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.
