Think SINAMICS G120 inside the box


SINAMICS G120E-2 NEMA 1 or 12  enclosed drives

SINAMICS G120E-2 is a range of configurable enclosed variable speed drives for a broad spectrum of industrial applications, based on SINAMICS G120 modular drive components. The drives are air-cooled and available in NEMA 1 or NEMA 12 (ventilated) enclosures. All models utilize a motor side IGBT inverter with PWM technology. SINAMICS G120E-2 is offered with three variants on the line side:  standard 6-pulse, SINAMICS G120E-2 drives are UL listed to UL508A.
