Soft starters from Control Techniques

April 2010 Motion Control & Drives

Digistart is Control Techniques’ flexible soft starter range for motor control and protection in constant speed applications. The Digistart range combines advanced control features with simple installation and commissioning. It can be used in a wide range of industries and applications including:

* Pumps.

* Compressors.

* Fans.

* Material handling.

* Machinery automation.

* Mining and aggregate.

* Forestry.

Benefits of using a soft starter

Soft starters are a simple and economic method of controlling AC motors for fixed speed applications. Traditional methods of starting motors such as direct-on-line (DOL) or star-delta result in increased machine wear through rapid acceleration and very high peak currents. Soft starters solve this problem through controlling the acceleration and deceleration phases of operation.

Control Techniques’ Digistart family offers two levels of functionality to meet all soft starter requirements.

Digistart CS

Digistart CS is a compact soft starter for motors up to 110 kW (200 A). The Digistart CS offers comprehensive motor protection features and is quickly commissioned using simple rotary switches.

Digistart IS

Digistart IS is an intelligent soft starter offering many advanced features for motors up to 800 kW (1600 A). These features include ‘adaptive control’ which provides an unprecedented level of acceleration and deceleration control, and an intuitive plain language display for configuration.
