SJWF high power automatic voltage stabilizer

No.One second voltage stabilization, stable output, pure copper coil
SJWF high-power automatic voltage stabilizer is designed by our company to stabilize AC voltage by absorbing advanced technology from Western Europe and combining it with my country's national conditions. It can automatically maintain the stability of the output voltage when the voltage of the external power supply network fluctuates or the voltage fluctuates due to load changes.

Description
■ Features

Compared with other types of voltage stabilizers, this series of products have the advantages of large capacity, high efficiency, no waveform distortion, stable voltage regulation, etc. They are suitable for a wide range of loads, can withstand instantaneous overloads, can work continuously for a long time, automatically stabilize voltage, and are equipped with overvoltage protection, phase loss, phase sequence protection and automatic mechanical failure protection. This machine has the advantages of small size, light weight, easy use and installation, and reliable operation.

■ Scope of Use

This series of voltage stabilizers have been widely used in power supply voltage stabilization of electronic computers, precision machine tools, precision instruments, experimental devices, elevators and production lines in industrial and mining enterprises, printing, machine tools, post and telecommunications, railways, construction sites, schools, hospitals, hotels, national defense, scientific research and other departments. It is also suitable for low-voltage power distribution terminal users with low power supply voltage and large fluctuations, and electrical equipment with large load fluctuations, such as elevators, cranes, mixers and other places that require voltage stability.

■ Precautions for Use

This series of voltage stabilizers should be used indoors, and the normal use conditions are:
1,Ambient temperature:-15℃~+45℃
2,Altitude not exceeding 1000m.
3,Relative humidity:≤90%
4,The installation site should be free of gases, steam, chemical deposits, dust, dirt and other explosive and corrosive media that may seriously affect the insulation of the voltage stabilizer; the installation site should be free of severe vibration or bumps. Any special use conditions that do not meet the above requirements should be determined by the user and our factory through consultation.

■ Remark
When ordering, please specify: model, capacity, voltage regulation accuracy, input voltage range, output voltage; phase voltage 220V±30%, line voltage 380V±30% (need to be specified when ordering). Special requirements can be designed and produced according to user requirements;
