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 110A 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 55kW (at 400V) for standards applications and 45kW (at 400V) for severe applications. If connected to the motor delta terminals it is suitable for motors with power rating up to 90kW (at 400V) for standards applications and 75kW (at 400V) for severe applications. It weighs 8.3kg and its dimensions are, 190mm wide, 290mm high, 235mm deep. It is designed for use in the most common applications for centrifugal machines, pumps, fans, compressors and conveyors, which are primarily to be found in the construction, food and beverage and chemical industries. It complies with IEC/EN 60947-4-2 standard and is certified CE, UL, CSA, DNV, C-Tick, GOST, CCC, NOM, SEPRO, and TCF. The Altistart 48 is connected directly to the Modbus bus via its RJ45 connector port, It can also be connected to Ethernet, Fipio, Profibus DP and DeviceNet networks via a module (bridge or gateway) to order separately. It is designed to be mounted in vertical position (+/- 10 °) on a panel, thanks to 4 fixing holes. Altistart 48 delivers high performance with its Torque Control System (TCS) for controlled starting and deceleration, an easy integration in enclosures and control systems. This range provides also continual improvement of your machine operation by reducing mechanical or hydraulic stress and limiting energy loss and temperature rise, plus more.
