product description

SBW, DBW series single and three-phase fully automatic compensation power regulators are designed to stabilize the AC voltage by introducing and absorbing advanced technology from Western Europe and combining with my country's national conditions. When the external power supply network voltage fluctuates or the load changes When the voltage fluctuates, it can automatically keep the output voltage stable. Compared with other types of voltage stabilizers, this series of products has the advantages of large capacity, high efficiency, no waveform distortion, and stable voltage regulation. It is suitable for a wide range of loads, can withstand instantaneous overload, and can work continuously for a long time. There is no overvoltage, overcurrent, phase loss, phase sequence protection and automatic mechanical fault protection, as well as the advantages of small size, light weight, convenient use and installation, and reliable operation.

Use occasions

It can be widely used in large-scale electromechanical equipment, metal processing equipment, production lines, construction engineering equipment, elevators, medical equipment, embroidery textile equipment, air conditioners, radio and television and household Electrical appliances, lighting and other places that require voltage regulation.

SBW, DBW series voltage stabilizers should be used indoors, and can be specially customized for outdoor use. The normal use conditions are:

★Ambient temperature: -15℃～+40℃

★Altitude: <1000m

★Relative humidity: <90%

★No gas, vapor, chemical deposition, dust, dirt and other explosive and corrosive media that seriously affect the insulation of the voltage stabilizer.

★There is no serious vibration or bump in the installation site.
