Summary
The K 4000/5000-series of AC-DC converters represents a
exible range of power supplies for use in advanced elec-
tronic systems. Features include full power factor correc-
tion, high efciency, high reliability, low output voltage noise
and excellent dynamic response to load/line changes.
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 specied ranges. Inrush current
limitation is included preventing circuit breakers and fuses
from being damaged at switch-on.
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.
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) and UL (USA). The UL Mark for
Canada has been ofcially 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
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 in-
dividual applications.
The modules may either be plugged into 19 inch rack sys-
tems according to DIN 41494, or be chassis mounted.
Important: These products are intended to replace the
LK 1000 and LK 2000 in order to comply with IEC/EN
61000-3-2.
