Siemens launched a new enclosed drive system, the SINAMICS G120XE, designed for the demands of industrial pump, fan and compressor applications.

Built around the SINAMICS G120X infrastructure drive, this new enclosed system is used for fast design and commissioning in industries such as oil-and-gas/petrochemical, water/wastewater, power plants, industrial climate control, refrigeration and chillers in harsh environments.

A NEMA 1 enclosure is standard, with a NEMA 12 version optional, featuring appropriate ventilation and air filters. The base enclosure is suitable for wall-mounting to 75 hp applications, while the free-standing floor module accommodates uses to 200 hp.

Standard electrical characteristics of this enclosed drive system include a UL508A listing, SCCR rating to 65kA, circuit breaker disconnect with flange-mounted operator handle and mechanical door interlock, plus control power transformer for internal power control and power module with PWM IGBT inverter.

The enclosure ventilation fans on the SINAMICS G120XE are controlled via a relay and run only as needed.

Communications with higher level SCADA and PLC systems is possible via PROFINET or EtherNet/IP with additional communication options available like PROFIBUS, MODBUS RTU and BacNet MS/TP.
