150KVA Three Phase Servo Voltage Stabilizer 380V (±30%) input model is a three-phase compensation with high-precision regulator, cabinet type. Further more, It comes with LED digital display design and also compensated structure voltage regulation. In addition to this, It is mainly composed of voltage regulation transformer and compensation transformer. Besides, it is also characterized by enough power that can achieve relatively large power and maintain high precision output.

In addition to what has been mentioned above, the input voltage range (especially the minimum voltage) is very wide. The regular voltage stabilizer cannot handle extreme low and unbalance voltage but this models can handle them conveniently. Furthermore, even if those can reluctantly work, the output is de-rated a lot due to low voltage and high current situation. A special voltage stabilizer with a step-up transformer can somehow solve the problem, but it has the disadvantages of high cost, low efficiency and more space occupation.
In addition, our specially designed PRAG series of 150KVA Three Phase Servo Voltage Stabilizer 380V (±30%) input, adopts patent regulator that copes with low input voltage, and output voltage regulated to rated 220V without de-rated input power. Similarly, its high cost effective, reliability, high performance and long lifetime are all backed by a world class manufacturer with decades of mains power experience. Subsequently, It is applied for any load like telecom, medical, industrial and household applications.
100KVA Three Phase Servo Voltage Stabilizer Applications
Above all, the Prag 150KVA Three Phase Servo Voltage Stabilizer 380V (±30%) input, is widely used in lots of places and not limited to industries and mining enterprises, printing companies, machine tools, post and telecommunications business, railways, construction sites, schools, hospitals, hotels, defence ministries, scientific research centres and other departments of electronic computers, precision machine tools, precision instruments, experimental devices, elevators and production lines.
