Recently, it is a season of high thunderstorm and lightning. The unstable weather in the past day has brought many troubles to people's travel and also brought some safety risks to electricity. The products of SPD of Jiangsu Sfere Electric can effectively prevent and reduce the harm of lightning overvoltage to low voltage power supply equipment.
Surge protector, also known as lightning protector, is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines.
When the electrical circuit or communication line suddenly generates peak current or voltage due to external interference, the surge protector can conduct shunt in a very short time, so as to avoid the damage of surge to other equipment in the circuit.
Applicable to AC 50/60HZ, rated voltage 220V/380V power supply system, to protect the surge affected by indirect lightning and direct lightning or other instantaneous overvoltage. Suitable for the requirements of surge protection in industrial field, tertiary industry and residential buildings.
