The rated capacity of TNS(SVC) series three phase automatic voltage regulator stabilizer ranges from 6KVA to 120KVA for normal products. The normal voltage regulation range is 380V±20% (It could be customized according to customers' requirements).
TNS voltage stabilizers regulate three phase voltage independently to ensure the stability of each phase voltage. The input wiring terminals are three phase and a neutral line while the output wiring terminals are three phase with neutral line shared with the input one. As for the displaying meters, this product features in LCD display screen, which could show input voltage, output voltage, load current, and other parameters etc.

TNS voltage regulator features in fast response speed, high efficiency, high output accuracy, no additional waveform distortion, sound voltage regulation performance, suitability for various loads, strong instantaneous over-load bearing capability, suitability for constant work. It is designed with various protection functions, including over-voltage, under-voltage, over-current, phase lack, phase failure, and mechanic fault etc.
This three phase automatic voltage regulator has LCD display screen system to indicate input voltage, output voltage, output current, and other technical parameters etc.
It is much conveneint for the end users to monitor the working status of the AVR.
Note: if the rated output voltage is 220V/230V/400V/415V/440V/480V, the figure would be displayed accordingly (the picture above is 380V output voltage one).
The wiring position of this automatic voltage regulator: the wiring terminals are of quality material and the wiring marks are very clear. It's much easy for customers to connect wires correctly.
For standard design, there are input A B C and neutral line (the neutral line must be connected), and output a b c and neutral and grounding (while the neutral line is shared for input and output). If there is no neutral line at spot, it could be customized as with no neutral line terminal.
This part shows the copper coil for voltage regulation of the voltage stabilizer/regulator. Copper material facilitates low electricity resistance, high efficiency, and good electricity conductivity, which would improve the performance of the avr.
Servo motor display: servo motor plays a significant role in the process of voltage stabilization. It would drive the carbon brush to rotate along the surface of the coil when it receives the signal of voltage fluctuation.
This part shows the carbon brush of the AVR. It is an important part for the AVR. This carbon brush is made of 1017 material, facilitating the properties of less abrasion and smooth performance.
Circuit board: it features in high precision, fast signal transmission speed, and auto sampling.
It is very important for the AVR to react fastly and precisely.
For sound heat emmision, the cabinet/enclosure of the automatic voltage stabilizer is designed with multiple heat emission holes. Also, there would be a heat draught fan to lower the temperature inside the cabinet.
For convenient movement of the voltage regulator, we equip this product with four universal wheels, which have the proerties of no noise and wear-resistance.
