OPUS HE OC2066 DC Power System

Modular Backup Power Solutions for Critical Infrastructure

OPUS HE power systems are robust, free convection cooled, N+1 redundant backup power solutions for critical infrastructure applications such as transmission and distribution substations, process industries, railway signalling and substations and telecommunications.

OPUS HE power systems are robust backup power systems that deliver from 2 – 24 kW of output power at 48V, 60V, 110V, 125V and 220VDC, and from 1.5 – 18 kW at 24VDC output. The cabinets have standard configurations for 3, 6 or 12 MHE rectifier modules, VIDI+ controllers, connections for mains and battery, and load distribution fuses or MCBs.

Systems can easily be tailored to match unique application requirements by changing the quantity of rectifiers, battery fuses, battery shelves, load distribution and many other features. In addition to 12 configurable relay alarms, systems can be remotely monitored via modern communication protocols such as Ethernet TCP/IP, Modbus TCP/IP, SCADA IEC61850, SNMP and RS-232.
