High input/output isolation
Conduction/convection cooled
Operation up to 70ºC
Full electronic protection
Customized versions available

This rugged, industrial quality AC/DC power supply with PFC input is designed for an operating life extending to 30 years. By
eliminating opto-couplers in the feedback loop and significantly reducing the component count, the MTBF of the unit is greatly
improved over conventional designs. 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. Conformal coating provides additional environmental
protection. Large design headroom and the use of components with established reliability also contribute to the long operating
life of the unit. Customized versions are available. The unit is manufactured at our plant under strict quality control.
