Emergency LED Driver, 100-347V AC Input, 170V DC Output, 90-Minute Li-Ion Backup

An emergency LED driver for panel, troffer, linear and high-bay LED luminaires listed for dry and damp locations. On loss of normal AC power, the unit transfers the fixture to battery operation to maintain egress illumination, and returns it to normal operation when utility power is restored. The driver accepts an unswitched 100-347V AC, 50/60 Hz input at 0.1 A maximum and delivers 170V DC at 15 W in emergency mode for a 90-minute rated runtime from a Li-ion battery pack. It supports 0-10V dimmable fixtures up to 100W under normal operation, with an ambient range of 5°C to 50°C and a maximum mounting height of 27.2 ft. An integrated test switch verifies emergency function; initial commissioning requires a charge cycle greater than 24 hours to activate all battery cells. UL listed under file number E493915. Backed by a 5-year warranty.
