TONGOU provides high-quality DC surge protective device (DC SPD). SPD is also known as a lightning protection device. SPD is an electronic device that provides security protection for various electronic equipment, instruments and communication lines. When the peak current or voltage is suddenly generated in the electrical circuit or communication line due to external interference, SPD can conduct the shunt in a very short time, so as to avoid the damage of surge to other equipment in the circuit.
DC SPD 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 another instantaneous overvoltage surge, applicable to the requirements of surge protection in-home, tertiary industry and industrial fields.
TONGOU always adheres to the principle of “quality first”, adheres to management informatization, production automation continuously improves production process quality and production management level.
