Our Advantages1.General IntroductionThe 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. 2. Main technical
