Control Techniques has launched its compact Digistart soft starter range.

The range comprises two product families, the ultra-compact Digistart CS for induction motors up to 110kW, and the Digistart IS for induction motors up to 800kW.

The Digistart CS version is configured in seconds using rotary switches and provides comprehensive motor protection, so that no external devices are required.

It features a built-in bypass contactor that eliminates the need for external bypass contactors and reduces heat dissipation and energy losses by bridging out the power devices once the motor is at full speed.

This feature saves panel space and often allows the use of non-ventilated enclosures.

The intelligent Digistart IS version provides motor control, with several start methods available including constant current, current ramp and adaptive control.

The latter provides control over acceleration/deceleration by enabling the user to select a suitable start/stop profile for the application.

Adaptive control then monitors the motor performance by analysing each start/stop and adjusting accordingly to maintain optimum control.

The Digistart IS features a multi-language user interface with inbuilt start-up wizards for ease of commissioning, real-time performance monitoring and informative event logs.

All parameters are viewed in real engineering units and can be displayed numerically or graphically.

The user interface is IP65 rated and can be mounted remotely.

Models up to 110kW (220A) feature an internal bypass contactor.

Both Digistart CS and Digistart IS support optional network communications with Profibus, Devicenet and Modbus RTU protocols.
