Powerstax – New 500W high-voltage full-brick performs in tough environments (F501-385 DC-DC converter)

Powerstax has launched its latest power converter, the F501-385, a 500W output full-brick high-voltage DC-DC converter for rugged environments. It joins a wide range of field-proven power converters which offer users a low NRE, rapid time to market power system development route.

The new F501-385 DC-DC converter operates over the input range 355-400VDC and provides 24, 28, 48, 56VDC output and 500W power. By combining a number of F501-385 bricks in series significantly higher output voltages can be produced and if up to twenty F501-385 bricks are paralleled a 10kW system can be produced.

With a power density of 5.53W/cm3, typical efficiency of 90%, active load sharing, remote on/off, base plate cooling and low start-up temperature of -40C, the unit offers users reduced energy costs, greater return on investment, greater reliability and longer product life.

The Powerstax F501-385 provides system designers with a comprehensive list of in-built protection functions such as over-voltage protection, under-voltage protection and short-circuit protection are complemented by features such as a thermal monitoring signal to provide early warning of potential system faults.

The F501-385 is designed to operate as an integral part of a complete distributed power system, with or without hold-up. Typical applications for the F501-385 include military and commercial based wireless systems, radar and communication systems, telecom infrastructure and security systems, says the company.
