The wide range of input voltages in railway systems means three different versions of the same design are used to cover all of the input voltages from 24VDC up to 110VDC. The RPA100H-RUW and RPA200H-RUW ultra-wide input voltage railway converters now allow an all-in-one solution. The 10:1 input voltage range accommodates all standard input voltages of 24V, 36V, 48V, 72V, 96V and 110VDC in a single unit, including all of the EN50155 transient limits.
The converters are now available with 12V, 15V, 24V or 48V outputs to power a broader selection of rolling stock and high voltage battery applications for mobile industrial equipment. The converters have a consistently high efficiency over the entire 10:1 input voltage range and operate over a wide operating temperature range from -40°C to +93.5°C (when baseplate cooled). The case is fitted with threaded inserts to allow secure mounting to the PCB or bulkhead for use in high shock and vibration environments. They are certified to CE and UL/IEC/EN 60950 and come with a three year warranty.
Samples are available from all authorized distributors.
