One Xtraordinary infrastructure drive system


SINAMICS G120XE configured enclosed drive for pump, fan & compressor applications

SINAMICS G120XE is an enclosed drive designed specifically for pump, fan and compressor applications.  The drive is based upon the SINAMICS G120X drive to best meet or exceed the demands of multiple industrial applications, the ambient environment and the power supply system.  The SINAMICS G120XE offers a NEMA 1 enclosure, is UL508A Listed, SCCR (short circuit current rating) 65kA and includes a circuit breaker disconnect with flange mount operator handle and mechanical door interlock.  Enclosure ventilation fans are controlled via a relay and run only as needed, a significant energy saver and noise reduction benefit. A key feature is the intelligent operator panel, IOP-2. for fast local setup, fault diagnostics and intuitive operation of the G120X, and simplifies the adjustment of settings during operation.

The only thing MINI about it is the size

Introducing the SINAMICS G120XE MINI 

Available as NEMA 12, 1 to 10 Hp (0.75 - 7.5 kW), like its bigger brother, the MINI includes special enclosure color, input surge protection, output reactor, analog I/O isolation, I/O Expansion, 3C3 environmental protection and all popular communications options.  However, the MINI reduces the height of the 1–10 Hp enclosures from 43 to 27 inches.


SINAMICS G120XE MINI is perfect for pump, fan and compressor users who still want a metal protective enclosure with a door-mounted keypad/display, a circuit breaker disconnect with an external operable, lockable flange handle. 


The enclosure is small enough to mount on or near the application motor, while still providing the protection of a NEMA metal enclosure.


What you need to know about SINAMICS G120XE

Attention to detail is evident in the design of the drive. For example, the enclosure ventilation fans are controlled via a relay to run only when needed, i.e. when the drive is running. Not only does this save energy costs, but it also reduces noise levels in the electrical room.

The most common standard options can be accommodated in the base enclosure. A few options including output filters and reduced voltage soft start (RVSS) bypass require an add-on or separate options enclosure.
