Description
The LK 4000/5000 Series of AC-DC converters represents
a flexible range of power supplies for use in advanced
electronic systems; the LKP models are an extension with
increased output power, but optimized to 230 VAC.
Features include full power factor correction, good hold-up
time, high efficiency and reliability, low output noise, and
excellent dynamic response to load/line changes.
The
converters
are
protected
against
surges
and
transients occurring at the source lines. Input over- and
undervoltage lockout circuitry disables the outputs, when
the input voltage is outside of the specified range. Input
inrush current limitation is included for preventing circuit
breakers and fuses from tripping at switch-on.
All outputs are overload, open- and short-circuit proof, and
protected by a built-in suppressor diode. The outputs can
be inhibited by a logic signal applied to connector pin 18. If
the inhibit function is not used, pin 18 must be connected
with pin 14 to enable the outputs.
LED indicators display the status of the converter and
allow visual monitoring of the system at any time.
Full input to output, input to case, output to case and
output to output isolation is provided. The converters are
designed and built according to the international safety
standards IEC/EN 60950-1. They have been approved by
the safety agencies TV and UL (for USA and Canada).
The case design allows operation at nominal load up to
71 °C in a free air ambient temperature. If forced cooling is
provided, the ambient temperature may exceed 71 °C, but
the case temperature must remain below 95 °C under all
conditions. However, higher output power up to 280 W is
possible depending on environmental conditions and
converter model.
An internal temperature sensor generates an inhibit signal,
which disables the outputs, when the case temperature TC
exceeds the limit. The outputs automatically recover, when
the temperature drops below the limit.
