Features include full power factor correction, good hold-up time, high Full input to output, input to case, output to case and output to efficiency and reliability, low output noise, and excellent output isolation is provided. The converters are designed and dynamic response to load/line changes. built according to the international safety standards IEC/EN nd 60950-1 2 Ed. They have been approved by safety The converters are protected against surges and transients agencies. occurring at the source lines.

These products are intended to replace the LK1000 and LK2000 Various options are available to adapt the converters to models, in order to comply with IEC/EN 61000-3-2. For appli- cations with DC input or main frequencies other than 50/60 Hz, the individual applications. An external temperature sensor is LK1000 and LK2000 model types are still available. available to allow for temperature adapted battery charging.
