Features Regulated Converters : Wide input voltage range.6kvdc Isolation UL, IEC/EN69 and EN certified Efficiency up to 88% OVP, OCP & OTP + C max. case temperature Description The RPA-AW series are high power density, wide input voltage range W DC/DC converters in an industry standard x case size. Despite their small size, the RPA-AW converters are fully specified devices with output currents up to 6Amps, up to 88% efficiency, no minimum load, 6VDC 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 ±% trim range. A heatsink option is available to extend the operating temperature range. The converters are UL and EN certified and will find many uses in railway and industrial applications where board space is at a premium.
