Single Phase Undervoltage Relay 3 LEDs For Status Indication 440VAC SVRD-220
1 , over-voltage protection: When the grid voltage is greater than the set value starts the protection function, the action threshold setting range OFF-390-490V, action mode is definite time, action time setting range 0.1-25s. After the protection action, the grid voltage returns to less than the set value of 10V or more.
2 . Undervoltage protection: When the grid voltage is lower than the set value, it starts the protection function, the action threshold setting range is 300-370V-OFF, the action mode is the definite time limit, and the action time setting range is 0.1-25s. After the protection action, the grid voltage returns to more than 10 V above the set value.
