  • Product Description
  • Product parameters
  • DBW series single-phase automatic compensation power regulator is suitable for the power supply network voltage fluctuations or load changes caused by voltage passivity, can automatically maintain the output voltage stability. Compared with other types of voltage regulators, this series of products has the advantages of large capacity, high efficiency, no waveform dark change, voltage regulation balance and so on. Applicable to a wide range of loads, can withstand instantaneous overload, long-term continuous work. Manual/automatic switch, easy to use and install, reliable Operation Point.

    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.
