Product Overview
The 24VDC system uses latest Rectifier / Controller technology to support 24V DC loads with low output noise emissions & ripple content. It offers high power density albeit using a lower foot print.
24VDC power systems are highly reliable and can be configured depending on the customer’s requirements. 24VDC’s power system design imparts flexibility to perform in a heavy Industrial environment.
A typical 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.
