The ACS 2000, ABB’s active front end drive for general purpose applications, is now available with higher power capabilities, up to 3,000 hp. Developed with the latest drive technologies, The ACS 2000 is suitable for general purpose applications where a medium voltage installation is required, such as pumps, fans, blowers and conveyors. Users across many industries, including water, wastewater, power, cement, mining and HVAC, can all derive significant energy savings as well as more reliable process control while benefiting from the drive’s compact, lightweight design.
 
The ACS 2000’s direct-to-line connection means it’s transformerless, resulting in a small footprint for space-sensitive applications. The design is packed with innovative technology such as a high voltage IGBT based active front end and patented multi-level switching topology, providing both line and load friendly operation. The ACS 2000 design provides near sinusoidal current and voltage waveforms making the drive compatible for use with standard NEMA rated motors.
 
The installed base for the ACS 2000 of both 4kV and 6kV ratings continues to expand in nearly every country in the world with the release of the third 4kV frame size. In addition to the expansion in power ratings, additional pre-engineered options such as a fused input contactor with disconnect and an auxiliary power transformer have been added to the product line.

“In working with many customers in the field, we’ve found areas to enhance our offering, such as adding a configurable disconnect that can provide a further integrated solution,” added Jeff Peterson, central region sales manager drives and controls. “Our scalable approach to the ACS 2000 is more than just increasing our power range, but giving customers further flexibility while leveraging a tried and true technology platform.”

The ACS 2000’s drive control platform uses ABB’s award-winning DTC, resulting in high torque and speed performance as well as other unique functionalities such as power loss ride-through. Control of the drive is immediate and smooth under all conditions. By actively managing power factor, the ACS 2000 DTL can maintain unity power factor across the entire speed range of the drive while providing valuable energy savings to the end user. In addition, the AFE enables regenerative operation which feeds back braking energy into the line supply, further reducing overall energy consumption.

The ACS 2000 medium voltage drive is a natural fit with ABB’s Baldor-Reliance medium voltage motor range.“Our motors and drives have been tested and matched in an optimally packaged solution for rotating machines and intelligent control,” offered Johan Karlsson, managing director of ABB’s large motor and generator business in the United States. “Very few companies can offer a singular solution that gives the customer a high quality motor-drive package from one supplier, manufacturing both products right here in the United States.”
