The IOTA ILBLP CP20 HE SD HV is a UL Listed emergency LED driver for field and factory installation that allows a fixture with 55-200VDC Non-Class 2 LED lighting loads to be used for both normal and emergency operation. In the event of a power failure, the ILBLP CP20 HE SD HV 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 with the option of either single or dual flexible conduit for wiring to the fixture and test accessories. The patented Constant Power design of the unit maintains the rated output wattage to the LED array even as the battery voltage diminishes, resulting in a constant illumination level for the entire emergency runtime. Features lithium battery technology for significantly decreased form factor and includes automatic monthly and annual self-testing features as standard. Self-diagnostic status is communicated via the illuminated single-piece test accessory, which can be mounted up to 25 ft. from the unit.
