltage of 250 V AC and 400 V DC (for
class II units 250 V AC and DC), only operational insulation
is needed between the AC mains and the input of the DC-
DC converter. This means that there is no need for an elec-
trical isolation between the AC mains circuit and the DC-DC
converter input circuit to cause the output of an M series
The following table shows a possible installation configura-
tion, compliance with which causes the output circuit of the
DC-DC converter to be an SELV circuit according to IEC/
EN 60950 up to a configured output voltage (sum of nomi-
nal voltages if in series or +/– configuration) of 36 V.
However, it is the sole responsibility of the installer to as-
sure the compliance with the relevant and applicable safety
regulations. More information is given in: Technical Infor-
mation: Safety.

E Electronic Inrush Current Limitation
F Fuse Not Accessible
Available for CM, EM, LM and CMZ, LMZ types.
The standard M units have a fuseholder containing a 5 × 20
mm fuse which is externally accessible and to be found in
the back plate near the connector. Some applications re-
quire an inaccessible fuse. Option F provides a fuse moun-
ted directly onto the main PCB inside the case.
The standard version of the modules CM, DM, EM, LM as
well as CMZ, DMZ, LMZ include a passive inrush current
limitation in the form of a NTC resistor.
For applications which require an improved inrush current
limitation, an active electronic circuit as shown in fig. Option
E block diagram has been developed. Typical inrush cur-
rent waveforms of units equipped with this option are
shown below.
The full self-protecting functions of the module do normally
not lead to broken fuses, except as a result of inverse polar-
ity at the input of an AM, BM, CM, FM or CMZ type or if a
power component inside fails (switching transistor, free-
wheeling diode, etc). In such cases the defective unit has to
be returned to Power-One for repair.
CM and CMZ units meet the CEPT/ETSI standards for 48 V
DC supply voltage according to ETS 300132-2 if fitted with
option E combined with option D6 (input voltage monitor-
ing). Option D6, externally adjustable via potentiometer, is
necessary to disable the converter at input voltages below
the actual service ranges, avoiding an excessive input cur-
rent when the input voltage is raised slowly according to
ETS 300132-2. Option D6 threshold level Ut i + Uh i (refer to
description of option D) should be adjusted to 36.0...40.5 V
for 48 V DC nominal supply voltage (for 60 V DC systems,
threshold should be set to 44.0...50.0 V DC). The D output
(pin 5) should be connected to the inhibit (pin 2). For appli-
cations where potentiometers are not allowed refer to op-
tion D9.

If CM and CMZ types are driven by input voltages below
35 V DC or LM and LMZ types below 100 V AC, the maxi-
mum case temperature should be derated by 10 K or the to-
tal output power should be derated by 20%. EM, LM and
LMZ units driven by DC input voltages do not need to be
derated within the full specified input voltage range.

D Undervoltage Monitor
The input and/or output undervoltage monitoring circuit op-
erates independently of the built-in input undervoltage lock-
out circuit. A logic "low" (JFET output) or "high" signal (NPN
output) is generated at pin 5 as soon as one of the moni-
tored voltages drops below the preselected threshold level
Ut. The return for this signal is Vo1– (pin 23). The D output
recovers when the monitored voltage(s) exceed(s) Ut+Uh.
The threshold level Ut is either adjustable by a potentio-
meter, accessible through a hole in the front cover, or is fac-
tory adjusted to a fixed value specified by the customer.
Option D exists in various versions D0...D9 as shown in the
following table.

Threshold tolerances and hysteresis:
If Ui is monitored, the internal input voltage after the input
filter and rectifier (EM, LM and LMZ types) is measured.
Consequently this voltage differs from the voltage at the
connector pins by the voltage drop DUti across input filter
and rectifier. The threshold level of the D0 and D9 options is
factory adjusted at nominal output current Io nom and at TA =
25°C. The value of DUti depends upon the input voltage
range (AM, BM, ...), threshold level Ut, temperature and in-
put current. The input current is a function of the input volt-
age and the output power.

V ACFAIL Signal (VME)
Formula for additional external input capacitor
2 • Po • (th + 0.3 ms) • 100
Available for units with Uo1 = 5.1 V. This option defines an
undervoltage monitoring circuit for the input or the input and
main output voltage equivalent to option D and generates
the ACFAIL signal (V signal) which conforms to the VME
standard. The low state level of the ACFAIL signal is speci-
fied at a sink current of IV = 48 mA to UV ≤ 0.6 V (open-col-
lector output of a NPN transistor). The pull-up resistor feed-
ing the open-collector output should be placed on the VME
backplane.

where as:
Ci min = minimum internal input capacitance [mF], accord-
ing to the table below
Ci ext = external input capacitance [mF]
Po = output power [W]
η
th
= efficiency [%]
= hold-up time [ms]
After the ACFAIL signal has gone low, the VME standard
requires a hold-up time th of at least 4 ms before the 5.1 V
output drops to 4.875 V when the 5.1 V output is fully
loaded. This hold-up time th is provided by the internal input
capacitance. Consequently the working input voltage and
the threshold level Uti should be adequately above the mini-
mum input voltage Ui min of the converter so that enough
energy is remaining in the input capacitance. If the input
voltage is below the required level, an external hold-up ca-
pacitor (Ci ext) should be added.
Ui min = minimum input voltage [V]
Uti = threshold level [V]
Remarks: The threshold level Uti of option V2 and V3 is ad-
justed during manufacture to a value according to the table
below. A decoupling diode should be connected in series
with the input of AM, BM, CM, DM and FM converters to
avoid the input capacitance discharging through other
loads connected to the same source voltage. If LM or LMZ
units are AC powered, an external input capacitor cannot
be applied unless an additional rectifier is provided.

If Ui is monitored, the internal input voltage is measured af-

Consequently this voltage differs from the voltage at the
connector pins by the voltage drop ∆Ut i across input filter
and rectifier. The threshold level of option V0 is factory ad-
justed at Io nom and TA = 25°C. The value of ∆Ut i depends
upon the input voltage range (AM, BM, ...), threshold level
Ut i, temperature and input current. The input current is a
function of input voltage and output power.
