Are these the world's most advanced softstarts?
Control Techniques says its compact Digistart range includes many advanced features. The compact Digistart range comprises of two product families, the ultra compact Digistart CS for induction motors up to 110kW, and the Digistart IS, perhaps the world's most advanced soft starter, for induction motors up to 800kW.

"The Digistart products are a competitive addition to our range of drives and will enable our customers to benefit greatly from the Control Techniques' application knowledge of both soft starters in standalone installations and when used in combination with inverter drives," says Product Manager Jeff Ford.

The Digistart CS version is said to be amongst the most compact soft starters on the market. It is easy to use, configured in seconds using simple rotary switches, yet 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 what the company claims to be industry-leading motor control, with several start methods available including constant current, current ramp and new, advanced 'adaptive control'. The latter provides a high level of control over acceleration/deceleration by enabling the user to select the ideal 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. One application where this is a significant benefit is in pumping where it can be used to eliminate annoying and damaging water hammer effects.
