Ask for help What is the working principle of an air conditioner voltage regulator

How does a voltage regulator work? A voltage regulator is a device that stabilizes the output voltage. The voltage regulator is composed of voltage and constant voltage, control circuit, and servo motor.

When the input voltage or load changes, the control circuit sampling, compares, amplifies, 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, so as to keep the output voltage stable. Scope of application: Voltage regulators can be widely used in:

Electronic computers, precision machine tools, computed tomography (CT), precision instruments, test devices, elevator lighting, imported equipment and production lines of industrial and mining enterprises, oil fields, railways, construction sites, schools, hospitals, posts and telecommunications, hotels, scientific research and other departments require stable voltage of power supply. It is also suitable for users at the end of the low-voltage distribution network with low or high power supply voltage and large fluctuations and large load changes, especially for all regulated power places with high requirements for power grid waveform. The high-power compensating power regulator can be connected to firepower, hydropower, and small generators.

Function introduction: The voltage regulator is a power supply circuit or power supply equipment that can automatically adjust the output voltage, and 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 work normally under the rated working voltage. The original power regulator stabilized the voltage by the runout of the relay.

When the grid voltage fluctuates, the automatic correction circuit of the power regulator is activated, so that the internal relay acts. Forcing the output voltage to be kept near the set value, this circuit has the advantage of simple circuit, 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 interferes greatly with the reading and writing work of computer equipment, which is easy to cause error signals in the computer, and in serious cases, it will also damage the hard disk.

High-quality small voltage regulators, most of which use the motor to drag the carbon brush to stabilize the voltage, this kind of voltage regulator has little interference to electrical equipment, and the voltage stabilization accuracy is relatively high.

If it can be determined that the supply voltage is persistently too low for the air conditioner to function properly, it is advisable to consider installing a transformer instead of a regulator, as the cost of installing a regulator is too high. From the current situation, the cost of installing a voltage regulator is more than 300% higher than the cost of installing a normal transformer. If the air conditioning power supply voltage continues to be low, and it is more stable and stable at a lower power supply voltage value, you can consider installing an ordinary transformer.

The power supply voltage of the air conditioner is generally within 10% of the rated voltage, and the air conditioner will not and should not have problems, and more than 15% may have problems. Before choosing whether to determine the transformer or the regulated power supply, it is recommended to consult an air conditioning professional to diagnose and determine.

Useful.

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

Voltage Regulator Product Classification: Auto-coupled--- uncompensated regulated power supply (single-phase, three-phase 9KVA and below) has a small capacity and a voltage output of 110V. Compensated --- compensated regulated power supply (single-phase 5kVA vertical type and above, three-phase 15kVA and above) has a compensation transformer and no 110V output.

The function of the voltage regulator is to stabilize the voltage, when the voltage is high, it will come down, and when the voltage is low, it will rise again. When buying a voltage regulator, it is recommended that you choose a voltage regulator that is three times more powerful than the actual power, because the voltage regulator has to overcome the surge shock of the mains power and the starting shock of inductive loads (such as refrigerators, air conditioners, motors, and electric motors}) in actual work

When purchasing a voltage regulator, when choosing a contact type automatic voltage regulator, the rated output voltage regulator should have a larger margin than the adapter type automatic voltage regulator. Check the appearance quality and processing technology.

Buttons, switches and other operations should be flexible and reliable, parts should not be loose and shake the parts, there should be no rolling sound in the machine, otherwise there are foreign objects in the machine.

The voltage regulator can automatically stabilize the voltage, and the mains direct output and the voltage stabilization output have two sets of systems, with overvoltage protection and delay protection functions, which are safe and reliable, and adapt to any nature of load. If the voltage is low, you need to use a voltage regulator, otherwise the appliance can be easily damaged. The voltage regulator sold directly by China Airlines is of good quality and not expensive.

I bought it last year and have used it until now without any problems. Shop.

The input power is about 1850W for the air conditioner, considering the instantaneous starting current when the air conditioner starts, it is recommended that you buy an AC voltage regulator above 6000W, ** about 450 yuan.

Yuefeng brand, motor servo, multiply your air conditioner power by 3 is the wattage of the voltage regulator you want to buy!

That's how I bought it and it works!
