The Significant voltage fluctuations that occur on the electrical network simulates the premature ageing of the critical machines and even damages them in most cases. The solution to this type of problem is the use of voltage stabilizers which guarantee that the connected loads will always operate within safe limits that will not damage them and the regulated voltage enables the machines to operate at a better efficiency thereby avoiding energy loss.
Advanced Micro Controllers today, the base for the new generation power conducting devices, provides a highly precise correction and regulation with auto calibration feature. Its instant response and smooth drive outputs enhances the performance ofthe entire correction system.
“Miracle Stabilizer’s” unique single screen and key pad enables the user to grasp faster, the input and output status of all the phases and to read input & output voltage, current and frequency within seconds.
