The IOTA ILB CP05 A constant power emergency LED driver enables the existing LED fixture to deliver emergency illumination for 90 minutes in the event of a loss of normal power. The ILB CP05 A delivers 5 watts of constant power while in the emergency mode, resulting in no degradation of the emergency lighting for the entire runtime. The ILB CP05 A wires in conjunction with existing AC driver and LED array and features a forward voltage range of 10-60VDC to ensure compatibility with most any Class 2 LED luminaire. IOTA Constant Power Emergency LED Drivers allow commercial spaces to use their existing fixtures to deliver code-required emergency egress illumination, eliminating the need for additional/unwanted wall-mounted emergency lighting units. IOTA.s patented constant power design makes it easy to determine actual emergency lumen levels . simply multiply the emergency driver.s output wattage by your fixture.s .efficacy. (ie. lumens per watt.) Additionally, the auto-sensing 10-60VDC forward voltage of the IOTA emergency driver automatically detects the needed voltage required by your fixture.s Class 2 (0-60VDC) LED component to provide confident system compatibility. Universal 120-277VAC input. The galvanized steel construction with wiring enclosed in dual 24 in. flexible conduit is suitable for plenum, non-air handling ceilings. Includes single-piece test switch/charge indicator accessory. UL Listed for factory or field installation.
