DC/DC converters designed for heavy duty industrial applications
ABSOPULSE Electronics has released the HHT 500-FX series of DC/DC converters designed for heavy duty industrial applications that require high DC-input voltage at high operating temperatures.
The converters operate over a wide baseplate temperature range of -40 to 85°C for full specification without the need for derating. They accept high DC-input voltages and offer wide input ranges including 400VDC (300-500V range), 500VDC (400-600V range) or 600VDC (500-700V range).
The units deliver 500W continuous output power and provide 24, 48, 72V or 125VDC output voltage. Custom input and output voltages are available. The input and output are filtered for low noise. The input meets EN55022 Class A with wide margins, with Class B available as an option. Efficiency is a minimum of 85% at full load depending on the input/output configuration required.
Low component count, large design headroom, 4300VDC I/O isolation and full electronic protection contribute to a minimum MTBF of 160,000 hours at 60°C. The internal boards are conformal coated for immunity to humidity and contamination, and the robust construction ensures protection from high levels of shock and vibration, also contributing to the long operating life of the unit.
The converters comply with EN/UL60950-1 and equivalent industrial safety standards.
