Digital rectifiers with forced cooling AC/DC Scr bridge RDC

Power supply systems for industrial environments

RDC, the battery charging rectifier, is an energy converter for industrial use designed to ensure a constant power supply in association with the batteries. Using different types of connections and operating criteria, and building on the experience gained in the last 40 years, our partner can fulfil any request while ensuring a high system efficiency. The series of rectifiers and battery chargers for industrial use is based on total control 6- or 12-pulse thyristor bridges. We can supply a wide range of systems with voltage output from 24 V DC to 220 V DC and current output up to 1000 A. The equipment is installed inside stand-alone, self-supporting cabinets. The frame and the panels are made of steel. The protection degree is IP 30 (up to IP42 upon request) and IP 20 when the panels are open; access to the equipment is from the front. The equipment is designed, manufactured and tested in compliance with the applicable IEC regulations.
