The S/DBW-H series single-phase and three-phase high-precision fully automatic AC voltage stabilizers use a ring-type transformer disc structure for the voltage regulating system. It is composed of a contact-type autotransformer voltage regulator, a servo motor, and an automatic control circuit. When the mains voltage is unstable or the load changes, the automatic sampling stabilizer control circuit sends a signal to drive the servo motor, adjusting the position of the autotransformer voltage regulator's carbon brush, so that the stabilizer output voltage is adjusted to the rated value and reaches a stable state.

This series of stabilizers features a lightweight structure and phase-by-phase voltage adjustment function. When combined with a step-up and step-down transformer, the product is very suitable for imported CNC numerical control machining systems, precision instruments, and other fine processing equipment with smooth current fluctuations. It is also suitable for office, lighting, and air conditioning environments in households. This series of stabilizers offers a wide variety of models, full specifications, and an attractive appearance. It features undistorted waveforms, high efficiency, reliable performance, and long-term operation. The stabilizer is equipped with short-delay, over-voltage, and other protection functions. According to user requirements, long-delay and under-voltage protection functions can also be added. It is an ideal economical voltage stabilizer, ensuring the normal operation of your electrical equipment.
