Digistart, the new electronic controller from LEROY-SOMER, part of Emerson Industrial Automation, for induction motors, integrates the latest technological changes including an optimized bypass function. Digistart is available in two ranges adapted to market requirements, the D2 range, 18 to 200 A of compact starters; and the D3 range, 23 to 1600 A for advanced controllers.

According to LEROY-SOMER, this exceptionally compact solution offers total control over start-up and a response to energy saving requirements. Digistart is ideal for upgrading existing installations, and enables the linking of delta connection motors, which advantageously replace a star/delta start-up, and uses the 6 motor power supply cables. Additionally, this enables a saving of at least one rating size in controller dimensioning.

Digistart can operate with 200-440 V, 200-575 V or 690 V three-phase networks. It can also control several induction motors coupled in parallel as well as a collector ring motor. Available on D3 (ratings 360 to 1600 A), the power inputs and outputs may be installed on request above and/or under the starter, according to the layout of cables in the cabinet. Digistart thus optimizes installation in the cabinet.The available field bus modules are: Modbus RTU, port USB, DeviceNet and Profibus.

In addition, Digistart proposes the latest electronic control technology, including start-up and stopping self-adapted to load, automatic optimization of parameters by machine learning from start-ups. It also includes a slow-down curve dedicated to pumping applications resulting from 15 years of LEROY-SOMER's experience and know-how. With Digistart, LEROY-SOMER proposes compact, economic, high performance and communicating controllers, which are better integrated into industrial installations and enable substantial savings to be made.
