Inverters (ac power inverters, battery chargers, power supplies) |Emergency lighting|Egress lighting|manufacturer emergency lighting|Industrial lighting During normal operation, when unswitched AC is present, the fixture will be fully illuminated by means of the regular ballast. At the same time, the emergency ballast is supplied with AC, which transforms and rectifies into a low DC voltage to recharge the battery and maintains it in a fully charged condition. When the AC fails, a solid state voltage senor instantly turns on a high frequency inverter which illuminates one or two* lamps in the fixture for a minimum of 90 minutes. At the end of the rated time a low voltage sensor disconnects the battery to prevent over-discharging. When the AC returns, the inverter switches off and the battery begins to recharge. *Available in FPS-T only, can run 2 lamps in a 2 or 4 lamp fixture.All metal construction with white baked enamel finish and 3" pre-wired fixture whip.
