Voltage Regulator Contact Details

The TND single-phase and TNS three-phase fully automatic AC voltage stabilizer is composed of a contact regulator, sampling circuit and servo motor. It achieves high-precision voltage stabilization by automatically adjusting the position of the carbon brushes.

This series of products have a small size, light weight, low waveform distortion at the output, reliable performance, and can operate continuously for a long time. They are also equipped with an overvoltage protection function to ensure the safety of the load.

TNS Series Stabilizer System

The TNS three-phase series is composed of single-phase units and can achieve phase-by-phase regulation. It can also be equipped with under-voltage and delay protection options.

The product is widely used in various scenarios such as industrial production, commercial and household electricity, and is an ideal stable voltage power supply with reliable performance and economic practicality.

Servo Motor Control
Through the precise adjustment of the servo motor, the output voltage can be stabilized within the allowable error range of the rated value, meeting the voltage quality requirements of precision equipment.
Transformer Tap Regulation
Unlike electronic chopping type voltage regulators, this product achieves voltage regulation by changing the tap position of the transformer. The output waveform has extremely low distortion and almost no harmonic interference.
Real-time Sampling
The control circuit conducts real-time sampling. When the voltage fluctuates, it promptly issues instructions to drive the motor for adjustment. The response is fast, and the process is smooth.

Scope of application
Stabilizer Application Grid

During peak periods or in remote industrial areas, the voltage tends to fluctuate like a roller coaster. We designed an ultra-wide voltage regulation range, even if the input voltage is as low as 140V or as high as 270V, still stable output of pure 220V power. There is no need to worry about the difficulty of starting at low voltage or burning the equipment at high voltage.
