Three UPS Systems designed with best micro controlled devices and Hybrid Circuits device Pure sine-wave clean Power under all operating conditions.

On-line Double Conversion

We are constructed on Ture OnLine Architecture continuously supplying critical connected load with a stable clean and pure sine wave power.

Advanced Vector Control

We use latest vector control Technique at the Input of the UPS. This technology is now globally adopted for optimum energy consumption and phenomenal reduction of UPS current demand all the input.

Major Application

IGBT Based Inverter & Smart Charger

High Switching Frequency for maximum system efficiency, minimum harmonics, fast transit responseand increased better life.

Digital Signal Processing

We are fully Digital adopting a Single ProcessingUnit that integrated all power stages as well ascontrol functions. The systems uses only 4 cards ascompared to a large number of control card inconventional UPS System. Single Processing Unitincreases system availability through increasesreliability.

Isolation Transformer For Grounding Problems

All VIRDI models incorporate Isolation Transformerat the output of the UPS to attenuate problems arising out of poor input ground- ing and leakage voltage in neutral.
Optional Add Ons include SNMP Network Protocol, RS-232 com- munication Port, Wall-mounted Remote Monitoring Panel (RMP)- Matching Battery Cabinets
