Voltage control relays are designed to protect devices with sensitive operating voltage values from failures that may be caused by mains voltage.
Usage and Working Principle
Make the connections of the device in accordance with connection scheme. Set the required settings of the device according to the operating voltage values of te load. When the device is energized, if the voltage values are normal according to the set values, the relay gets activated and the relay LED(≠) is turned on. When the voltage values go out of the set values, the related fault LED is on, it waits until the delay time (DT), after the time has elapsed, the relay gets de-activated and the relay LED goes out. When the voltages return to their normal values, the device waits until the reset time (RT), after the time has elapsed the relay gets activated and the relay LED is turned on.
