Surge protector, also called lightning protector, is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When a spike current or voltage is suddenly generated in the electrical circuit or communication circuit due to external interference, the surge protector can conduct and shunt in a very short time, so as to prevent the surge from damaging other equipment in the circuit. The protection of indirect lightning and direct lightning effects or other transient overvoltage surges is suitable for the requirements of surge protection in households, tertiary industries and industrial fields.
The DCSPD40 series surge protection device is used in the photovoltaic power supply network to protect and resist the impact of lightning and high energy on the equipment. This product must be installed in a parallel DC network.
