VIDI2 HE Systems Controllers

Smart Controller for Modular DC Power Systems from 24  – 240VDC

VIDI2 Controller Platform is powerful tool to set ideal parameters and monitoring architecture for critical OPUS HE backup power systems. True redundancy principle of  OPUS power systems applies also for the controller, which means that controller can be changed or updated without any power break in the system.

Controller has intelligent and easy to use local interface and web access to monitor the system behavior and plan the controlled maintenance process during the expected 15-20 year life time of the power system. System has diagnostics for the battery health and expected battery life time, which typically defines the timing for the modernization investment.

On top of default power system features included in main VIDI2, 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.

Key functions include Energy Save mode, rectifier runtime counter, alarm configuration, real time clock with battery backup, inventory management and more. The VIDI2 controller can support up to 35 rectifier modules.
