If you have been using your electronic devices without a TV guard in your house, then you are taking a very big risk with your money. As you can see the capacitor exploded because it could not handle a power surge and the contents spewed out from the top. On top of that the fuse had blown, all the rectifying diodes and the main processor were damaged too. Below is what a power surge did to a 32 Inch TV. Dont worry because all these problems can be avoided simply by using a Voltage guard.

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.

​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.

Solar Lighting System is the best known as a method for generating electric power by using solar cells packaged in photovoltaic modules, photons from sunlight knock electrons into a higher state of energy, creating electricity. Photovoltaic denotes the unbiased operating mode of photodiode in which current through the device is entirely due to the transduced light energy. Solar cells produce direct current electricity from light, which can be used to power equipment or to recharge a battery.

The voltage monitor is a product which can protect electrical equipment from abnormal power supply. The product monitors the supply voltage constantly, and if the power supply is abnormal, the product wil lcut-off the power supply.

Both products are used as protectors, so what is the difference between them？This article aims to explore the differences and help customers better understand this two products.
