Overview of SBW-GD Microcomputer Controlled Radio and Television Special Voltage Regulator:
The specialized voltage regulator for broadcasting and television is our company's dedicated transmitter equipment, which has accumulated years of experience and is the result of scientific research, design, and manufacturing. Due to high-frequency interference from transmitter equipment and radio frequency interference between lines and ground, a large amount of harmonic current is injected into the power grid, causing distortion of AC sine waves. Generally, analog control and analog instruments will inevitably produce control and measurement errors. Radio and television dedicated voltage regulator, controlled by digital circuit microcomputer (CPU), with flexible parameter settings, easy operation, and unique anti radiation interference. A shielding protective cover is installed on the control circuit board to avoid radiation causing the control system to "lose control". The machine is equipped with a lightning protection system, which can solve the lightning protection and surge problems in the radio and television room. It can be equipped with dual power input and multiple output, and has complete functions. This product implements digital circuits and uses color screen liquid crystal (LCD) display, with true RMS sampling and display, effectively overcoming the phenomena of "loss of control" and "distortion". This voltage regulator is stable and reliable, making it the preferred voltage regulator for broadcasting and television equipment.
