OPUS HE 7U Up to 6KW

Convection Cooled – Modular Battery Charger For Industrial Applications

The new OPUS HE 7U is a high-efficiency rack-mount DC power system that is designed for critical infrastructure applications such as telecommunications, process industries, railway signalling and substations, and transmission and distribution substations.OPUS HE DC power systems consist of MHE rectifiers, VIDI+ controllers, Connections for mains and battery and load distribution. System is configurable to match with requirements of the application.

19” 7U Rack delivers maximum 6 kW output power at 48, 60, 110, 125 and 220 VDC and 4.5 kW at 24 VDC output. 19” 7U Racks include slots for maximum 3 rectifier modules, battery breakers and shunt for one string and bulk DC load output. Wall mounting, IP21 cover kit, temperature sensor, battery block voltage monitoring and BLVD are options. Master-slave set-up can be used to increase power higher than 6kW. The base system supports up to three (3) MHE series high-efficiency rectifiers, but may be expanded by using the 7U Slave rack in a master-slave configuration, increasing the power capability to 16 kW.
