The RG40 is a solid-state, DC to DC switch-mode converter that converts an input DC voltage (27.5 VDC nominal) to a regulated 13.75 VDC output voltage. The RG40 meets the Federal Aviation Administration (FAA) technical standard order TSO-C71 (airborne static DC to DC electrical power converter - for air carrier aircraft).Two or more RG40's may be paralleled (external diodes required) if additional power is required.
