AC automatic regulator

AC automatic voltage regulator is a power automatic voltage regulator that provides voltage stability function for AC voltage in the power supply environment. It is mainly used to convert voltage into stable voltage for the operation of electrical equipment in some unstable voltage environments.

AC automatic voltage regulator is a power supply equipment that can automatically adjust the output voltage. The function of AC automatic voltage regulator 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 at the rated working voltage as an auxiliary power equipment.

A.Working principle of communication automatic voltage regulator:

AC voltage automatic regulator adjusts the voltage within the specified input range to stabilize the output voltage within the specified range of electrical equipment.

There are many types of AC automatic voltage regulators, and the main circuit works in different ways, but basically (except for AC parameter automatic voltage regulators) they are input switches, sampling circuits, control circuits, and voltage regulation circuits.

1. Input switch: As an input switch for a voltage regulator, an air switch miniature circuit breaker with current limiting protection is generally used.

2. Voltage regulating device: It is a device that can regulate the output voltage. It can increase or decrease the output voltage, which is the most important component of an automatic voltage regulator.

3. Sampling circuit: detects the output voltage and current of the automatic voltage regulator, and transmits the changes in the output voltage to the control circuit.

4. Drive device: Due to the weak control circuit of the control circuit, a drive device is required for power amplification and conversion.

5. Drive protection device: a device that connects and disconnects the output of an automatic voltage regulator, usually using relays, contactors, or fuses.

6. Control circuit: Analyze the detection type of sampling circuit. When the output voltage is high, a control signal to reduce the voltage is sent to the driving device. When the output is output, the driving device will drive the voltage regulating device to reduce the output voltage. When the voltage is low, a boost control signal is sent to the driving device, and the driving device adjusts the output voltage through the driving voltage regulating device to stabilize the output voltage and achieve stable output.

When the output voltage or current exceeds the control range of the automatic voltage regulator. The control circuit will control the output protection device to turn off the output to protect the electrical equipment, while the output protection device is normally connected to the output, and the power receiving device can obtain a stable voltage supply.

B.The function of communication automatic voltage regulator:

The main function of an AC automatic voltage regulator is to provide stable voltage function for unstable AC voltage, which can convert unstable AC power into stable AC power for equipment use. In the event of insufficient power supply or voltage, AC automatic voltage regulators can provide the most reliable power guarantee. With the increasing demand in the market and the continuous improvement of automatic voltage regulator functions, automatic voltage regulator manufacturers have added electrical safety and equipment protection functions to automatic voltage regulators. The various functions of automatic voltage regulators can be customized according to the actual needs of users.

C.Application scope of communication automatic voltage regulator:

Communication automatic voltage regulator is mainly used to provide stable voltage output for AC voltage in the environment, and is widely used in monitoring equipment of industrial and mining enterprises, oil fields, railways, construction sites, schools, hospitals, postal and telecommunications, hotels, scientific research and other departments, precision machine tools, computed tomography (CT), precision instruments, testing devices, elevator lighting, imported equipment and production lines that require stable power supply voltage; It is also applicable to users at the end of low-voltage distribution networks with low or high power supply voltage and large fluctuation amplitude, as well as electrical equipment with large load changes, especially suitable for all voltage stabilizing electric fields with high requirements for grid waveform.
