One Xtraordinary infrastructure drive system


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

SINAMICS G120XE is an engineered enclosed variable speed drive system designed specifically to meet or exceed  the demands of industrial pump, fan and compressor applications. Built around the flexible, function-rich and easy to setup & use SINAMICS G120X drive. the system is available in NEMA 1 and 12 configurations  and UL listed to UL508A. Depending upon power ratings, the drive enclosure is either a wall-mounted box or a free-standing 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.
