General
Unit Information
The Defender 3 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 three-phase unit that 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.
