Description

The RPA120H series are high power, 110VDC wide input range 120W DC/DC converters in an industry standard half brick format. Despite their low cost, the RPA120H converters are fully specified devices with output currents up to 8.3Amps, up to 88.5% efficiency, no minimum load, 3kVDC isolation, tight regulation and low ripple/noise figures. The trimmable outputs are also fully protected against over-temperature, short circuits, overcurrent and overvoltage. The converters are UL and EN50155 pending and will find many uses in cost sensitive railway and industrial applications.

The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary; they also can be calculated with below shown equation.
