Despite their small size, the RPA20-AW converters 1 x 1 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 Single and Dual 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. Output The converters are UL and EN50155 certified and will find many uses in railway and industrial applications where board space is at a premium.
