② High output precision: the output voltage is very precise to the rated one, with precision of ±2%.

③ Fast response speed: the regulated power supply reacts quickly to voltage change, and transform the voltage to the final voltage fast.

④ Sound and stable performance: the equipment works soundly and stably, with low risk of malfunction.


3. Product Description
This product is a regulated power supply, with rated capacity of 50KVA. The input voltage of this electrical equipment is 304VAC to 456VDC while the output voltage of it is 220VAC. It is composed of two major parts: stabilizer and transformer. It firstly stabilize the voltage at 380V when the city power fluctuates within 304V to 456V. Then 380V would be transformed to 220V immediately.


The product features in high precision, fast reaction rate, strong electricity conductivity, stable and reliable performance, high quality parts, delicate design, full capacity, no waveform distortion, and low noise etc.
