Description
The Universal Emergency Module (UEM) with Automatic Self-Test (AST) is suitable for class III luminaires with integrated LEDs and separate LED drivers. The DC voltage output is adjusted within the UEM’s limits to the level required to operate the luminaire load and then the current is Limited to ensure an operation time of three hours. This gives a typical power output of 3W but will depend on the characteristics of the luminaire. The UEM can be installed within a luminaire or within the ceiling void. In the event of a power cut the replaceable internal lithium-ion battery will supply the luminaire through a connection that must be made between the LED driver output and LED luminaire input.
