Unstable voltage can cause fatal injuries or malfunctions to equipment, affect production, and cause many losses such as delivery delays and unstable quality. In serious cases, safety accidents may even occur, causing immeasurable losses.
The original power voltage stabilizer relied on the beating of a relay to stabilize the voltage. When the grid voltage fluctuates, the automatic correction circuit of the power regulator activates, causing the internal relay to operate. The advantage of this circuit is that it is simple to force the output voltage to remain near the set value. The disadvantage is that the voltage stabilization accuracy is not high and every time the relay jumps and shifts, the power supply will be momentarily interrupted and spark interference will occur.
