PM80 - DC/DC Industrial Converter

Product Overview


POLYAMP  DC/DC Industrial Converters

Polyamp provide free standing DC/DC converters, which means they meet EMC, EMI, electrical safety requirements and can be installed in any weather protected environment. The units are air cooled, convection cooled and can mostly be mounted in any direction.

The EMC performance is such they can be mounted in low noise applications. The output ripple is among the industries lowest. The immunity levels meet tough requirements in substations, trains, vehicles, railway and industrial applications. We have also models that meet EN50022 special low noise Telecom environment.

The mechanics are based on sturdy aluminum cases, that provides conduction cooling, mechanical stability for any type of vehicles, trains, locos, ships, marine, military rubber wheel vehicles. All units can be mounted on chassis, mounting plate, wall also with TS35 DIN rail. Most units are 19"-rack modular 2U, 3U, 6U.

Polyamp can provide special mechanics solution and systems based on our units, as well as Secure 2x N+1 redundant systems for power utilities, off shore applications and many more.

Polyamp production system is ISO9001:2008 certified.
