Efficient and reliable, these modular rack mount DC-DC converters allow for easy paralleling of modules to provide redundancy or higher power outputs. Designed for use in modern telecommunications networks these converters offer unrivaled power densities.

The unique design allows for mounting four modules in a 1U x 19” rack or for multiple output solutions they can be integrated into our compact systems and will communicate with an SM series supervisory module for system level monitoring and control.

Plug and Play” installation allows quick and easy installation and system expansion. These robust, reliable converters are forced cooled by a speed controlled and monitored high reliability fan.

Modules are New Zealand made to guarantee design, manufacture and process integrity. Our robust proven conversion topology utilises only highest specification components – unfortunately something rarely offered by others.
