Mains failure monitoring
- Energy distribution
- 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
