RP240H-RW
Description
240 Watt
Half Brick
Single Output
The half-brick RP240H series DC/DC converters are designed for railway rolling stock and high voltage battery
applications. Each series has three 4:1 input voltage range options to cover all input voltages from 9VDC up to
160VDC with isolated and regulated 5V to 48VDC outputs. The converters have high efficiencies and metal base-
plates to permit a wide operating temperature range from -40°C to +85°C (when mounted on a suitable heatsink).
The case is fitted with threaded inserts to allow secure mounting to the PCB or bulkhead for use in high shock
and vibration environments. The converters are EN50155, UL60950 and IEC/EN60950 certified. The RP240H-RW
series have a three year warranty.
