Schneider Electric Soft Starter, Soft Start, 45 kW, 415 V ac, 3 Phase, IP20

The Altistart 48 soft start soft stop unit is a controller with 6 thyristors which is used for the torque controlled soft starting and stopping of three phase squirrel cage asynchronous motors.

Providing machine and motor protection, the Altistart 48 series also offers users functions for communicating and control systems. The soft starter has high-performance algorithms which significantly contribute to its ruggedness, safety and ease of installation and set-up.

Exclusive Altistart torque control (patented by Schneider Electric)
Constant control of the torque supplied to the motor during acceleration and deceleration periods (significantly reducing pressure surges)
Facility for adjusting the ramp and the starting torque
Starter can be bypassed using a contactor at the end of the starting period whilst maintaining electronic protection
Wide frequency tolerance for generator set power supplies
Starter can be connected to the motor delta terminals in series with each winding

Built in motor thermal protection
Processing of information from PTC thermal probes
Monitoring of start time
Motor preheating function
Protection against underloads and overcurrents during continuous operation

4 logic inputs, 2 logic inputs, 3 relay outputs and 1 analogue
Plug in I/O connectors
