Purpose and Scope of Application

The fully automatic overvoltage and undervoltage delay protector is a new generation product developed by our company according to market demand. The protector is designed reasonably and assembled with imported components and domestic famous brand components, using advanced manufacturing techniques. The product can quickly and reliably cut off the power supply under high voltage impact and undervoltage conditions, protecting household appliances. When the voltage returns to normal, after a delay, it can automatically connect the circuit and restore power supply, effectively protecting appliances from the impact of momentary power on. All functions are fully automated, without the need for dedicated personnel to operate, and dual color light-emitting diodes are used for indication.
Power indicator: green protection indicator: red

Instructions

1. Connect the input (in) and output (out) terminals correctly according to the product identification (the load power should be less than the rated power of the product).
2. The two light-emitting tubes on the product panel indicate the status: when the power is turned on, the power indicator light (green) is on, and when the power is supplied normally, the protection indicator light (red) is not on; When in the protection state, the protection indicator light (red) lights up, the protection function is activated, and the load power supply is cut off.

Matters needing attention

When the input terminal is powered on for the first time during normal power supply, a delay time (<1 minute) is required for the product to be powered on.
When this protector enters the protection state due to abnormal voltage, the internal relay only has one set of contacts to cut off the live wire. It is necessary to correctly connect the neutral wire (N) and the phase wire (live wire L) during installation, otherwise the load will be charged.
3. After the product is powered on, do not touch live parts to avoid electric shock.
4. When wiring, be sure to tighten the screw at the end of the wire, otherwise poor contact may cause heating at the terminal and damage the product or cause other accidents.
