Features and advantages of SJW3 three-phase fully automatic servo voltage stabilizer
- Precise voltage regulation: Composed of single-phase TND series high precision voltage stabilizers, it adopts a three-phase phase-shifting method to ensure that the output of every phase voltage is stable. It’s applicable for three-phase four-wire input. The output can adopt three-phase four-wire or three-phase three-wire connection mode flexibly.
- Real-time voltage monitoring: three independent ammeters display the output current of each phase, and the output voltage of each phase can be switched by a commutation switch to be viewed via a voltmeter.
- Fast Response: The automatic sampling control circuit detects grid voltage fluctuations in real-time, driving the servo motor to make quick adjustments and ensuring a continuous and stable power supply.
- No distortion of the waveform: During the output voltage regulation, the waveform of the current is not distorted; thus, equipment safety and reliability are guaranteed, which makes it possible to work continuously for a longer period.
- Multi- protection functions: Built-in delayed start, overvoltage, undervoltage protection, and other functions make it possible to effectively avoid voltage abnormalities, which may cause damage to the equipment.
- Wide application: Applicable for all kinds of power equipment that have strict requirements on voltage stability to guarantee stable and safe operation of production equipment.
- This servo voltage stabilizer could be an ideal choice for industrial equipment, power systems, and various instruments. Such equipment will be run smoothly and effectively in a complicated power grid environment.
