Zener iZen Inverter 3/3 Phase 10 kVA to 90 kVA

The ZENER 3/3 Phase 10kVA to 90kVA range of Pure Sinewave iZen Inverter/ Emergency Power System (EPS) utilize state-of-art Microcontroller technology for the supply of emergency electrical power that instantaneously supports essential but non critical electrical systems on loss of normal power supply. The standby power system includes an inverter and batteries. These emergency power systems are installed to protect life and property from the consequences of unscheduled loss of primary electric power supply.


The iZen range of Emergency Power supply are generator compatible, for flicker free transfer of loads on power failure and resumption and flexible enough to be adopted as UPS for computers and other sensitive equipment.

ZENER Emergency Power Supplies and Inverters find uses in a wide variety of settings from homes, hospitals, scientific laboratories, data centers, telecommunication equipment and commercial buildings.
