What Is a Power Supply Regulator?

The power supply regulator ^[1] is a power supply circuit or power supply device that can automatically adjust the output voltage. Its role is to stabilize the power supply voltage with large fluctuations and unsuitable electrical equipment within its set value range. The circuit or electrical equipment can work normally at the rated operating voltage.

Power regulator is a kind of power supply circuit or power supply equipment that can automatically adjust the output voltage. Its role is to stabilize the power supply voltage with large fluctuations and unsuitable electrical equipment within its set value. The equipment can work normally under the rated working voltage. Voltage stabilizers can be widely used in electronic computers, precision machine tools, computed tomography (CT), precision instruments, test equipment, computers, industrial and mining enterprises, oil fields, railways, construction sites, schools, hospitals, post and telecommunications, hotels, scientific research and other departments. Elevator lighting, imported equipment, production lines and other places that require stable power supply voltage. It is also suitable for users at the end of low-voltage distribution networks with low or high power supply voltages and large fluctuations, and electrical equipment with large load fluctuations. It is particularly suitable for all voltage-stabilized electrical places that require high grid waveforms. The high-power compensation type power regulator can be connected to firepower, hydraulic power and small generators.

The power regulator consists of a voltage regulator circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate to change the position of the regulator's carbon brush Through automatic adjustment

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

2. The combination of high-efficiency supercapacitors and switching power supply systems, smooth and intelligent work, and effective protection of automotive batteries.

3. Stable voltage output, eliminating the impact of voltage fluctuations caused by the internal resistance of the battery and the wire during large dynamic work, so that the audio and video system can work stably at the high end of the rated voltage range, and maximize the power output and dynamic range of the amplifier.

4, low ripple output, effectively suppress power supply noise interference.

5. Low impedance, strong instantaneous dynamic response ability, strong bass, mellow midrange, and treble transparent. Power requirements.

6, high power (when 12V input, the power is 360W

) To meet all original audio and video systems within six channels

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

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

In general, there are two cases of problems with the power grid voltage:

A) The AC voltage is unstable, fluctuates, and fluctuates continuously.

B) The AC voltage continues to be low or high for a long time. These two situations are not conducive to the normal operation of the electrical equipment, and are likely to cause serious burnout of the electrical equipment.

There are generally three reasons for problems with the supply voltage:

1) There is a problem with the power plant's generator voltage stabilizing device, which causes problems with the output voltage. This type is generally small water

Power station.

2) There are problems with the performance of power transformers in substations or distribution stations, especially those that have been out of repair for years.

3) The total power consumption in the area greatly exceeds the power supply load, causing the power supply voltage to continue to be low.

A low frequency of power supply has paralyzed the power grid and caused a large-scale power outage!

Widely used: large mechanical and electrical equipment in the fields of industry, agriculture, transportation, post and telecommunications, military, railway, scientific research and culture,

Metal processing equipment, production lines, construction engineering equipment, elevators, medical equipment, embroidery and textile equipment, air conditioners,

Radio and television and household electrical appliances, lighting, and other electrical applications that require voltage stabilization.

LW-SBW compensation

Basic structure :

The motor is used to drive the carbon brush to slide between the windings of the self-sustaining transformer to directly adjust the output voltage or adjust the output voltage through a compensation transformer.

Film regulators are widely used in large-scale electromechanical equipment, metal processing equipment, production lines, construction engineering equipment, elevators, medical equipment, embroidery and light textile equipment, air conditioning , Radio and television and household electricity, lighting and other places that need voltage stabilization.
