Absopulse’s DRH-150 wide input range, long-life DC/DC converter for rugged industrial environments is designed for an operating life of up to 30 years. By eliminating optocouplers in the feedback loop and significantly reducing component count, the MTBF of the unit is greatly improved over conventional designs, according to the company. Large design headroom, full electronic protection and 5000 VDC input to output isolation also contribute to the long operating life of the unit. All heat generating components are installed on aluminum heat-sink blocks which are cooled via baseplate to a heat-sinking surface and by natural convection. The DHR 150-24 delivers the full 150W continuous output power over an extended temperature range from 0ºC to +70ºC, with no derating.
