High-Precision Automatic Power Supply Equipment
The control system uses advanced integrated circuits. The automatic sampling control circuit drives the servo motor, adjusting the carbon brush position of the auto-voltage regulator to maintain a steady output voltage.
Features
Carbon Brushes: Uses 1017 carbon brushes imported from Germany, providing anti-oxidation, high temperature resistance, corrosion resistance, energy savings, and high efficiency.
Servo Motor: Imported materials ensure long-lasting motor performance, which is crucial for the stabilizer’s operating life.
Microcomputer Control Panel: High-quality control board extends the stabilizer’s service life. Typically, single circuit board control is used, but dual computer control boards are equipped for stable 24/7 operation.
Stroke Control Switch: Provides overvoltage and undervoltage protection.
Panel and Finish: Features neatly routed components and first-class workmanship.
