STB 1Kva-12Kva Single Phase Servo Wall Mount Avr For Low Voltage

The DTB series servo voltage stabilizer is an efficient single-phase voltage stabilization device designed for home use. This series provides two control modes: relay and servo control to meet different user needs. Equipped with a color LED display, it can display the input voltage, output voltage, undervoltage, overvoltage and overload status in real time to ensure that users are aware of the power situation in a timely manner. The DTB series voltage stabilizer has a compact structure and a wall-mounted design, which is convenient for installation on the wall of the home.
