Summary
The K 4000/5000-series of AC-DC converters represents a
flexible range of power supplies for use in advanced elec-
tronic systems. Features include full power factor correc-
tion, high efficiency, high reliability, low output voltage noise
and excellent dynamic response to load/line changes.
IEC/EN 60950 and have been approved by the safety
agencies LGA (Germany) and 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.
The converter inputs are protected against surges and tran-
sients occurring at the source lines. An input over- and
undervoltage lock-out circuitry disables the outputs if the
input voltage is outside the specified ranges. Inrush current
limitation is included preventing circuit breakers and fuses
from being damaged at switch-on.
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.
All outputs are overload, open- and short-circuit proof and
are protected against overvoltages by means of a built-in
suppressor diode. The outputs can be inhibited by a logic
signal applied to the connector pin 18 (i). If the inhibit func-
tion is not used pin 18 must be connected with pin 14 to en-
able the outputs.
Various options are available to adapt the converters to in-
dividual applications.
The modules may either be plugged into 19 inch rack sys-
tems according to DIN 41494, or be chassis mounted.
LED indicators display the status of the converter and allow
visual monitoring of the system at any time.
Important: These products are intended to replace the
LK 1000 and LK 2000 in order to comply with IEC/EN
61000-3-2.
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
