General

Unit Information

The Defender 1 is an Emergency Lighting Inverter System incorporating double-conversion

technology. It provides perfect protection specifically for Egress Lighting for facilities.

The inverter is a double-conversion principle eliminates all sources of power disturbances. A rectifier

converts the alternating current from the building source to Direct Current (DC). This DC charges the

batteries and powers the inverter. With the basic DC voltage, the inverter generates a sinusoidal

alternating current (AC) voltage, which continuously supplies the load.

The load is powered by the inverter, which receives its power from the building source. In the event

of the loss of the building source power the inverter will then derive it’s power from the batteries.

All units come standard with a 90-minute backup time.
