How to choose 3 phase voltage stabilizer - 3 phase voltage stabilizer

NO1 power

 

The power of the voltage stabilizer can be purchased according to the sum of the equipment power equipment.

 

 

NO2 pay attention to the voltage

 

 

It is clear whether it is three-phase 380V or single-phase 220V

 

 

NO3 regulated power supply price

 

 

Price has always been a concern of customers. Factors such as different brands and different powers affect the price. You can choose a certain price range according to the comparison.

 

 

NO4 regulated power supply quality

 

 

Brand effect, choose a power supply manufacturer with high credibility, logistics and after-sales service are more secure and reliable.

 

 

NO5 shop around

 

 

When choosing a 3 phase voltage stabilizer, you can shop around, and then decide what to buy. After all, for electrical equipment used in the power grid, we seek quality and assurance.

 

 

What is a voltage stabilizer

 

 

A voltage regulator is a device that stabilizes the output voltage. The voltage stabilizer is composed of a voltage regulation circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit performs sampling, comparison and amplification, and then drives the servo motor to rotate, so that the position of the carbon brush of the voltage regulator changes, and the coil turns ratio is automatically adjusted to maintain the stability of the output voltage.

 

 

The role of the voltage stabilizer

 

 

A voltage stabilizer is a power supply circuit or power supply equipment that can automatically adjust the output voltage. Its function is to stabilize the power supply voltage that fluctuates greatly and does not meet the requirements of electrical equipment within its set value range, so that various circuits or electrical equipment can be stabilized. The equipment can work normally under the rated working voltage.

 

 

The original power regulators relied on the beating of relays to stabilize the voltage. When the grid voltage fluctuates, the automatic correction circuit of the power regulator is activated to make the internal relay operate. Forcing the output voltage to remain near the set value, the advantage of this circuit is that the circuit is simple, but the disadvantage is that the voltage regulation accuracy is not high, and every time the relay jumps and shifts, it will cause an instantaneous interruption of the power supply and spark interference. This greatly interferes with the reading and writing work of computer equipment, and it is easy to cause error signals in the computer, and in severe cases, the hard disk will be damaged. Most of the high-quality small voltage stabilizers use the method of motor-driven carbon brush to stabilize the voltage. This voltage stabilizer has little interference to electrical equipment and has relatively high voltage stabilization accuracy.

 

 

The working principle of the voltage stabilizer

 

 

The voltage regulator consists of a voltage regulator circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit performs sampling, comparison, and amplification, and then drives the servo motor to rotate, so that the position of the voltage regulator carbon brush changes. By automatically adjusting the coil turns ratio, the output voltage is kept stable. The voltage stabilizer with larger capacity also works on the principle of voltage compensation.
