under-voltage protections, over-current protections and integrated intelligent protector. When there is over-voltage, under-voltage and over-current solid barriers in the line, this product can instantly cut off the circuit, avoiding damage to electrical equipment. When the unnecessary circuit returns to normal, the protector can automatically restore the circuit to make the electrical equipment work normally. The overvoltage value, undervoltage value, overcurrent value, circuit recovery time value and overcurrent protections reset time value of this product can be set by themselves. Adjust the corresponding parameters according to local actual conditions and electrical usage conditions. Note: The line voltage should not be higher than 330VAC to prevents the product itself from being damaged due to excessive voltage. Please contact the manufacturer if a high power supplys is required in a specific situation.
