Description
The DC-DC converters have been developed as a re-
sponse to the increasing need for decentralised power sup-
ply systems. They are especially suitable for powering me-
dium loads on PCBs and for realising redundant systems.
The DC-DC converters feature high efficiency, low output
ripple, low module height, high quality and reliability. To
minimise feedback effects in the supply system, the mod-
ules are equipped with an efficient low-pass Pi input filter.
All modules are manufactured according to ISO 9001.
Case: 2"× 2" metal, black anodized, self cooling (free air
convection).

Safety Instructions
If the output circuit of a DC-DC converter is operator-acces-
sible according to the IEC 950 related safety standards, it
shall be an SELV circuit (Safety Extra Low Voltage circuit,
i.e. a circuit, separated from mains by at least basic insula-
tion, that is so designed and protected that under normal
and single fault conditions, the voltage between any two
conductors and between any conductor and earth does not
exceed 60 V DC).
In the following section an interpretation is provided of the
IEC 950 safety standard with respect to the safety status of
the output circuit. However, it is the sole responsibility of the
installer or user to assure the compliance with the relevant
and applicable safety standards.
If the following table is observed, the output of any DC-DC
converter is considered to be an SELV circuit up to a nomi-
nal output voltage of 30 V (2 x 15 V in series).

3 Has to be insulated from earth by double or reinforced insulation according to the relevant safety standard, based on the maximum in-
put voltage of the DC-DC converter.

Isolation Tests
Table 8: Isolation test voltage, coupling capacitance and
insulation resistance
Input to output isolation voltage tests are performed as fac-
tory tests (100%) and should not be repeated in the field.
Melcher will not honour any guarantee/warranty claims re-
sulting from high voltage field tests.

Connection in Series
If the outputs of one or more units are connected in series
each individual output should be protected by a zener diode
or preferably by a suppressor diode to avoid overvoltages
or reverse polarity at the individual outputs, e.g.:
– 1N5908 to protect 5 V outputs
+Vo
+Uo
Unit 1
Go
– BZW04-11 to protect 12 V outputs
– BZW04-14 to protect 15 V outputs
–Vo
(or equivalent types)
Such destructive voltages may occur at switch-on cycle of
the converters, if the output voltages do not rise at the same
time. The "slower" output(s) could be supplied and, as a
result, destroyed by the "faster" output(s) via the load. The
maximum output current is limited by the lowest current
limitation.
+Vo

Connection in Parallel
–Vo
–Uo
Connection of the outputs of one or more units in parallel is
not permitted. The load distribution and the ripple values
could not be controlled.

Outputs connected in series
Exception: .. ICR 5-05 (all 5 V single output units)
Cleaning
Submersion of the units in water for rinsing is permitted.
Drying should be done in the air.
Two CFC free cleaning solvents have been tested and can
be recommended:
– Prozone from BP
– Zestron from Dr. O. K. Wack Chemie GmbH (Germany)
