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.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
