Altistart Soft Starters

Type:  Controller
Description:  The Altistart 48 soft start/soft stop unit is a controller with 6 thyristors that is used for the torque-controlled soft starting and stopping of three-phase squirrel cage asynchronous motors in the power range between 4 and 1200 kW. 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-the-art applications in centrifugal machines, pumps, fans, compressors and conveyors, which are primarily to be found in the construction, food & beverage, and chemical industries. The high-performance algorithms of the Altistart 48 contribute significantly to its robustness, safety and ease of setup.
Connectivity:  Modbus
Features:  The Altistart 48 soft start/soft stop unit is a cost-effective solution which can reduce machine operating costs by reducing mechanical stress and improving machine availability; reduce the stress placed on the electrical distribution system by reducing line current peaks and voltage drops during motor starts. The Altistart soft start/soft stop unit offer comprises 2 ranges: three-phase voltages 230 to 415 V, 50/60 Hz, and three-phase voltages 208 to 690 V, 50/60 Hz. In each voltage range, the Altistart soft start/soft stop units are dimensioned for standard and severe applications. It comprises a built-in terminal that can be used to modify programming, adjustment or monitoring functions to adapt and customize the application to meet individual customer requirements. Drive performance functions; Machine and motor protection functions; Functions facilitating the integration of the unit into control systems.
Specifications:  RS 485 on RJ 45; 4800 to 19200 bps
