DC surge protector FK-PV1000 is applicable to solar system. It is a voltage limiting surge protector. It is used to prevent the damage of photovoltaic power generation DC power supply system caused by electric overvoltage and transient overvoltage. It is a special solar surge protector to protect the overvoltage of DC power supply system. It has positive and negative common-mode protection to ground and positive and negative differential-mode protection to ensure the most suitable lightning protection for DC module inverter. It can also be equipped with remote signaling alarm function as required (remote signaling status: normal: 1,3 NC, fault 1,3 NO). The salient point of the DC surge protector is that the output residual voltage is low and the response time is fast. Especially when the lightning surge passes through the protector, the subsequent current will not appear. In case of overheating, overcurrent and breakdown failure due to electric shock, the built-in failure tripping device can automatically separate it from the power grid.
