K Series with PFC 150 - 280 Watt AC-DC Converters The LK4000/5000 Series of AC-DC converters represents a flexible range of power supplies for use in advanced electronic systems the LKP models are an extension with increased output power, but optimized to 230 VAC. Features include full power factor correction, good hold-up time, high efficiency and reliability, low output noise, and excellent dynamic response to load/line changes. The converters are protected against surges and transients occurring at the source lines. Input over- and undervoltage lockout circuitry disables the outputs, when the input voltage is outside of the specified range. Input inrush current limitation is included for preventing circuit breakers and fuses from tripping at switch-on.

The outputs can be inhibited by a logic signal applied to connector pin 18. If the inhibit function is not used, pin 18 must be connected with pin 14 to enable 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 converters are designed and built according to the international safety standards IEC/EN 62368-1. They have been approved by safety agencies. 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. However, higher output power up to 280 W is possible depending on environmental conditions and converter model. An internal temperature sensor generates an inhibit signal, which disables the outputs, when the case temperature T exceeds C the limit. The outputs automatically recover, when 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 appli -cations with DC input or main frequencies other than 50/60 Hz, the LK1000 and LK2000 model types are still available. Model Selection Non-standard input/output configurations or special customer adaptations are available on request.
