The LEM08 emergency LED driver enables the lighting fixture to deliver a minimum of 90 minutes of illumination during a loss of normal AC power. It is UL listed for factory or field installation with indoor, damp location luminaries utilizing 20-50VDC output voltage. When normal AC power fails, the LEM08 immediately drives the LED load at the reduced light output for a minimum of 90 minutes. When AC power is present, the emergency LED driver ensures the sealed, maintenance-free, high-temperature nickel-cadmium batteries are fully charged within 24 hours after a discharge and remains fully charged until the next loss of AC power. The included test switch/pilot light provides visual and manual means of monitoring the system operation.
