RPA100H-RUW
Description
100 Watt
Half Brick
Single Output
3
The half-brick RPA100H series DC/DC converter is designed for railway rolling stock and high voltage
battery applications. It has a 10:1 input voltage range to cover all input voltages from nominal 24VDC
up to 110VDC in a single product (including EN50155 transients) and offers isolated and regulated
12V, 15V, 24V or 48VDC outputs. The converter has a consistently high efficiency over the entire
input voltage range and comes with a metal baseplate to permit a wide operating temperature range
from -40°C to +97°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.
The converter is certified to UL/IEC/EN60950 and comes with a three year warranty.
