Siemens Answers with SINAMICS G120E NEMA 1 or 12  Enclosed Drives

SINAMICS G120E

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

  • 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.  Scroll down for more details.

6-pulse diode front end with power module PM240

Power Range

1 to 200 HP (0.75 - 132 KW) at 460 V AC

Features

Input line reactor

Integral braking chopper (requires external braking resistor)

 
18-pulse Clean Power diode front end with power module PM240

Power Range

50 to 200 HP (37 - 132 KW) at 460 V AC

Features

Always meets harmonic limits per IEEE 519-1992 at VFD input terminals

Phase shifting autotransformer and input line reactor assembly

Integral braking chopper (requires external braking resistor)

 

Efficient Infeed with power module PM250

Power Range

25 to 125 HP (18.5 - 90 KW) at 460 V AC

Features

The line side Efficient Infeed provides the ability to feed energy back into the supply system to break the load without wasting energy in a braking resistor. This saves space, eliminates wiring and reduces heat losses.

Efficient Infeed technology uses an IGBT converter that provides reduced line harmonics, without needing a line reactor, for even more space savings and lower heat losses.
