SBW Compensation Voltage Stabilizer Regulator

As a mature SBW compensation voltage stabilizer regulator manufacturer, our Yibaling factory also offers customized services for products. Welcome to place your order.

This product, unlike the electronic type which achieves rapid switching through power devices, adopts a core structure of servo motor drive carbon brush + voltage regulator, achieving smooth, stable and reliable voltage correction.

Its working principle is straightforward and efficient:

Once a deviation is detected, the Voltage Stabilizer Regulator instructs the servo motor to precisely move the carbon brush to the position on the ring-type auto-transformer winding. It continuously changes the turns ratio of the compensation winding to inject or cancel the missing/excessive voltage in real time, thereby stabilizing the input voltage with a fluctuation range of ±15% to a high-precision output within ±1%.

Thanks to its electromagnetic structure, our SBW Compensation Voltage Stabilizer Regulator can easily withstand the instantaneous large current impact caused by motor startup and welding machine operation, and will not be burned out due to load sudden changes. It is especially suitable for complex load scenarios such as heavy industry and mines.

This Voltage Stabilizer Regulator adopts the linear compensation principle, without chopping or step changes, and the output is a standard sine wave, without generating additional harmonic interference, and is friendly to precision instruments and inductive loads.

Technical Features

The core technical features of the SBW Compensation Voltage Stabilizer Regulator can be summarized as a precise and reliable continuous stepless compensation system based on a servo motor. The system abandons the rapid switching mode of electronic switches and returns to the stable path based on the classic electromagnetic structure.

The control center will issue instructions to the precise servo drive system. Subsequently, its servo motor drives a special alloy carbon brush made of silver-graphite composite materials through a deceleration mechanism.

The carbon brush rotates on the ring-shaped winding of a self-coupling transformer with high-purity oxygen-free copper wire as the core and high magnetic permeability silicon steel sheet as the core.

This physical position change adjusts the turns ratio of the compensation winding in real time and linearly, thereby achieving a stepless and smooth voltage correction.

This unique working principle directly shapes the two indispensable core performance advantages of the SBW Compensation Voltage Stabilizer Regulator:

Absolute purity of output waveform: Due to the linear electromagnetic compensation, the output is a perfect sine wave, completely without the harmonic pollution commonly seen in switching power supplies, friendly to the power grid, especially suitable for precision instruments, medical equipment and inductive loads that are sensitive to power quality.

Outstanding shock load capacity: The product's power core is a robust electromagnetic component, rather than a fragile semiconductor power transistor. Therefore, it can easily withstand instantaneous overloads up to 2-3 times the rated current, such as the start-up of large motors, the operation of welding machines, without damaging or shutting down due to protection, demonstrating true industrial-grade resilience.

It also has an extremely wide input voltage adaptation range (standard ±15%, customizable to ±30% or even wider), integrates a complete set of protection functions such as overvoltage, undervoltage, overcurrent, short circuit, phase loss, mechanical limit, carbon brush wear warning.
