OPUS C 12U

Modular Battery Charger

OPUS C 12U are compact, 19″ rack-mount DC power systems that offer a robust, free convection cooled, N+1 redundant backup power solution for telecommunications, process industry, transmission and distribution substations and other critical infrastructure applications.

The OPUS C 12U is a 19″ self-contained rack-mount power system consisting of the MRC series rectifiers, VIDI+ controllers, mains and battery connections, and a wide selection of load distribution options. OPUS C systems are available in 24, 48, 60, 110, 125 and 220 VDC standard outputs and have a max output power of 8.0 kW.The systems meet IEC 60950-1 safety standards and the following EMC standards: Emissions: IEC/EN 61000-6-4, Immunity: IEC/EN 61000-6-2, Harmonics: IEC/EN 61000-3-2, and Voltage Fluctuations & Flicker: IEC/EN 61000-3-3.

The OPUS system can be connected to 3-phase TN, TT or IT power distribution systems. The nominal operating voltage of the system is 3*230/400 Vac, 50 Hz.
