Like all outdoor buildings, photovoltaic devices are vulnerable to lightning strikes. By far the biggest culprit for the power surges that damage solar panels are direct and indirect lightning strikes on the system. As one of safety automation system devices, our solar SPD DC power surge protectors help prevent DC overvolt voltage damage caused by lightning surges and other strong changes in power.

Features & Advantages of Screw Mounting SPD Connection Intrinsic signalsafety certification; explosion proof electrical product certification.

GS5000-EX Analogue Intrinsic Safety Loop Barrier Power These products can work as AI isolated barriers to provide separate power to the transmitter located in the hazardous area and transfer the current from hazardous area to safe area. They can also work as AO isolated barriers to transfer current signal from the safe area to the hazardous area and drive devices like actuator in field.

Varistors, also known as voltage-dependent resistors, are used as part of surge protective devices (SPDs). Varistors are designed to provide protection against transient overvoltages by limiting the voltage across the device to a safe level. Varistors are usually composed of sintered material consisting of zinc oxide grains embedded in a ceramic matrix. When an overvoltage occurs, the varistor exhibits a low resistance, allowing a large current to flow, thereby reducing the voltage across the device. Varistors are available in both AC and DC versions, with a variety of ratings to suit different applications.
