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 T_Cexceeds 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 U_o1and 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 U_o2and U_o3are 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 U_{i min}or exceeds

1.1 U_{i max}(approx. values), an internally generated inhibit

signal disables the output(s). When checking this function

the absolute maximum input voltage rating U_{i abs}must be

carefully considered (see table above).

Output Protection

U_o

U_{o 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

U_t. The return for this signal is Vo1– (pin 23). The D output

recovers when the monitored voltage(s) exceed(s) U_t+U_h.

The threshold level U_tis 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.

differs from the voltage at the connector pins by the voltage

upon the input voltage range, threshold level U_t, tempera-

Option V ACFAIL signal (VME)

Formula for threshold level for desired value of t_h:

This option defines an undervoltage monitoring circuit

for the input or the input and main output voltage

(U_{o1 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 I_V= 48 mA to U_V≤ 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.

U_{i min}= minimum input voltage [V]

After the ACFAIL signal has gone low, the VME standard

requires a hold-up time t_hof 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 t_his provided by the internal input

capacitance. Consequently the working input voltage and

the threshold level U_tishould be adequately above the mini-

mum input voltage U_{i min}of the converter so that enough

energy is remaining in the input capacitance.

U_ti= threshold level [V]

Remarks:

The threshold level U_tiof 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.
