SINAMICS G120X VFDs Archives

In developing the world’s leading equipment control for industrial solutions, Siemens continues to explore and develop new ways of making even the most basic processes more efficient and cost-effective.

From the immensely successful SINAMICS G120 family of drives, the G120X is an “infrastructure” drive targeted for pump, fan & compressor applications in the Water & Wastewater (W&WW), HVAC, irrigation/agriculture & industrial chiller/refrigeration segments.

SINAMICS G120X is simple, seamless, cost & energy efficient, robust, reliable and fit for digitalization. SINAMICS G120X easily integrates into existing applications, works with any standard motor (induction, synchronous and synchronous reluctance motor) and can be configured for cost-optimization and resource-saving operation which ultimately helps reduce total cost of ownership. It meets all the latest industry standards with regard to energy efficiency and product safety and offers enhanced safety with SIL3 rated safety functions and up to 100kA short-circuit current rating according to UL61800-5-1.

Cost- and energy-efficiency		Significant time-savings
•	Integral DC choke (FSA-G) eliminates the requirement of an external line reactor	•	Control unit has been redesigned:
•	Designed to deliver constant power at a current according to NEC table 430.250 at 3AC 480V and 600V, and at an operating temperature of 45ºC without derating, and up to 60 ºC (55 ºC with PROFINET, EtherNet/IP™ version) with derating	–	To accept 16 AWG (1.5mm ²) wire with removable connectors for easy and fast control wiring via pre-manufactured wiring harness
•	Increased motor cable lengths up to 450 meters (1476 ft)¹without output choke or filter	–	To allow 2x wire connections per terminal for certain terminals for ease of connections
•	New design feature enables UL Open Type / IP20 drive in to push through type using an optional add-on Push-Through (PT) kit ², which reduces or eliminates need for cabinet fans, associated components and wiring, and also facilitates cost efficient NEMA / UL Type 1, 12 or 3R designs with an appropriately NEMA / UL-rated external enclosure	•	Frame sizes A–C are redesigned to fit in the standard MCC plug-in type bucket
