Summary
The KP series is an extension of the K series of AC-DC con-
verters with an increased output power level of up to 280 W
depending on the operating ambient temperature require-
ments. The KP converters are optimized for use in
230 V AC mains applications and feature high efficiency,
high reliability, low output voltage noise and excellent dy-
namic 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 curcuitry disables the outputs if the
input voltage is outside the specified range. The LKP types
include an inrush current limitation preventing circuit break-
ers and fuses from being damaged at switch-on.
The 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
applied to the connector pin 18 (i). If the inhibit function is
not used pin 18 must be connected with pin 14 to enable
the outputs (fail safe).
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.
The case design allows operation up to an operating ambi-
ent temperature of 71
°C with reduced output power. De-
pending on the ambient temperature requirements, how-
ever, the output power can be up to 280 W.
An internal temperature sensor generates an inhibit signal
which disables the outputs if the case temperature
TC ex-
ceeds the specified 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. Especially for battery charger applica-
tions an external temperature sensor has been designed to
allow for temperature compensated battery charging.
The modules may either be plugged into 19" rack systems
according to DIN 41494 or be chassis mounted.
