DC lightning surge protection pv surge arrester 500v dc surge protection device

Special purpose photovoltaic DC surge protector, overvoltage, current limiting and lightning protection circuit breaker.

Product introduction

Photovoltaic DC surge protector is a lightning protection product designed for the solar photovoltaic system based on the relevant standards. The lightning arrester adopts the multi-stage protection circuit, selects the brand components and makes use of the advanced production technology. It has the characteristics of large flow capacity, low residual pressure level, sensitive reaction, stable performance, reliable work and so on. It is suitable for the requirements of DC surge protection in photovoltaic power generation, wind power generation and other industrial fields.

Working principle of product

In the solar photovoltaic system, the inductive or capacitive coupling voltage is caused by the lightning shock and the switching operation of the upstream power supply system. Therefore, the surge may damage the photovoltaic modules and inverters, which will cause serious consequences for the operation of the photovoltaic system. The photovoltaic lightning arrester is specially developed for this purpose. The lightning protection module of the DC power supply, once the high voltage, and endanger the insulation of the protected equipment, the lightning arrester acts immediately, and the high voltage impact current is directed to the earth, thus limiting the amplitude of the voltage and protecting the insulation of the equipment. When the overvoltage is gone, the arrester is restored to its original state quickly, so as to protect the power equipment.

Product features

1. it can access multi-channel solar array at the same time. The maximum current per channel can reach 11A, which can meet different user needs.

2. can be configured according to the needs of the sensor and monitoring and display module to measure and monitor the current of each road, and can record and display the operating conditions remotely, without the need for on-site selection;

3. high quality flame retardant materials, fire insulation, rust prevention and safety.

4. create the wiring connection to prevent incorrect contacts, and add a guarantee to your safety.

Product specification

Use of attention

1. standard RJ45 interface can be conveniently connected to the front end of the protected equipment. The grounding path should be as short as possible, and the length should not exceed 1.5 meters.

2. To avoid unnecessary induction loops, we should mark the PE conductor of each device.

3. identify the input / output interface identifier of the lightning protector, input the external line and output the connection device.

4. after correct installation, it can work steadily for a long time. If it is found that the transmission performance of the system is reduced or the signal is interrupted due to the cause of surge protection, it should be maintained or replaced in time.
