Product Introduction

Contact voltage regulators feature no waveform distortion, small size, light weight, high efficiency, easy operation, reliable performance and long-term continuous operation. They are an ideal AC voltage regulating power supply.
This voltage regulator adopts an adjustable autotransformer structure. Coils are evenly wound on a toroidal iron core. Under spring pressure, the carbon brush is in close contact with the polished side of the coil. Rotating the shaft drives the brush holder, making the brush slide along the coil surface. By changing the contact position of the brush, the output voltage can be smoothly and steplessly adjusted within the adjustment range.

Scope of Application

This series of products is widely used in industrial production, scientific testing, household appliance testing and other fields for high-voltage equipment, inspection and test equipment, rectifier equipment, electrical product aging test equipment, aging lighting, to realize voltage regulation, temperature control, speed regulation, dimming and power control.
