An AC Drive, which is also known as Inverter and Variable Frequency Drive (VFD) or Variable Speed Drive (VSD), is used to drive an AC motor running in variable speed. Siemens is the leading manufacturer of electric drive technology. With its universally accepted SINAMICS family of low voltage AC drives, you will experience the world’s broadest spectrum of general performance, high performance, component, distributed, and enclosed solutions for addressing any industrial motion application, which includes pumps, fans, compressors, conveyors, mixers, mills and extruders.
SINAMICS V20 – Easy-to-use drive for basic motion
The compact SINAMICS V20 is the easy drive for simple motion sequences, which is surprisingly versatile, features quick commissioning times, robustness and energy efficiency. It covers a power range extending from 0.16 to 40 Hp (0.12 to 30 kW), with 7 different frame sizes. The SINAMICS V20 is designed to focus on reducing engineering, commissioning and operating costs.
SINAMICS G120X – Infrastructure pump, fan and compressor drive
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. It covers a wide performance range of 1 to 700 Hp (0.75 to 630 kW)
SINAMICS G120 – Modular Vector Drive
The SINAMICS G120 family of closed-loop vector drives (complies with NFPA 79-2007) offers high levels of integrated safety, energy savings, and network connectivity. SINAMICS G120 comes in 3 voltage variants for connection to 200, 400 and 690V with power ratings from 0.5 to 400 Hp (0.37 to 250 kW). The EN 60204 safety functions of the SINAMICS G120 are fully integrated into the drive and include Safe Torque Off, Safe Stop 1, Safety Limited Speed and Safe Brake Control. As a result, production plants obtain greater levels of safety while requiring less overhead to integrate the drives into fail-safe, automation, and drive environments.
SINAMICS G120C – Compact vector drive
SINAMICS G120C has been specially designed for customers looking for an economic, space-saving and easy-to-operate standard AC drive, while also providing a surprisingly wide range of functions. With its 7 frame sizes, the SINAMICS G120C covers a performance range of 0.75 to 150 Hp (0.55 to 132 kW). This device combines compactness with superior power density and is characterized by fast installation and commissioning, user-friendly connections and easy-to-use operating tools.
