IOTA ILB-CP05 Emergency Driver LED Operation
20 Watt LED load @ 20-60 Vdc Nominal*

20 Watts (Constant)

Emergency Operation
90 Minutes

Product Description

The ILB-CP20-HE from IOTA Engineering is a UL Listed LED emergency driver for field or factory installation that allows the same LED fixture to be used for both normal and emergency operation. In the event of a power failure, the ILB-CP20-HE switches to the emergency mode and operates the existing fixture for 90 minutes. The unit contains a battery, charger, and converter circuit in a single enclosure and is available in different mounting configurations for individual fixture requirements. The ILB-CP20-HE will operate an LED array load at 20 watts with constant power at a rated output voltage of 20-60V. The patented Constant Power design of the ILB-CP20-HE maintains the output wattage to the LED array even as the system voltage diminishes, resulting in a constant illumination level for the entire emergency runtime. The ILB-CP20-HE features high-efficiency performance and complies with CEC efficiency requirements.
