Summary
The K series of AC-DC (DC-DC) converters represents a
flexible range of power supplies for use in advanced elec-
tronic systems. Features include wide input frequency
range (no PFC), high efficiency, high reliability, low output
voltage noise and excellent dynamic response to load/line
changes.
The converter inputs are protected against surges and tran-
sients occuring at the source lines. An input over- and
undervoltage lock-out circuitry disables the outputs if the
input voltage is outside the specified range. Certain types
include an inrush current limitation preventing circuit break-
ers and fuses from being damaged at switch-on.
All outputs are open- and short-circuit proof and are pro-
tected against overvoltages by means of a built-in suppres-
sor diode. The outputs can be inhibited by a logic signal ap-
plied to the connector pin 18 (i). If the inhibit function is not
used pin 18 must be connected to pin 14 to enable the out-
puts.
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 modules are designed
and built according to the international safety standards
IEC/EN 60950 and have been approved by the safety
agencies LGA (Germany) und UL (USA). The UL Mark for
Canada has been officially recognized by regulatory au-
thorities in provinces across 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
T
C
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 in-
dividual applications.
The modules may either be plugged into 19" rack systems
according to DIN 41494, or be chassis mounted.
Important:
For applications with requirements for com-
pliance with IEC/EN 61000-3-2 (harmonic distortion)
please use our LK 4000 and LK 5000 series.
