nergy production in mining operations requires precise, reliable motor control on a continuous 24/7 basis, often under very difficult conditions. Drives are vital for pumps, conveyors and crushers in mining. Any breakdown causing lost production can be very costly, thus making reliability and uptime a top priority.
To meet these demanding requirements, ABB has developed the new ACS800-38
low-harmonic drive. By completely rethinking traditional designs, the standard container with the
drive and added air-conditioning unit can be replaced with a high-reliability, all-in- one turnkey ACS800-38 solution built on a much smaller footprint.
Key benefits and advantages of the new low-harmonic drive include:
■ Specific focus on high uptime and reliability, even in the weak power networks that are common in remote locations.
■ Completely new cooling tecÚology with no external air reaching the drives, so drive maintenance and changing of air filters is reduced.
■ Robust components for reliable operation and long life in climates like hot sandy deserts and harsh mines.
■ A compact, easy-to-move thermally-isolated enclosure that can be transported and installed without difficulties by forklift or crane.
Te ACS800-38 integrates an active supply unit and low-harmonic filter that effectively eliminates harmonic issues, without need for additional filtering equipment or multi-pulse transformers. Tis low-harmonic drive also maintains unity power factor for maximum efficiency.
