Summary
The LPC series is a range of non isolated AC-DC convert-
ers for use as power factor corrected front ends capable of
delivering up to 230 Watt at nominal output voltages of up to
85V. For higher power requirements, several units may be
connected in parallel.
The AC-DC converters are ideally adapted to mains opera-
tion due to their universal input voltage range. Key features
are: Power factor correction, low input harmonic distortion,
no inrush current, low RFI, high immunity to electrical dis-
turbances and high efficiency over the entire input voltage
range.
The outputs are no load, overload and short-circuit proof
and are protected against overvoltages by means of a built-
in suppressor diode.
The converters are especially suited to powering Melcher
DC-DC converters of the P and Q series which, depending
on the mains input voltage level, provide the necessary
electrical isolation for SELV (Safety Extra Low Voltage) out-
puts.
The OK LED displays the status of the converter and allows
visual monitoring of the system at any time.
The AC-DC converters are designed and built according to
the international safety standards IEC/EN 60950, UL 1950,
CAN/CSA C22.2 No.950-95, LGA , UL and cUL. Approvals
are in progress.
The converters are based on a single PCB with high power
density. The thermal concept allows operation at full load
up to an ambient temperature of 71
°C in free air without
forced cooling. If forced air cooling is provided the ambient
temperature may exceed 71
°C but the case temperature
TC must remain below 95
°C under all operating conditions.
Semiconductors and other heat generating components
are mounted in such a way that the generated heat is
transfered directly to the rugged metallic case. High effi-
ciency, low heat dissipation and careful consideration of
possible thermal stresses ensure no hot spots and high re-
liability. A built-in temperature sensor generates an inhibit
signal which disables the output if the case temperature
TC exceeds 95
°C. The output is automatically re-enabled
when the temperature returns below this limit.
A special feature of the LPC front end is the extremely slim
case, just 4TE wide.
The modules are plug-in types fitted with an H15 connector
for use in 19" rack systems according to DIN 41494.
