• · 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 208V to 690V AC and up to 62A 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.
• · It is suitable for motors with power rating up to 50hp (at 575V) / 45kW (at 690V) for standards applications and 40hp (at 575V) / 37kW (at 690V) for severe applications.
