Telemecanique Altivar 61 and Altivar 71 variable speed drives is characterized by the extent of its power range, a feature that enables control of asynchronous motors from 0.37 up to 630kW for voltages of 200 to 240V AC and 380 to 480V AC. The Altivar 61 variable torque offer dedicated to pump and fan applications supplement the Altivar 71 constant torque offer. Their functions combined with open loop and closed loop performance provide a solution to meet the requirements for complex and/or high power machines (materials handling, hoisting, wood machines, process machines, textile machines, packaging, pumps, multipump, fans, etc).www.schneider-electric.com
