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.

In April，Our company, Wenzhou BXST Co.,ltd, a 12-years' professional manufacturer of VOLTAGE PROTECTOR and VOLTAGE REGULATOR STABILIZER, went to South America, like Dominica, Colombia, Panama, the United States, etc.; at the end of July, we pushed in Southeast Asia. For us, Southeast Asia is a new market. New markets, new challenges, and new opportunities. In the coming September, we will start a new journey to the other side of the globe - Africa. We hope that our new voltage protectors, voltage regulators and solar systems will shine in new markets.

When the current is higher than the limited value, our device automatically cuts off the power, and when current is normal then it will connect to the powe automatically, no need to manual change.

A changeover switch is designed to transfer a house (or business) electricity from the commercial power grid to a local generator when n outage occurs. Also known as “transfer switches,” they connect directly to the generator, commercial power supply or line, and the house. When the homeowner or business owner experiences a power outage, he or she can switch over to the generator via a changeover switch.

On April 15, the first phase of the 125th Spring Canton Fair was grandly opened at Pazhou Complex. Wenzhou BXST Co.,Ltd brings together intelligent electronic products to attract new and old customers from all over the world to come and observe.

​Change Over Switch with high power and four phases in the Middle East market. It can be used for hospitals, hotels, supermarkets and other public places. Under the condition of the frequent power-off, it can be switched automatically to four power supplies without manual change. It applies for the home appliance which rated power is less than 6600W.
