This Altistart 48 soft start/soft stop unit is a controller with 6 thyristors used for torque-controlled soft starting and stopping of three-phase asynchronous motors. It offers soft starting and deceleration functions along with machine and motor protection functions, as well as functions for communicating with control systems. It works at a rated supply voltage from 230V to 415V AC and up to 250A rating. Altistart 48 torque control enables starting without mechanical stress and smooth control of hydraulic transitions, with a single acceleration ramp making adjustments is quick and easy, whatever the load. If connected in the motor supply line it is suitable for motors with power rating up to 132kW (at 400V) for standards applications and 110kW (at 400V) for severe applications. If connected to the motor delta terminals it is suitable for motors with power rating up to 220kW (at 400V) for standards applications and 160kW (at 400V) for severe applications.
To be discontinued.
