Mains failure monitoring
The emergency lighting is activated in the event of a mains failure or undervoltage.
The mains failure is monitored with a E3YF400V02 (three phases). If the voltage falls below 85% of the nominal voltage, the output relay trips and turns the emergency lights on.
– Detects mains failure
– Fulfils the VDE 0100-718 and VDE 0108-100 standards
