Date:2020-08-12 13:14:28 Views:1840

       Surge protector, also known as lightning protection device, is an electronic device that provides security protection for various electronic equipment, instruments and communication lines. When the electric circuit or communication line suddenly produces peak current or voltage due to external interference, the surge protection device can conduct shunt in a very short time, so as to avoid the damage of surge to other equipment in the circuit.


       Surge protection device is suitable for AC 50 / 60Hz, rated voltage of 220 V to 380V power supply system, to protect indirect lightning and direct lightning impact or other instantaneous overvoltage surge. It is suitable for the requirements of surge protection in home, tertiary industry and industrial fields.   

       Surge is also called surge, as the name implies, is the instantaneous overvoltage exceeding the normal working voltage. In essence, surge is a kind of intense pulse that occurs in only a few millionths of a second. The possible causes of surge include heavy equipment, short circuit, power switching or large engine. The products with surge blocking device can effectively absorb the huge sudden energy to protect the connected equipment from damage.

 

Basic characteristics
·The protection flow is large, the residual pressure is very low, and the response time is fast;
·Adopt the latest arc extinguishing technology to avoid fire completely;
·Adopt temperature control protection circuit, built-in thermal protection;
·With power status indication to indicate the working state of surge protective device (SPD);
·Rigorous structure, stable and reliable work.
