OPUS HE bulk rack is intended for local cabinet system builders. Local builder can use standard building block from Enedo and install it to right type of cabinet with batteries. Bulk rack includes readymade cable connections and parameter settings, which reduces significantly the design and manufacturing costs needed in local system builder side. OPUS HE bulk rack is ideal solution for local partner to increase the flexibility and value provided for local end customers

The new OPUS HE series provides free air convection cooling, N+1 redundancy and is the ideal backup power solution for critical infrastructure applications such as transmission and distribution substations, process industries, railway signaling and substations, and telecommunications.

Key features

OPUS HE bulk rack power system consists of Enedo’s MHE rectifiers, VIDI2 controllers, connections for mains and battery connection with shunt resistor  and bulk screw terminal for external load distribution. Rack building block can be used as 19″ 8U rack module or 5U rectifier shelf and 3U control panel can installed to different position in cabinet. The system delivers a maximum 10 kW output power at 48, 60, 110, 125 and 220 VDC, and 7.5 kW at 24 VDC output. The base system supports up to five (5) MHE series high efficiency rectifiers, but may be expanded by using the Slave Rack in a master-slave configuration, increasing the power capability to 64 kW in multi cabinet configuration.
