At present the latest model of the protection of power supply L-N,L-PE,N-PE dedicated ccmodule from my company successfully into the market, is currently the highest-the ratio of price and performance lightningproof module. Other types of lightningproof module provide only common model protection, such as when lightning strikes occur ,the module may cause damage.
According to the Leidianfanghu power available to the urgent need, we developed a novel lightningproof modular for power supply, it belongs to the intellective device, and provides better protection for power supply, electromagnetic compatibility characteristics also higher. It has a delicate frames, thermal disengagement button set within,technologically-advanced, user-friendly, economical and practical, protective functions strong, broad scope of application, with independent intellectual property rights. It used to the entire protective circuit and "3+1" circuit, applies particularly to lightningproof protection for the power supply of CATV amplifier.
in the normal work situation, the lightningproof component within lightning arrester is in the high impedance state. When unexpected over-voltage, over current and thunderbolt occurs, lightningproof component will switch on rapidly, and over-voltage, over-current and thunderbolt invasion wave will be limited to the permitted extent for electricity equipment, thereby protects the power supply to run normally. The Lightning protector also has the operation instruction LED,it is easy to inspect the state of the Lightning protector.
