Description
The H-family of AC-DC converters represents a broad and
flexible range of power supplies for use in advanced elec-
tronic systems. Features include high efficiency, reliability
and low output voltage noise.
IEC 950 and have been approved by the safety agencies
LGA (Germany) and UL (USA). The UL Mark for Canada
has been officially recognized be regulatory authorities in
provinces across Canada.
The converter inputs are protected against surges and tran-
sients occuring at the source lines. An input over- and
undervoltage cut-out circuitry disables the outputs if the in-
put voltage is outside the specified range. The modules in-
clude an inrush current limitation preventing circuit break-
ers and fuses from being damaged at switch-on.
The case design allows operation at nominal load up to
50°C in a free air ambient temperature. If forced cooling is
provided, the ambient temperature may exceed 50°C but
the case temperature should remain below 80°C under all
conditions.
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.
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 with pin 23 to enable the
outputs.
Various options are available to adapt the converters to in-
dividual applications.
The modules may either be plugged into 19 inch rack sys-
tems according to DIN 41494, or be chassis mounted.
LED indicators display the status of the converter and allow
visual monitoring of the system at any time.
Case: aluminium, black finish, self cooling.
Dimensions: 38.7 × 111.2 × 168.5 mm. Weight: 770 g
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

Safety and Installation Instructions
Safety
If the output circuit of an AC-DC converter is operator-ac-
cessible 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 such that under nor-
mal and single fault conditions, the voltage between any
two conductors and between any conductor and earth does
not exceed 60 V DC).
For safety reasons, the modules must be wired via the
female connector H11 (according to DIN 41612 see sec-
tion "Accessories") in order to meet national and interna-
tional safety requirements!
The connector protective earthing pin is leading. During the
production process, all transformers and each of the fully
assembled modules are individually tested for electric
strength and earth continuity (see "Supplementary Data").
All electric strength tests are performed as factory tests.
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:
Installation Instruction
Installation of the power supply must strictly follow the na-
tional safety regulations. To observe the safety require-
ments according to EN 60950/IEC 950, the module shall be
connected via the female connector type H11 see section
"Accessories".Other installation methods may not meet the
safety requirements. The modules do not incorporate any
fuse. At least one external fuse, installed in the wiring to the
input is essential! See "Fuse types".
If the AC-DC converter is installed according to the relevant
safety regulations its outputs are considered to be SELV
circuits up to a nominal output voltage of 36 V.
Whenever the inhibit function is not required, pin 2 (i)
should be connected to pin 23 to enable the output(s).
Important Advice
Electric strength tests should not be repeated in the field. Improper test methods, for example overshooting or oscillating
test voltages, voltage slopes exceeding 1 kV/µs, internal Y-capacitors not carefully discharged, etc. can cause severe
damage to switching devices and ICs. Melcher AG will not honour any guarantee/warranty claims resulting from high
voltage field tests.

Functional Description
The input voltage is fed via an input filter, an inrush current
limiter and a bridge rectifier to the input capacitor. This ca-
pacitor 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. The control logic
senses the main output voltage Uo1 and generates, with re-
spect to the maximum admissible output currents, the con-
trol signal for the primary switching transistor. This signal is
fed back via a coupling transformer.
The auxiliary outputs Uo2 and Uo3 are unregulated. Each
auxiliary output's current is sensed and transferred to the
main control circuit using a current transformer. If one of the
outputs is driven into current limit, the other outputs will re-
duce their output voltages as well because all output cur-
rents are controlled by the same control circuit.

Input fuse
The modules do not incorporate any fuse. External fuses in-
stalled in the wiring to the input are essential.
If the input voltage remains below 0.6 Ui min or exceeds
1.1 Ui 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 above).

Output Protection
Uo
Uo nom
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.

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. Outputs one and two of a dual output unit may be
connected parallel without a minimum current requirement
at the main output. Outputs two and three of a triple output
unit can be connected in parallel.
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.
In parallel operation, one or more of the outputs may oper-
ate continuously in current limit which will cause an in-
crease in case temperature. Consequently, a reduction of
the max. ambient temperature by 10 K is recommended.
Inhibit (i Input)
The outputs of the module may be enabled or disabled by
means of a logic signal (TTL, CMOS, etc.) applied to the
inhibit input. If the inhibit function is not required, connect
the inhibit pin 2 to pin 23 to enable the outputs (active low
logic, fail safe).

Important Advice
Testing by applying AC voltages will result in high and
dangerous leakage currents through the Y-capacitors
(see fig. 1). Melcher will not honour any guarantee/war-
ranty claims resulting from high voltage field tests. Ref-
erence is also made to chapter: "Safety and Installation
Instructions".
Input to output electric strength tests, in accordance with
the safety standards IEC 950, EN 60950, VDE 0805 and
EN 41003 are performed as factory tests and should not be
repeated in the field.

Option 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 D1...D8 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 ∆Uti across the input filter. The value of ∆Uti depends
upon the input voltage range, threshold level Ut, tempera-
ture and input current. The input current is a function of the
input voltage and the output power.

Option V ACFAIL signal (VME)
Formula for threshold level for desired value of th:
This option defines an undervoltage monitoring circuit
for the input or the input and main output voltage
(Uo1 nom = 5.1 V only) 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.

Ui min = minimum input voltage [V]
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.
Uti = threshold level [V]
Remarks:
The threshold level Uti of option V2 and V3 is adjusted dur-
ing manufacture to a value according to table "Undervol-
tage monitor functions", section "Option D").
A decoupling diode should be connected in series with the
input to avoid the input capacitance discharging through
other loads connected to the same source voltage.

Option V operates independently of the built-in input under-
