 Industrial Electrical Wiring Accessories , Contact AC DC Voltage Regulator 3 Phase 380V

 


 
General
 
 
 
This type of voltage regulator is in the structure of adjustable self-coupling transformer. it winds coil on ring shaped core, the brush fits close to the polished surface of coil under the press effect of sping, rotating shaft drives the brush holder and make brush slide along with the coil surface. so that to change the contact position of brush, i.e.change the winding ratio of primary and secondary coils, this enables the output voltage to get smooth steepless control. The products are featured with undistorted waveform. compact volume,light weight,high efficiency. convenient operation, reliable, long-term operation, etc.
 
 
 
Applications:
 
 
 
The products are widely applied to industries(such as chemical, metallurgy, instruments, meters, electromechanical manufacturing, light industry,etc), scientific experiments, public service household electrical appliances, used to realize voltage regulation, temperature control, speed adjustment, light modulation, power control, etc, it is really a ideal AC voltage regulating power supply.
