Volt Guard | Manual Voltage Stabilizer Auto Cut Off Circuit Board

This circuit board is designed for volt guard and manual stabilizer.
To run this board we need 15v Step Down Transformer.When the AC main line is 220 volts, Transformer's output is 15v. When the AC voltage increases to 260v, transformer secondary voltage also increases, 1k preset is set at this voltage so that relay switches turns off.And also, when AC voltage decreases, output voltage of transformer also decreases. which is about 9v to 10 volts.At this voltage,Relay automatically turns off.We can set 1k resistor for low voltage cut off.This board protects any device in two steps.
