Solar Surge Protection Device Slocable

What is the principle of a solar surge protection device and how to choose an appropriate solar surge protector?

        Solar surge protection device is a kind of electronic device that provides safety protection for various electronic equipment and communication lines. When a peak current or voltage is suddenly generated in the electrical circuit or communication circuit due to external interference, the pv surge protection can conduct and shunt in a very short time, so as to avoid the damage of the surge to other equipment in the circuit. This article focuses on what is the principle of a solar surge protector and how to choose an appropriate surge protector.

What is the principle of a solar surge protection device?

        Solar surge protection devices are also called lightning protection devices. According to the national IEC standards, they are mainly used to limit the overvoltage and overcurrent flowing into the line. The solar surge protector has an efficient protective effect on electronic equipment, it bears the expected lightning current. After the maximum suppression of the pv surge protector, it effectively absorbs the power frequency continuous current generated after the lightning current passes, and it will pass through the power line and signal transmission line. The instantaneous overvoltage or overcurrent is suppressed within the voltage that the equipment and protector can withstand, or a huge lightning current is introduced into the ground to protect the equipment.

        The standard solar surge protection device delivers the current from the power socket to multiple electrical and electronic devices plugged into the power board. If a surge or spike causes the voltage to exceed an acceptable level, the solar SPD will transfer the excess current to the ground of the power outlet.

        In the most common solar surge protection devices, there is a component called a metal oxide varistor, which is used to transfer excess voltage. MOV is composed of three parts: In the middle is a metal oxide material, and two semiconductors are connected to the power supply and ground.

        These semiconductors have variable resistances that change with changes in voltage. When the voltage is lower than a certain value, the movement of electrons in the semiconductor will produce extremely high resistance. On the contrary, when the voltage exceeds this specific value, the movement of electrons will change and the resistance of the semiconductor will be greatly reduced.

How to choose the appropriate solar surge protection device?

        When buying a solar surge protection device, you usually need to be very careful. The main reason is that the current market is flooded with products that hardly have any effect. The best way to buy a suitable product is mainly to research a specific model. Of course, you should carefully pay attention to several quality marks, and at the same time you should better understand the performance level of the product.

        When making a selection, you should check the corresponding price. Under normal circumstances, do not have too much expectations for relatively low-priced DC SPD. The main reason is that these devices usually use simple and inexpensive MOVs, so their capacity is quite limited. In the course of daily use, once a large surge or spike occurs, the user’s system will not be able to protect the user’s system.

        Of course, a high-priced dc surge protector solar does not mean good quality. For consumers who want to choose the most appropriate protector, they should check the corresponding signs. This is relatively important.

        This article focuses on the principle of the solar surge protection device and how to choose the appropriate solar surge protector. Through these materials, everyone should be able to understand the principle of the solar DC SPD. The role of surge protectors is obvious, but everyone should pay attention to choose to buy with good quality.
