K Series with PFC Data Sheet
150 – 280 Watt AC-DC Converters
the temperature drops below the limit.
Various options are available to adapt the converters to
individual applications. An external temperature sensor is
available to allow for temperature adapted battery
charging.
The converters may either be plugged into 19" rack
systems according to IEC 60297-3, or be mounted on a
chassis or plate.
Important :
These products are intended to replace the LK1000 and
LK2000 models, in order to comply with IEC/EN 61000-3-2.
For applications with DC input or main frequencies other than
50/60 Hz, the LK1000 and LK2000 models are still available.
Model Selection
Non-standard input/output configurations or special customer adaptations are available on request.
