Power Supply / Management Engineering dc-dc converters

ABSOPULSE BHT-319R-F4 series of dc-dc converters have an operational life of 30 years at high temperatures in railway and industrial environments. The convection cooled units deliver 300W continuous output power over a -40°C to +85°C temperature range without derating. By eliminating optocouplers and electrolytic capacitors, the MTBF of the units is significantly higher than in conventional converter designs. http://www.absopulse.com
