Voltage stabilizer

The power supply voltage regulator is a power supply circuit or power supply equipment that can automatically adjust the output voltage. The equipment can work normally under the rated working voltage. The voltage stabilizer can be widely used in: electronic computers, precision machine tools, computed tomography (CT), precision instruments, test devices, Elevator lighting, imported equipment and production lines and other places that require stable voltage of the power supply. It is also suitable for users at the end of the low-voltage distribution network where the power supply voltage is too low or too high, and the fluctuation range is large, and the electrical equipment with large load changes, especially suitable for all voltage-stabilized power sites that require high grid waveforms. The high-power compensation type power stabilizer can be connected to thermal power, hydraulic power and small generators.

Working principle:

The power regulator is composed 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 to keep the output voltage stable. The AC voltage stabilizer with larger capacity also works on the principle of voltage compensation.

Feature:

1. Wide input voltage range, adapt to a wide range of car battery voltage changes.

2. The high-efficiency super capacitor is combined with the switching power supply system to work smoothly and intelligently, and effectively protect the car battery.

3. Stable voltage output, eliminating the influence of voltage fluctuations caused by the internal resistance of batteries and wires in large dynamic operation, so that the audio-visual system can work stably at the high end of the rated voltage range, and maximize the power output and dynamic range of the power amplifier.

4. Low ripple output, effectively suppressing power supply noise interference.

5. Low impedance, strong instantaneous dynamic response capability, making the bass powerful, the midrange mellow, and the treble transparent. power requirements.

6. High power (when 12V is input, the power is 360W), which meets all the original car audio and video systems within six channels

7. High efficiency (switching frequency 200Khz), low power consumption, no noise, low heat generation, no fan, no need for ACC control, small size, light weight, easy installation and maintenance-free use.

8. Comprehensive protection functions: self-recovery input under-voltage protection; self-recovery input over-voltage protection; input current limit protection; output over-voltage protection with lock (power off); self-recovery output short-circuit protection; output soft start.

Function and field:

In general, there are two situations in which the power supply grid voltage has Problems:

A) The AC voltage is unstable, fluctuating continuously.

B) The AC voltage continues to be low or high for a long time. Both of these situations are not conducive to the normal operation of the electrical equipment, and it is easy to cause the electrical equipment to burn out in serious cases.

There are generally three reasons for power supply voltage problems:

1) There is a problem with the generator voltage regulator in the power plant, resulting in a problem with the output voltage. Such are generally small hydropower plants.

2) There are problems with the performance of power transformers in substations or substations, especially those that are in serious disrepair and aging.

3) The total power consumption in the region greatly exceeds the power supply load, resulting in a continuous low power supply voltage, and even a low power supply frequency in severe cases, which will paralyze the power grid and cause large-scale power outages!

Widely used: large-scale electromechanical equipment, metal processing equipment, production lines, construction engineering equipment, elevators, medical equipment, embroidery textile equipment, air conditioners, radio and television equipment in the fields of industry, agriculture, transportation, post and telecommunications, military, railway, scientific research and culture, etc. All electrical occasions that require voltage regulation, such as household electricity and lighting.
