The M series of AC-DC (DC-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 Input. An input over- and under-
voltage lock-out circuitry disables the outputs if the input
voltage is outside the specified range. These types include
an inrush current limitation preventing circuit breakers and
fuses from being damaged at switch-on.
cies LGA (Germany) and UL (USA). The UL Mark for
Canada has been officially recognized by 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 agen-
The modules may either be plugged into 19" rack systems
according to DIN 41494, or be chassis mounted.

Functional Description
The auxiliary outputs Uo2 and Uo3 are individually regulated
by means of secondary switching transistors. Each auxili-
ary 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.
The input voltage is fed via an input fuse, an input filter, a
rectifier and an inrush current limiter to the input capacitor.
This capacitor sources a single transistor forward converter.
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 primary switching
transistor. This signal is fed back via a coupling transformer.

Input fuse
Input Under-/Overvoltage Lock-out
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.
For applications where the fuse should be inaccessible: see
Option F.
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).
Inrush Current
Table 4: Fuse type (slow-blow)
The modules incorporate an NTC resistor in the input cir-
cuitry which (during the initial switch-on cycle) limits the
peak inrush current to avoid damage to connectors and
switching devices. Subsequent switch-on cycles within a
short interval will cause an increase of the peak inrush cur-
rent due to the warming up of the NTC resistor. Refer also
to: Option E description.

Thermal Considerations
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.
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-
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.
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.
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.
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.
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.
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.
Io/Io nom
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.

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

bility study first. Please ask Power-One's sales engineers
for a proposal appropriate to your specific needs. See also:
Commercial Information: Inquiry Form for Customized
Power Supply.
Thermal Protection
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.

When the input voltage is switched off, the output voltage
will remain high for a certain hold-up time th before the out-
put voltage falls below 0.95 Uo nom
.

Auxiliary Functions
i Inhibit for Remote On and Off
Note: With open i input: Output is disabled (Uo = off).
For output response refer to Hold-up Time and Output Re-
sponse.
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).

Safety and Installation Instructions
Connector pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H11 con-
nector. Pin no. 26, the protective earth pin present on all LM

Installation Instructions
The M series AC-DC converters are components, intended
Important: Whenever the inhibit function is not in use,
pin no. 2 (i) should be connected to pin no. 23 (Vo1-) to
enable the output(s).
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.
Do not open the modules, or guarantee will be invali-
dated.
Make sure that there is sufficient air flow available 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.
Connection to the system shall be made via the female con-
nector H11 (see: Accessories). Other installation methods
may not meet the safety requirements.
LMAC-DC converters (class I equipment) are provided 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.
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.
Cleaning Agents
The P input (pin no. 32) is internally fused. This fuse is de-
signed to protect the unit in case of overcurrent and may not
be able to satisfy all customer requirements. External fuses
in the wiring to one or both input pins (no. 30 and/or no. 32)
may therefore be necessary to ensure compliance with lo-
cal requirements. See also: Input Fuse.
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.

Safety of operator accessible output circuit
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 Informa-
tion: Safety.
If the output circuit of an AC-DC converter is operator ac-
cessible, it shall be an SELV circuit according to the IEC/EN
60950 related safety standards.
The following table shows a possible installation configura-
tion, compliance with which causes the output circuit of an
M series AC-DC converter to be an SELV circuit according
to IEC/EN 60950 up to a configured output voltage (sum of
nominal voltages if in series or +/– configuration) of 36 V.
If the M series AC-DC converters are used as DC-DC con-
verters, please refer to the data sheet: DC-DC converters
≤100 Watt M series.

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 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 out-
put current Io nom and at TA = 25°C. The value of DUti de-
pends upon the threshold level Ut, temperature and input
current. The input current is a function of the input voltage
and the output power.

V ACFAIL signal (VME)
If the input voltage is below the required level, an external
hold-up capacitor (Ci ext) should be added. If the units are
AC powered, an external input capacitor cannot be applied
unless an additional rectifier is provided.
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 specified at a
sink current of IV = 48 mA to UV ≤ 0.6 V (open-collector out-
put of a NPN transistor). The pull-up resistor feeding the
open-collector output should be placed on the VME back-
plane.
whereas:
Ci min = minimum internal input capacitance [mF], accord-
ing to the table below
Ci ext = external input capacitance [mF]
Po = output power [W]
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 Ut should be adequately above the mini-
mum input voltage Ui min of the converter so that enough
energy is remaining in the input capacitance.

Option V operates independently of the built-in input under-
voltage lock-out circuit. A logic "low" signal is generated at
pin 5 as soon as one of the monitored voltages drops below
the preselected threshold level Ut. The return for this signal
is Vo1– (pin 23). The V output recovers when the monitored
voltage(s) exceed(s) Ut + Uh. The threshold level Ut is either
adjustable by a potentiometer, accessible through a hole in
the front cover, or is factory adjusted to a determined cus-
tomer specified value.

V output (V0, V2, V3):
Vo1+
Connector pin V is internally connected to the open collec-
tor of a NPN transistor. The emitter is connected to the
negative potential of output 1. UV ≤ 0.6 V (logic low) corre-
sponds to a monitored voltage level (Ui and/or Uo1) < Ut.
The current IV through the open collector should not exceed
50 mA. The NPN output is not protected against external
overvoltages. UV should not exceed 80 V.

Threshold tolerances and hysteresis:
If Ui is monitored, the internal input voltage is measured af-
ter the input filter and rectifier. 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 option V0 is factory adjusted at Io nom and TA = 25°C. The
value of DUti depends upon the threshold level Uti , tem-
perature and input current. The input current is a function of
input voltage and output power.
