Three phase voltage regulators are usually used in large industrial equipment with an input voltage of 380V. This type of voltage regulator can stabilize the AC voltage and effectively solve the shortage of voltage regulation intermittent oscillation compensation and voltage regulation interference.
220V single-phase voltage regulator and 380V three-phase voltage regulator, the common voltage is divided into 220V single-phase voltage and 380V three-phase voltage, and the most commonly used voltage in the industry is 380V, that is, three-phase voltage, can also be said It is 380V three-phase voltage, and when such voltage is unstable, we need a 380V three-phase voltage regulator.
For the 380V three-phase voltage regulator, the most common wiring method is a three-phase four-wire voltage regulator, which is composed of three live wires and one neutral wire.
The less-used 380V three-phase voltage regulator is a three-phase three-wire system. This type of voltage regulator only needs to be connected to three live wires. No neutral line is required. For the 380V three-phase voltage regulator, the wiring system is completely based on the user's environment and the wiring requirements of the load equipment.
According to the working mode, the voltage regulator can be divided into three mainstream regulators: non-contact regulator (electronic regulator), purifying AC stabilized power supply, and carbon brush regulator (with contact regulator). The power of the regulator determines the size of the load. If the load power is greater than the output power of the regulator, it will not only cause damage to the regulator but for some low-quality (without load protection) regulators, the damage will not only affect the quality of the product produced by the load but also Will cause damage to the device.
The voltage regulator is composed of a voltage regulator circuit, a control circuit, and a servo motor, when the input voltage or load changes, control The circuit performs sampling, comparison, and amplification, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage regulator. The coil turns ratio is automatically adjusted to maintain the stability of the output voltage. The larger-capacity regulator also uses the principle of voltage compensation.
The difference between the single-phase voltage regulator and the three-phase voltage regulator is the input and output voltage and the number of access lines. The internal structure and amount are also different. In use, the single-phase voltage regulator is only for power supply of single-phase electrical appliances, while the three-phase voltage regulator can provide regulated power supply for the three-phase voltage regulator, and can also make special requirements for the factory at the time of production. powered by.
The three-phase fully-compensated power stabilizer is the advanced technology imported from Shuo Gong Electric to absorb Western Europe and is designed to stabilize the AC voltage. When the voltage fluctuation of the external power supply network or the load change causes the voltage fluctuation, it can automatically maintain the stability of the output voltage.
Three-phase voltage regulators are usually used in large industrial equipment with an input voltage of 380V. The household voltage is 220V, which is a combination of live lines and neutral lines. Therefore, the general household voltage regulator is to choose a single-phase regulator rather than a three-phase regulator. Therefore, three-phase electricity generally refers to industrial electricity. The input and output wiring of the three-phase voltage stabilizer is generally connected by three live wires. Wiring methods include three-phase three-wire, three-phase four-wire, three-phase five-wire, etc.
The characteristics of the three-phase voltage regulator are good efficiency and excellent characteristics: the use of high magnetic flux, low iron loss silicon steel sheet makes a no-load loss, no load current is minimized, and the highest efficiency in full load use makes the regulator play a high efficiency Yes, reduce power loss.
Wide AC power input range: In the tolerable input range, when the poor AC input power supply can still work normally, all components have been specially selected to resist instantaneous high voltage and large current.

With this product, it can achieve smaller volume, lighter weight, and maximum capacity.

Modular design is adopted in the interior, all components are standardized, and the main structure coil part, as long as the interior is kept clean, no maintenance or maintenance is required.
Single-phase voltage regulator generally refers to 220V input and output. The general input and output lines are the neutral lines and the live line, and then the ground wire is added. The three lines are used as the input and output phase numbers. Single-phase voltage regulators are generally used for appliances with lower power. Such as household appliances, office appliances, small experimental equipment, etc.
