The AUNILEC INV series for industral applications offers a range of one- and three-phase inverters with IGBT power conversion bridge. The system has been designed to continuously supply extra-low harmonics AC current to critical loads. The integrated static switch can automatically perform quick switching operations on the DC line, in case of black-out only, to substantially increase the global efficiency; it can also perform an ON-LINE conversion, in which the wave form is always generated by the inverter, thus ensuring a stable, undistorted waveform. The fast control system and the high-frequency PWM technology allow to connect the inverter to non-linear loads with a very low waveform distortion. The graphical display allows to show an easy to understand one-line diagram displaying the current status of the inverter and of the static switch, thus providing an accurate overview of the alarms and measurements.
