Product Overview

The 125VDC system uses latest Rectifier / Controller technology to support 125V DC loads with low output noise emissions & ripple content. It offers high power density albeit using a lower foot print. 125VDC power systems are highly reliable and can be configured depending on the customer’s requirements. 125VDC’s power system design imparts flexibility to perform in a heavy Industrial environment.

A typical 125VDC system comprises a number of rectifiers, depending on the power requirement, a controller and power distribution panels (AC or/and DC). In addition, inverters & converters can be incorporated in a single cabinet to provide an effective and totally integrated power system.
