20KVA (225-456) 3-Phase Voltage Regulator
Description
Overview
In the first place, this 20KVA 3 Phase Stabilizer model is a three-phase compensation with high-precision regulator, cabinet type with LED digital display design and also compensated structure voltage regulation. Also, 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. For example, the low input voltage can be 88V (the rated line to neutral voltage is 220V) thus results in the electrical equipment cannot start and operate. Ordinarily, the common voltage stabilizer cannot handle extreme low and unbalance voltage. Thus, the output is de-rated a lot due to low voltage and high current situation even if those can reluctantly work. Therefore, 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.
On the other hand, our specially designed PRAG series extreme wide voltage stabilizer adopts patent regulator that copes with low input voltage, and output voltage regulated to rated 220V without de-rated input power. Thus, its high cost effective, reliability, high performance and long lifetime are all backed by a world class manufacturer with decades of mains power experience. Thus, this Stabilizer is applied for any load like telecom, medical, industrial and household applications.
