The RLH 500 Series Rack Mount DC/DC Converter is an isolated DC power source designed to provide constant power to telecom and industrial equipment. There are several models available, rated up to 30A. They feature recessed front panel input power circuit breakers and a digital ammeter for monitoring the output current.

The converters have dual inputs with automatic internal switching for connecting redundant power input sources, and three position output terminals for connecting multiple devices. Each input is protected by heavy duty circuit breakers.

The Series 500 DC/DC converter is an EIA 19/23 inch 2RU rack mountable enclosure, with both front or telco center style rack ear mounting.

It is recommended that a power breaker placed before the DC/DC converter for applying and removing power to the unit be rated at 1.5 times the current of the DC/DC converter being used. Please refer to the product data sheet for additional information.
