  • Product Description
  • Product parameters
  • SBW series automatic power supply can prevent voltage sags and power cuts. It is well suited to regions with unstable power grids, such as Africa, Asia and parts of Europe. The SBW regulator can keep the output voltage stable automatically when the grid voltage fluctuates or the load current changes. The input voltage range can be customized to ± 10% , ± 15% , ± 20% , ± 25% , ± 30% , ± 50% , and the output voltage precision can be set to ± 2% ~ 5% . SBW series voltage regulators are easy to install and operate, and can provide you with reliable and stable power supply in the power environment where the quality of the main power supply can not be guaranteed.


    Product details:

    Pole type voltage regulator is made of heat-resistant h-class enameled wire; coil is made of heat-resistant 180 ° C insulating paint with epoxy coating on the surface; coil and carbon brush sliding parts are polished, the iron core surface increases antirust treatment, good insulation, high temperature resistance, strong moisture resistance, low noise, low coil loss, can effectively improve the service life.

    The compensating transformer is made of temperature-resistant h-class enameled wire, the transformer is made of temperature-resistant 180 ° C insulating varnish, the coil is designed without framework, and there are ventilation slots between the coils, and the iron core is made of new high-quality cold-rolled silicon steel sheet, it has good insulation, high temperature resistance, strong moisture resistance, low noise, low temperature rise, high efficiency and long service life by adding epoxy coating on the surface.

    High quality intelligent control circuit board for voltage regulator control system, step-up/step-down uses 30A relay control (30A relay drives motor current about 1A, start current about 5-7A, enough margin, can work frequently) ;

    7 inch LED display, can display input voltage, output voltage, current, frequency, fault, parameters can be set. There are over-voltage, under-voltage, over-current, lack of phase, fault, and other situations can be automatically uninterrupted switching power function. Electrical accessories contactors are using CHINT brand, can also be based on customer demand to use other brands, such as Schneider, Abb.

    Products used laser cutting machines, precision machine tools, printing machines, and other industrial machinery; elevators, shopping malls, office buildings, hospitals, construction sites, automated production lines and all need voltage stability.
