S Series (DC-DC)

The ER/HR Series of DC-DC converters represents versatile power supplies ideally suitable for use in transportation and other advanced electronic systems. The HR Series converters include a very broad input voltage range, very high efficiency, high reliability, low output voltage noise, and excellent dynamic response to load/line changes. HR converters can be connected to all conventional railway batteries. ER Series converters are optimized for connection to 110 V railway batteries.

Like all of the Bel Power Solutions cassette series, the S line features high efficiency, high reliability, low output voltage noise and excellent dynamic response to load/line changes, with its very wide input voltage ranges of 8 to 385 VDC. They offer input over and undervoltage lockout, along with adjustable output voltage with remote on/off.
