Voltage Protection Guide

This paper introduces the necessity of using household voltage regulator.

This paper introduces the function difference and working principle of voltage protector and surge protector.

The function of the household voltage regulator is to stabilize the power supply voltage required by the large fluctuation and the unsuitable electrical equipment within its set value, so that various circuits or electrical equipment can work normally under the rated working voltage.

Stabilization is a product with the best comprehensive technical performance, highest reliability and lowest maintenance cost among various technical types of AC regulated power supplies.​

The voltage protector is a smart household product, which can also be called over-voltage protection device. Its principle is to effectively protect the household appliances by using the voltage range set by the internal MCU program.

Since some electric appliances contain coil components, eddy currents that hinder current flow are generated at the initial stage of energization. The generation of eddy currents weakens the instantaneous voltage at the start of the electric appliance, resulting in slow start-up, and strengthens the instantaneous voltage generated after the disconnection, which may cause spark damage. Circuit. A voltage regulator is needed to protect the proper operation of the circuit. The voltage regulator is composed of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate, so that the position of the voltage brush of the voltage regulator changes. The output voltage is kept stable by automatically adjusting the turns ratio of the coil. The larger capacity regulator also works on the principle of voltage compensation.

The circuit often generates high operating overvoltages when struck by lightning and when switching on or off inductive loads or large loads. This transient overvoltage (or overcurrent) is called surge voltage (or surge current).

This article is a review of the newly released item by BXST called Voltage Protector. It is co-related with the more familiar Automatic Voltage Regulator (AVR) item because of its primary function to protect appliances. A Voltage Protector guarantees us the same protection in the case of an over-voltage or an under-voltage.
