The Altistart 48 soft start/soft stop unit is a controller with 6 thyristors used for torque-controlled soft starting and stopping of three-phase squirrel cage asynchronous motors for power ratings between 4kW and 900kW.
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 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.
The high-performance algorithms of the Altistart 48 contribute significantly to its ruggedness safety and ease of setup.

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 on the electrical distribution system by reducing line current peaks and voltage drops during motor starts

The Altistart 48 soft start/soft stop unit offer comprises 2 ranges
- three-phase voltages 230Vac to 415Vac 50/60Hz
- three-phase voltages 208Vac to 690Vac 50/60Hz

In each voltage range the Altistart 48 soft start/soft stop units are sized for standard and severe applications.
The Altistart 48 soft start/soft stop unit 1 is supplied ready for use in a standard application with class 10 motor protection.

It comprises an integrated display terminal which can be used to modify the programming -- adjustment or monitoring functions in order to adapt and customize the application to meet individual customer requirements.

Drive performance functions
- 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)
- ease of adjusting the ramp and the starting torque
- option of bypassing the starter using a contactor 3 at the end of the starting period whilst maintaining electronic protection (bypass function)
- wide frequency tolerance for generator set power supplies
- option of connecting the starter to the motor delta terminals in series with each winding

Machine and motor protection functions
- built-in motor thermal protection
- processing of information from PTC thermal probes
- monitoring of the starting time
- motor preheating function
- protection against underloads and overcurrents in steady state

Functions to ease integration into control systems
- 4 logic inputs + 2 logic outputs + 3 relay outputs and 1 analog output
- plug-in I/O connectors
- function for configuring a second motor and easy-to-adapt settings
- display of electrical values -- the state of the load and the operating time
- RS485 serial link for connection to Modbus serial link
