VIDI+ System Controllers

VIDI Controller Platform is a powerful tool to set ideal parameters and monitoring architecture for OPUS backup power systems. True redundancy principle applies also for the controller, which means that controller can be changed or updated without any power break in the system. The controller has intelligent and easy to use local interface and web access to monitor the system behaviour and plan the controlled maintenance process during the expected 15-20 year life time of the power system.

The system has diagnostics for the battery health and expected battery lifetime, which typically defines the timing for the modernization investment. On top of default power system features included in main VIDI, additional features can be added by auxiliary VIDI controllers. Such aux controllers are VIDI-BM battery block voltage monitoring, VIDI-LVD additional LVD driver, VIDISAM inverter controller and IEC61850 converter for SCADA networks.
