Think SINAMICS G120 inside the box


SINAMICS G120E NEMA 1 or 12  enclosed drives

SINAMICS G120E 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 is offered with three variants on the line side:  Standard 6-pulse,   Clean Power 18-pulse non-regenerative diode front end, and efficient Infeed with Innovative IGBT based technology for power regeneration to the supply system. SINAMICS G120E drives are UL listed to UL508C, and are available with optional Seismic Certification
