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.

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.
