Description
The K Series of DC-DC and AC-DC converters represents a
broad and flexible range of power supplies for use in advanced
electronic systems. Features include high efficiency, high
reliability, low output voltage noise and excellent dynamic
response to load/line changes. LK models can be powered by
DC or AC with a wide-input frequency range (without PFC).
The converter inputs are protected against surges and
transients. An input over- and undervoltage lockout circuitry
disables the outputs if the input voltage is outside of the
specified range. Certain types include an inrush current limiter
preventing circuit breakers and fuses from tripping at switch-on.
All outputs are open- and short-circuit proof and are protected
against overvoltages by means of built-in suppressor diodes.
The outputs can be inhibited by a logic signal applied to pin 18
(i). 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 for
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 and EN50155. They have been approved by the safety
agencies TÜV 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.
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.
Various options are available to adapt the converters to individual
applications.
The converters may either be plugged into a 19" rack system
according to IEC 60297-3, or be chassis mounted. They are ideally
suited for Railway applications.
Important: For applications requiring compliance with IEC/EN 61000-3-2
(harmonic distortion), please use our LK4000 and LK5000 Series with
incorporated power factor correction (PFC).
