Description

The RPR50 series DC/DC converters are designed for railway rolling stock applications. Besides covering all

the input voltages from 40VDC up to 160VDC, the converters have a very wide operating temperature range

of -45°C to +115°C. The RPR50 has a baseplate case for high vibration or bulkhead-mounting applications.

It is EN-50155 and EN-50121-3-2 certified.

* ICE Technology

ICE (Innovation in Converter Excellence)

uses state-of-the-art techniques to minimise

internal power dissipation and to increase

the internal temperature limits to extend the

ambient operating temperature range to the

maximum.
