The OPUS Inverter system is a redundant, fault tolerant system. Inverter system is an optimal solution when long autonomy time and long battery service life are required. Inverter system is compatible with several battery configurations. Inverter system fits in the standard 19″ racks and cabinets. DUAL inverters efficiencies are high, up to 90%.

The OPUS Inverter system has a modular construction. The inverter modules can be combined with static switch, manual bypass, AC distribution and 3-phase synchronization modules based on customer’s needs.Additional integration options include the advanced VIDI+ controller, temperature sensors and battery monitoring.

Relay alarms
Relay alarms 2 relay contacts:
Fault in system summary alarm (module failure, DC input low etc)
Primary supply failure (system with bypass) or Output ON indication (system without bypass)
Remote monitoring through RS-232 (Remote monitoring software) Status information: For example input and output voltage, power, temperature, faults etc Parameter adjustment: For example input voltage limits, output volt- age, over load, faults etc.
