Industrial Inverter systems are used for rugged environments and designed particularly to safeguard critical loads in industrial applications. An galvanically isolationed transformer is used to isolate load from input supply. Otherwise, voltage transients, created by degraded mains supply, can seriously damage both inverter and the critical load.


The inverter converts DC voltage into pure sinusoidal AC voltage with constant amplitude and stable frequency. The unit works with an IGBT inverter bridge with PWM (pulse width modulation) having high efficiency in the partial load range as well as achieving a low distortion factor at non-linear load. Inverter output encompasses 6 IGBT modules, boosting the instant power capacity of the inverter by double fold with comparison to regular systems. This feature allows the inverter to handle higher capacity loads (inrush currents) with smaller capacity devices. In addition, switching at high frequency – 16KHz – keeps the output sin wave (THD) undistorted providing reliable solutions for nonlinear loads. On LCD panel all measurement values, real time base events and failures can be viewed and communicate remotely with RS485 port.
