Our Products

KDY-40N Neutral power supply lightning protection device

KDY-40N Neutral-line power surge protector is a neutral point-to-ground over-voltage protection device for power voltage transformers. It is designed and manufactured according to IEC and other relevant lightning protection standards, has no freewheeling, low residual voltage, and steep wave It has the advantages of rapid response, small discharge dispersion, and the ability to absorb various lightning and operating overvoltages.

KDY-I-25S Power supply lightning arrester

The flow capacity of the KEJIA KDY-I-25S power supply lightning arrester is large, and it is a switch type first class lightning protection protector. The lightning arrester has no leakage flow and no continuous flow. The performance is reliable and the work is stable. According to the principle of lightning protection, the power line still has high residual pressure after the lightning energy is released once, and the lightning energy should be released step by step through the rear lightning protection device of the lightning protection system so as to effectively protect the terminal electric equipment.

KDY-100F/760/3P power supply lightning protection device

KEJIA® KDY-100F power surge protector has a large flow capacity and is a Class 1 power surge protector. According to the principle of lightning protection, once the lightning energy is released by one time, there is still a high residual voltage on the power line. It should be matched with the lightning protection device at the rear stage of the lightning protection system so that lightning energy can be released step by step to effectively protect the terminal power supply. equipment.

KEJIA intelligent power distributor

The intelligent power divider is a very effective and practical monitor for remote power supply in the machine room. It also has the function of the extension line. So that managers can automatically grasp the power consumption from remote network, such as factory computer room, automatic control platform, server, router and other key equipment power supply.

New household lithium battery energy storage system

Household lithium battery energy storage systems absorb solar energy through solar panels and convert it into electrical energy. They can be turned on during periods of peak power usage and outages. This system relies on solar energy systems to reduce electricity bills and environmental protection.

KHB Series SPD Backup Protector

KHB series SPD backup protector has a variety of specifications according to the lightning protection level and the surge protector (power SPD, SPD). T1 products can withstand the impact of 10/350μs waveform lightning current, T2 grade products are suitable for With 8/20μs waveform power supply lightning protection device, customers can choose to use according to the requirements of lightning protection system design.
KHB series SPD backup protectors are designed with reasonable performance, and the volume conforms to the standard spacing of a protection module. It is very convenient to install and use.

KDY-I-25RX/440/4P power supply lightning protection device

KEJIA® KDY-I-25RX power supply lightning arrester is a combination of power supply lightning protection and lightning protection detection communication. When the failure of the power supply lightning protection module fails, the remote contact of the lightning protection module is dislocated. This contact connects to the NKP-LJ-04 SPD communication module. The failure of the collected lightning protection module can be recorded, and records can be recorded and managed in the background. The machine sends a signal. The NKP-LJ-04 SPD communication module can also record the number of times the lightning protection module is subjected to lightning surge discharge. The NKP-LJ-04 SPD communication module is controlled by a single-chip computer circuit, uses a high-brightness LED digital tube display, and has an RS485 communication interface. The parameters of the lightning protection module’s fault and discharge actions can be queried by the remote power integrated management system.

1SM65-63 small DC circuit breaker

1SM65-63 small DC circuit breaker for DC line control, overload and short circuit protection. And can be used for communications, telephone, locomotive, forklifts, forklifts, electric power, automation control, electrolytic control, security lighting and other industries. Products meet GB14048.2 standards.
