Voltage measuring and monitoring relay
250 V, 2 VA | E18 F77
FIBER
Under voltage monitoring relay with fixed voltage threshold and adjustable response time (17.5 mm)
Single-voltage
Microcontroller electronic device, with supply voltage from 170Vac(operating threshold) to 230Vac 50 and 60Hz
It controls the supply voltage and it starts operating when the value is less than 170Vac (75% of 230Vac)
If the voltage falls below 75% of the nominal supply (under voltage) for more than 100mS, the device will de-energize the relay
The device will remain in this state until the mains supply voltage rises above 75% of the nominal supply for a time period of more than the time set by potentiometer placed on the front panel (5-15 min)
