{{EN_1} Type II - 3 Three phase Voltage RegulatorDetailed product description：

TNSGC-II-3 three-phase voltage regulator

1. Voltage regulator (automatic voltage regulator) is mainly used for stabilizing the input voltage of various equipment, and can be widely used in factories, rural areas, scientific research, production lines, construction equipment, precision instruments, machine tools, medical equipment, hotels, sports venues, cinemas, elevators, broadcasting stations, computer rooms and all places that require AC stable power supply.
2. The voltage regulator (automatic voltage regulator) has high voltage stabilization accuracy, no waveform distortion, no phase shift, short response time, high efficiency, high power factor, and can operate continuously; Can adapt to resistive, capacitive, and inductive loads.

3. Three phase automatic voltage regulators are specially designed and produced to adapt to places with unbalanced power grids or unbalanced loads.

4. The difference between sub survey and unified survey:

1) A distributed AC voltage regulator consists of three control circuits, three sets of motor transmission mechanisms, and three sets of voltage regulators (with compensating transformers); Each phase is an independent mechanism, and the feedback signal is taken from the output voltage of this phase. The circuit and magnetic circuit are integrated and do not interfere with the other two; The accuracy is adjustable from 1% to 5%, with a maximum adjustment of 1%. It does not require high balance between the power grid and the load.

2) A unified AC voltage regulator consists of a control circuit, a set of motor transmission mechanisms, and a set of voltage regulators (with compensating transformers); The feedback signal is taken from the three-phase output voltage, and the circuit and magnetic circuit are integrated into three phases. The accuracy is adjustable from 1% to 5%, and is generally reduced to 3%. It has high requirements for the balance of the power grid and load.
