Alternating current electric power surge protector for AC power
Product Details
Surge protector, designed and manufactured according to IEC and GB standards, meets IEEE802.3AT requirements and is suitable for power surge protection in home, third industry and industrial equipment. A lightning protection product is specially developed for equipment surge to avoid inductive lightning and electrostatic discharge introduced by the system. Overvoltage damage. It has the characteristics of low residual pressure level, sensitive reaction, stable performance and reliable operation.
Working principle of product
The power surge protector is divided into two parts: explosion proof box type and modular type. A varistor with excellent nonlinear characteristics is adopted. Under normal conditions, the surge protector is in extremely high resistance state, and the leakage current is almost zero, thus ensuring the normal power supply of the power supply system. When the power system surge overvoltage, the power surge protector immediately passes in the nanosecond time, limits the amplitude of the overvoltage to the safe working range of the equipment, and releases the surge energy into the ground. Subsequently, surge protector rapidly changes to high resistance state, so that normal power supply is not affected.
Product features
1. Small leakage current, quick response time, low residual pressure
2. new technology, high energy, gap discharge electrode N-PE..
3. detachable assembly and pluggable convenience

Use of attention
1. when the current carrying conductor is part of the closed loop, the circuit and the induced voltage decrease as the conductor approaches the circuit.
2. the connection requirements of more than 2.5mm2; when the length of more than 0.5 meters of more than 4mm2.
3. when installing, pay attention to the cable entering and leaving the surge protector. The cables should be separated to avoid the two coupling of surge.
