DS50PV/51 surge protectors are type 2 surge protectors designed to protect against lightning surge voltages in photovoltaic power supply networks. These surge protectors use specific varistors as the primary protective element to provide protection in both common mode and differential mode.
Varistors are devices that have a nonlinear resistance that decreases as the applied voltage increases. This characteristic makes them ideal for use in surge protectors, as they can effectively shunt high voltage surges to ground and protect sensitive equipment. In the case of DS50PV/51 surge protectors, the varistors are used to provide protection in both common mode and differential mode, which helps to ensure maximum protection for PV systems against transient overvoltages.
The DS50PV/51 surge protectors also feature a compact and robust design, making them well-suited for use in harsh outdoor environments. They have a high discharge capacity and are designed to be installed in series with the DC power supply, providing comprehensive protection for PV systems against transient overvoltages.
Overall, DS50PV/51 surge protectors are an effective and reliable solution for protecting photovoltaic power supply networks against lightning surge voltages. Their use of specific varistors and protection in both common mode and differential mode ensures maximum protection and reliability for PV systems.
