Spd Type 2 Surge Protection Device Multi Functional Overvoltage Protection

Electrical equipment power system surge suppressor dehn spd

Product description

Surge protector is a lightning protection measure adopted for the circuit system. The important performance of internal lightning protection is suitable for household housing, the third industry and industrial equipment, so that it is free from overvoltage damage such as inductive lightning and electrostatic discharge introduced by the system.
After the special process is processed to avoid the signal interference, the multistage protection circuit is adopted, which has the advantages of small insertion loss, fast response speed, accurate clamping and low output pressure.

Product specifications

Notice of product

1.The PE line of the lightning arrester must be reliably connected with the ground wire of the lightning protection system, and the connection line is short, thick and straight.

2. lightning arresters are connected in series

3. ambient air temperature is no more than +40 C and no less than -5 C, and the average value of 24 hours is no more than +35 C.

4. lightning protector should be regularly tested during operation. If there is any failure, it should be maintained or replaced in time to ensure equipment safety.

Working principle of product

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. Then, surge protector rapidly changes to high resistance state, so that normal power supply is not affected.
