1.General Introduction
General Introduction
The automatic over-voltage and under-voltage delay protector is a new generation product developed by our company according to market needs. The protector is reasonably designed and assembled with imported components and domestic famous-brand components. It adopts advanced manufacturing methods. The product can quickly and reliably cut off the power supply under high-voltage shock and under-voltage conditions to protect household appliances. When the voltage returns to the normal value, the circuit can be automatically turned on and the power supply will be restored after delay, which can effectively protect the electrical appliances from the impact of the power supply momentarily. All functions are fully automated with no special person operation is required.Two-color light-emitting diodes are selected. The power indicator is green and the protection indicator is red.

3. Installation and Dimension
4. Precautions
4.1 When the power supply of the product is normal, the first time the input terminal is connected to the power supply requires a delay time of less than 1 minute before the product is powered on.
4.2 When the protector enters the protection state when the voltage is abnormal, the internal relay has only one set of contacts to cut off the live line. Installation must be correctly connected to the neutral line N and the phase line and the phase line L, otherwise the load is live.
4.3 After the product is connected to the power supply, do not touch the live parts to avoid electric shock.
4.4 Be sure to tighten the terminal screws when wiring, otherwise the terminal will trigger heat due to poor contact and cause damage to the product or cause other accidents.
