Understand Voltage Protectors

Voltage protector is a device used to protect electronic equipment from voltage fluctuations and transient impact damage. It usually cuts off power supply when the voltage is too high or too low, or guides surge voltage to ground through components such as varistors and TVS diodes to ensure that the equipment is not damaged by voltage spikes.

Voltage protectors are very common, and most households and offices have connected power protectors. Why?

Firstly, in special circumstances, power grid switching and starting large electrical appliances can cause instantaneous voltage spikes. Without protection, they may be directly destroyed.

Secondly, even with small currents present, absorbing them through voltage protectors can significantly increase the lifespan of the equipment. Compared to the high cost of repairing or replacing damaged equipment, the protector itself is cheaper.

how to choose voltage protector

Choose according to the location you are using, and first check the Joule capacity. It is recommended to have at least 1000 J or more, with higher values being more durable; Choose models with "protection indicator light", "sound and light alarm" or remote monitoring function for more peace of mind.
