Three-phase high precision full automatic 15kVA AC voltage stabilizer is composed of regulator, servo motor, automatic control circuit. When the voltage of the power grid is not stable or the load varies, the automatic sampling control circuit makes a signal to drive the servo motor to adjust the position of the carbon brush of the regulator as to make the output voltage stable.

Tips: How to select a right voltage stabilizer?
It depends on the type of electrical equipment you use. Generally, the load is not purely resistive. Therefore, in the actual selection, the regulated power supply shall be reasonably selected according to the rated power, power factor and load type of the electrical equipment. And the output power shall be reserved with appropriate margin, especially for the impact load selection, the margin shall be larger, and the specific selection is as follows:
- For pure resistive load such as incandescent lamp, resistance wire, electric furnace and other equipment, the power of the voltage regulator shall be 1.5-2 times of the power of the load equipment.
- Inductive and capacitive loads such as fluorescent lamps, fans, motors, water pumps, air conditioners, computers, refrigerators, etc. The power of the regulator shall be 3 times the power of the load equipment.
- Under the condition of large inductive and capacitive load, the starting current of the load should be considered to be very large (up to 5-8 times of the rated current), so the power of the voltage regulator should be more than 3 times of the load power.
