Features Regulated Converters * * * * * * 4:1 Wide Input Voltage Range 1.6kVDC Isolation UL, IEC/EN and EN50155 Certified Efficiency Up To 89% OVP, OCP & OTP +105C max Case Temperature DC/DC Converter RPA30-AW Description 30 Watt 3 1"x1" Single & Dual Output 3Y The RPA30-AW series are high power density, wide input voltage range 30W DC/DC converters in an industry standard 1"x1" case size. Despite their small size, the RPA30-AW converters are fully specified devices with output currents up to 7.5Amps, up to 89% 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 certified and will find many uses in railway and industrial applications where board space is at a premium. wa EAR rranty Selection Guide Part Number RPA30-243.3SAW(2,3) RPA30-2405SAW(2,3) RPA30-2412SAW(2,3) RPA30-2415SAW(2,3) RPA30-2412DAW(2,3) RPA30-2415DAW(2,3) Input Voltage Range [VDC] 9-36 9-36 9-36 9-36 9-36 9-36 Output Voltage [VDC] 3.3 5 12 15 12 15 Output Current [mA] 7500 6000 2500 2000 1250 1000 Input(1) Efficiency(1) Current typ.
