Full input-to-output, input-to-case, output-to-case, and output
to output isolation is provided. The converters are designed,
built, and safety-approved to the international safety standards
IEC/EN 60950-1. They are particulary suitable for railway
applications and comply with EN 50155 and EN 50121-2-3.
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 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.
The converter inputs are protected against surges and
transients. 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.
A temperature sensor generates an inhibit signal, which
disables the outputs when 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.
All outputs are open- and short-circuit proof, and are protected
against overvoltages by means of built-in suppressor diodes.
The output can be inhibited by a logic signal applied to pin 18
(i). The inhibit function is not used, pin 18 must be connected
with pin 14 to enable the outputs.
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.
LED indicators display the status of the converter and allow for
visual monitoring of the system at any time.
Important: For applications requiring compliance with IEC/EN
61000-3-2 (harmonic distortion), please use our LK4000 or
LK5000 Series with incorporated power factor correction (PFC).
