Continuous torque drive claims new
standards
The Telemecanique Altivar 71 continuous torque variable speed drive is claimed to set new standards for performance, ease of installation and use, safety and openness for integration.
Schneider Electric reckons that the Telemecanique Altivar 71 continuous torque variable speed drive sets new standards for performance, ease of installation and use, safety and openness for integration Available as a complete range from 0.37 to 500kW, the new drive has been designed with ease of installation and use in mind, having been created under the "Simply Smart" initiative from Telemecanique
