High input voltage (1200Vdc), wide input range DC-DC converter for 5kW, 24Vdc applications

ABSOPULSE Electronics Ltd
High input voltage (1200Vdc), wide input range (1000-1400Vdc) DC-DC converter for power systems that transmit high voltage and high power over long distances

The HVT 5K-1200/24-4U7 is a high input voltage, industrial quality DC-DC converter designed for driving low voltage 24Vdc equipment in 5kW applications. The converter is typically designed into power systems that transmit high voltage and high power over long distances.  Several units can be parallel connected for 10kW, 20kW and higher output power.

The unit converts a high input voltage direct current of 1200Vdc (1000Vdc to 1400Vdc range), to 24Vdc/208A. The output can be customized for other output voltages. Input to output safety isolation is 5500Vdc and input to chassis isolation is 5000Vdc. Conversion efficiency is typically 85% at 1200Vdc nominal input, at full load.

The HVT 5K-1200/24-4U7 is cooled by high quality built-in fans that ensure operation over a 0°C to +50°C temperature range for full specification. Wider temperature ranges are available on request. The 176.5 x 432 x 419 mm chassis is ruggedly constructed and is designed to withstand high levels of shock and vibration to IEC 61373 Cat 1 A&B. Conformal coating provides protection against humidity and airborne contaminants.

The input and output on this converter are filtered for low noise. The input meets the requirements for EN55032 Class A with wide margins. Class B is available on request. This ensures that the unit can be used in EMI sensitive environments without additional filtering. Electronic protection includes inrush current limiting, reverse polarity protection, output current limiting and short-circuit protection. The unit is designed for compliance with EN62368-1 and equivalent safety standards. Low component count, large design headroom, and the exclusive use of components with established reliability also contribute to ensuring that the unit delivers many years of problem free operation.
