Surge protective device, suitable for 50 / 60Hz AC, rated voltage of 220 V to 380 V power supply system, for indirect lightning and direct lightning impact or other transient overvoltage surge protection, suitable for family residential, tertiary industry and industrial field surge protection requirements.

Intelligent Surge

There is no uniform definition of intelligent SPD at home and abroad, but the concept of intelligent SPD has been recognized by R&D designers and users in practice. Intelligent SPD should have the following four basic characteristics:
① Surge protection function and safety performance;
② Monitoring function of operating parameters;
③ Fault alarm and failure prediction function;
④ Communication and networking functions.

Intelligent SPD realizes lightning current monitoring, which can monitor parameters such as lightning peak current and lightning times of tower in real time.

With the organic combination of intelligent surge protector and NB-IoT wireless module, many problems in substation intelligent lightning monitoring will be solved easily.

With the development of smart cities, the wide application of new technologies such as Internet of Things, cloud computing and the next generation Internet, intelligent SPD based on NB-IoT technology is increasingly becoming an important weapon for the communication industry to ensure the security of network operation. Monitoring, controlling and managing the lightning protection system of communication stations will be the only way to improve the management level of communication networks. The application research of NB-IoT will strongly promote the industry innovation of intelligent surge protector and promote the progress of new technology.This product is an intelligent surge protector (SPD 80kA), which mainly collects SPD damage status, air switch trip status, SPD false grounding and poor grounding status and SPD action times; it is equipped with standard RS485 interface data communication and supports wired and wireless communication methods ; It can be used in networking or independently, and can provide custom programming interface for customers to connect with other private protocols.

Product installation

The main purpose of this product is to monitor the status and service life of a surge protector (SPD). It is generally installed and used indoors, and is usually installed next to the surge protector.

●Installation method: 35mmDIN standard rail installation, in line with DINEN60715 standard.
●Choose a suitable position to fix the DIN rail in the distribution box, and clamp the monitoring module onto the rail to fix it.
●Monitoring module wiring ports ⑦ and ⑧ are connected to the 485 communication module interface; ⑨ and ⑩ are auxiliary dry contact modes, regardless of polarity, one end is connected to the common end, and the other end is connected to the normally closed end.
●Connect the power line and communication line according to the color, and don’t connect it wrongly.
● The specifications of the power inlet and outlet wires and the ground wire should meet the specifications, and the wires should be short and thick, and the grounding resistance should be less than 4 ohms.
