With the rapid development of China's broadcasting and television industry, the equipment in the machine rooms has evolved from analog to digital, and from tube transmitters to all-solid-state transmitters. The power supply quality requirements for broadcasting equipment have increased significantly. However, due to a series of issues such as frequent over/under voltage, lightning surge spikes, and severe power grid harmonics in the current power grid supply, these issues severely affect the normal operation of transmitter equipment.

Due to high-frequency interference from the transmitting equipment, as well as radio frequency interference between lines and between lines and ground, harmonic currents are injected into the power grid in large quantities, causing distortion in the AC sine wave. This inevitably leads to control and measurement errors in general analog controls and instruments. The SBW(S)-GD Microcomputer-Controlled Power Stabilizer is the result of years of experience in matching our transmitting equipment, a crystallization of research, design, and manufacturing. The SBW(S)-GD series voltage stabilization control system employs digital circuit microcomputer (CPU) control, featuring radiation interference prevention. A shielding protective cover is added to the control circuit board to avoid radiation causing the control system to "lose control." To meet the special industry requirements of broadcasting and television, the stabilizer is equipped with manual or automatic bypassing devices for direct power supply when maintenance is needed. Optional RS-232 serial port and parallel interfaces are available for remote control and monitoring of the stabilizer. The central control unit provides the following information and operations: 1. The stabilizer's operating status; 2. Alarm information; 3. Measurement data; 4. Stabilizer operation; various parameter settings are flexible and easy to operate; an anti-lightning system is installed internally to address lightning and surge issues in broadcasting and television rooms; an automatic switching device for dual power supply can be added to the input; multiple control switches can be added to the output to control the stabilization of multiple transmitters; comprehensive in functionality.

The SBW(S)-GD microcomputer-controlled power regulator stands out in actual applications for its stability, low energy consumption, and ease of maintenance. Our products not only overcome the aforementioned challenges but also enhance voltage regulation accuracy, leading to more refined circuit designs.
