Description

The RPA20-AW series are high power density, wide input voltage range 20W DC/DC converters in an industry standard 1”x1” case size. Despite their small size, the RPA20-AW converters are fully specified devices with output currents up to 6Amps, up to 88% efficiency, no minimum load, 1600VDC isolation, tight regulation and low ripple/noise figures. The outputs are also fully protected against over-temperature, short circuits, overcurrent and overvoltage and the single output version offers a ±10% trim range. A heatsink option is available to extend the operating temperature range. The converters are UL and EN50155 pending and will find many uses irailway and industrial applications where board space is at a premium.
