Summary
of several units, current sharing option is provided by a sin-
gle wire interconnection.
These extremely compact DC-DC converters incorporate
all necessary input and output filtering, signalling and pro-
tection features which according to the latest industry
standards are required in the majority of applications. The
converters provide important advantages such as flexible
output power through primary current limitation, extremely
high efficiency, excellent reliability, very low ripple and RFI
noise levels, full input to output isolation, negligible inrush
current, soft start, overtemperature protection and input
over-/undervoltage lock-out. The converter inputs are pro-
tected against surges and transients occurring on the
source lines, covering a total input voltage range from
16 V DC up to 150 V DC with five different types.
As a modular power supply or as part of a distributed power
supply system, the low profile design significantly reduces
the necessary power supply volume without sacrificing high
reliability.
The units are designed as forward converters using planar
magnetics and control circuits in hybrid technology. The
switching frequency is fix at 307 kHz under normal operat-
ing conditions. Triple and quadruple output modules have
their voltage regulation of output 3 and 4 relying on the
close magnetic coupling of transformer and output conduc-
tor together with the circuit symmetry of their main outputs
2, respectively 1. Outputs with an equal output voltage can
either be series or parallel connected.
The outputs are continuously open- and short-circuit proof.
LEDs at the front panel and an isolated output power good
option indicate the status of the power supply modules.
Voltage suppressor diodes protect the outputs against an
internally generated overvoltage.
The fully enclosed, black coated aluminium case acts as
heat sink and RFI shield. It is particularly suitable for 19"
rack systems occupying 3U/4TE only, but can also be
chassis-mounted by means of four M3 screws. Connector
type is H15 and for single output modules H15 S2.
Full system flexibility and n+1 redundant operating mode
are possible due to virtually unrestricted series or parallel
connection capabilities of all outputs. In parallel connection

Connector Pin Allocation
The connector pin allocation table defines the electrical potentials and the physical pin positions on the H15 connector. Pin
no. 26, the protective earth pin present on all BP…GP DC-DC converters is leading, ensuring that it makes contact with the
female connector first.

Installation Instruction
The P series DC-DC converters are components, intended
exclusively for inclusion within other equipment by an in-
dustrial assembly operation or by professional installers.
Installation must strictly follow the national safety regula-
tions in compliance with the enclosure, mounting, creep-
age, clearance, casualty, markings and segregation re-
quirements of the end-use application. See also: Technical
Information: Installation and Application.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids is to be prevented, since the power supplies
are not hermetically sealed.
Standards and approvals
All P series DC-DC converters correspond to class I equip-
ment.
Connection to the system shall be made via the female
connector H15 or H15 S2 (see: Accessories) according to
Connector pin allocation. Other installation methods may
not meet the safety requirements.
They are pending to be UL recognized according to UL
1950, UL recognized for Canada to CAN/CSA C22.2 No.
950-95 and LGA approved to IEC/EN 60950 standards and
have been designed in accordance with these standards
for:
Check for hazardous voltages before altering any connec-
tions.
• Building in
• Basic insulation between input and case, based on
250 V AC or 240 V DC
• Double or reinforced insulation between input and out-
put, based on 250 V AC or 240 V DC
The DC-DC converters are provided with pin no. 26 ( ),
which is reliably connected to the case. For safety reasons
it is essential to connect these pins to the protective earth of
the supply system if required in: Safety of operator accessi-
ble output circuit.
• Operational insulation between output(s) and case
• Operational insulation between the outputs
• Operational insulation between option D or i and out-
put(s)
• Operational insulation between option D or i and case
• The use in a pollution degree 2 environment
• Connecting the input to a primary circuit with a maximum
transient rating of 2500 V (overvoltage class III based on
a 110 V primary circuit, overvoltage class II based on a
230 V primary circuit).
The Vi 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 local requirements.
Important: Whenever the inhibit function is not in use,
pin 28 (i) should be connected to pin 32 (Vi–) to enable
the output(s).
After approvals, the AC-DC converters are subject to
manufacturing surveillance in accordance with the above
mentioned UL, CSA, EN and with ISO 9001 standards.
Do not open the modules, or guarantee will be invalidated.
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 must not be overridden.
Protection Degree
Condition: Female connector fitted to the unit.
The protection degree of the DC-DC converters is IP 40.
Ensure that a unit failure (e.g. by an internal short-circuit)
does not result in a hazardous condition. See also: Safety
of operator accessible output circuit.
Isolation
The electric strength test is performed as factory test in accordance with IEC/EN 60950 and UL 1950 and should not be
repeated in the field. Melcher will not honour any guarantee claims resulting from electric strength field tests.

Safety of operator accessible output circuit

cessible, it shall be an SELV circuit according to IEC/EN
60950 related safety standards

However, it is the sole responsibility of the installer to as-
sure the compliance with the relevant and applicable safety
regulations. More information about this subject and about
output circuits at hazardous voltages are given in: Techni-
cal Information: Safety.
The following table shows some possible installation con-
figurations, 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
