Monitoring emergency lighting system
An undervoltage monitoring relay with a fixed switching threshold at 0.85% of the nominal voltage is needed for emergency lighting systems. Two changeover contacts are wanted for signalling.
This device was used because it fulfils the VDE 0100-718 and VDE 0108-100 standards and is equipped with 2 changeover contacts.
