Telemecanique Altistart 48 Soft Starter- 60 to 200hp. Series ATS48C21YU. 208/230 V to 440/460/575 V. The ATS48 Soft Start is a controller with 6 thyristors. It is used for the torque-controlled soft starting and stopping of three-phase squirrel cage asynchronous motors within the power range. It offers soft starting and deceleration functions along with machine and motor protection functions as well as functions for communicating with control systems. These functions are designed for use in state-of-theart applications in centrifugal machines, pumps, fans, compressors and conveyors, which are primarily used in the construction, food and beverages and chemical industries. The high-performance algorithms of the ATS48 controller contribute significantly to its robustness and ease of setup. (ACN31)(H10)
