Solid State - Modulated Wave Stabilizer

Sai Electricals with its customer centric approach and continuous R&D has brought about a revolution with the launch of Powerware EEZ.

Powerware EEZ is a Modulated Wave stabilizer based on state of the art Pulse Width Modulation (PWM) technology using latest generation IGBT semiconductors, which maintains constant output voltage for an easy and comfortable ride, even during severe voltage fluctuations.

Power fluctuation causes motor inefficiency, overheating and burning of motors, high consumption in lighting loads, failure of bulbs, chokes and electronic equipment, malfunctioning of CNC machines and computer loads.

Powerware EEZ senses the fluctuations in the input voltage on real time basis. Instantaneously the IGBT, with a switching time of less than 0.5 micro secs, generates a PWM sine wave of exact magnitude required to be added to/ subtracted from the line voltage and feeds it to the primary of a series buck/ boost transformer. The buck/ boost transformer superimposes this sinewave to the line voltage, without any waveform distortion, to provide a constant and smooth output voltage.

Powerware EEZ is housed in an indoor enclosure with following inbuilt protections :

Powerware EEZ works best with properly earthed neutral. In case of a floating neutral, it is strongly recommended that the neutral be grounded to minimize the float. Alternately an Isolation transformer may be installed.
