Overview

Three-phase high precision full automatic 15 kVA AC voltage stabilizer is composed of the regulator, servo motor, and 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 to make the output voltage stable.

Tips: How to select the 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. The output power shall be reserved with an appropriate margin, especially for the impact load selection, the margin shall be larger, and the specific selection is as follows:

For pure resistive loads such as incandescent lamps, resistance wire, electric furnaces, 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.

15kVA 3 phase AC automatic voltage stabilizer

I was specifically looking at the ATO-AVS-3P15K voltage stabilizer unit. Do you have any experience with custom solutions? Would it be possible to produce this version without housing, wheels etc, to make it easier to mount inside a machine?

Yes, we can.

Do you have a solution for whole house voltage stabilizer?

I live in Michigan and in my area we experience a few brownout per yer and it is the 2nd time it has burned out several recessed LED fixtures that I have to replace. Do you have a solution for whole house voltage stabilizer? My home is 2500sq ft., I have a 200 amp circuit panel and I also have a 10k whole house generator.
