Feature: 1. Single‑phase circuit will automatically cut off when over‑voltage or over‑current fault occurs, and automatically return to normal. 2. When the line appears transient overvoltage, the protection does not produce malfunction. 3. The protector itself will not be damaged when the line has voltage instability or sudden power failure and sudden incoming power. 4. When the line fault voltage is the highest, the protector itself will not be damaged. 5. The overvoltage value, undervoltage value, overcurrent value and delay value can be set by themselves, and can be adjusted according to the actual situation. Specification: Item Type: Overvoltage Protector Material: ABS shell Model: SVP-918 Rated Voltage: 230V Frequency: 50HZ Rated Current: 1A-40A adjustable (default 40A) Undervoltage Action Cut-off Value: 210V-140V adjustable (default 160V) Overvoltage Action Cut-off Value: 230V-300V adjustable (default 280V) Power Delay After Failure: 5s Delay Range: 1s-600s adjustable (default 30 seconds) Electrical Machinery Life: ≥50000 times The over-voltage and under-voltage action recovery value is 5V of the set value, and the over-current recovery value is less than the set value 1A. Purpose: The intelligent over-voltage, under-voltage, over-current reclosing protector is a comprehensive intelligent protector integrating over-voltage protection, under-voltage protection, and over-current protection. When an over-voltage fault, under-voltage fault, or over-current fault occurs in the line, This product can cut off the power instantly to protect electrical equipment from being burned. When the line returns to normal, the protector can automatically restore power. The overvoltage, undervoltage, overcurrent, and delay values of this product can be set by themselves, and the corresponding parameters can be adjusted according to the actual situation of the user. . Package List: 1 x Overvoltage Protector1 x English User Manual Note: Correctly wire the input and output terminals according to the product label. (The load current should be less than the protection current value of the product)Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
