Voltage monitoring 3-phase against N, Voltage failure monitoring, 400V, 2 CO, fixed threshold voltage Us=195,5V
Monitoring relays - ENYA series Undervoltage monitoring Supply voltage = measured voltage 2 change over contacts Width 35 mm Installation design Task The emergency lighting is activated in the event of a mains failure or undervoltage. Solution 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. Use/value Detects mains failure Applications Emergency Power Facility Management Renewable Energy
