Dual-Lite® UFO-3AW Fluorescent Lamp Emergency Lighting Battery Pack, 120/277 VAC

UFO-3AW emergency fluorescent battery packs are designed to provide a minimum of 90 minutes of emergency lighting to one lamp in 2-4 foot commercial or industrial fixtures. Operation is fully automatic. A solid-state charger maintains the battery at full charge as long as utility power is present. Upon interruption of normal power, the unit will activate and the automatic transfer circuit will switch to the emergency mode, keeping one lamp illuminated at a reduced lumen output for a minimum of 90 minutes. Upon restoration of normal power, the emergency battery pack returns to the charging mode and delays AC ballast operation for approximately three seconds to prevent false tripping of AC ballast (end-of-lamp-life) shutdown circuits. Full battery recharge is accomplished within 24 hours. A test switch and LED charge indicator light is provided with all models for testing and monitoring of unit performance. Dual input allows operation from either 120 or 277VAC, 60Hz.
