The ILB CP18 HE CW from IOTA is a UL Listed LED emergency driver that allows the same LED fixture to be used for both normal and emergency operation. In the event of a power failure, the ILB CP18 HE CW switches power from the normal LED driver operate the LEDs in the emergency mode for 90 minutes. The unit includes a charger and converter circuit in a reduced-profile housing and a separate sealed lead acid battery component. The ILB CP18 HE CW will operate an LED array load at 18 watts with constant power at a rated output voltage of 20V-58V. The Constant Power design of the ILB CP18 HE CW maintains the output wattage to the LED array resulting in non-diminishing illumination for the entire runtime. Includes single-piece IP67 rated test switch and charge indicator accessory. The ILB CP18 HE CW features charging control circuitry that allows the battery pack to reach acceptable operating temperatures before reactivating the charging circuit.
