Emerson Control Techniques
Control Techniques is a leading manufacturer of AC and DC variable speed drives, servos and power conversion technologies for commercial and industrial applications. Their innovative products are used in the most demanding applications, requiring performance, reliability and energy efficiency.
These AC drives provide world-class solutions to the widest range of applications and industries. Their drives offer:
- Wide power and voltage ranges
- High performance motor controls
- Extendability through a large range of click-in SM-Option Modules
- Compact size
- Robust design for long and reliable service
The current trend is to replace DC systems with new AC drives and motors to reduce maintenance overhead. This can, however, often be a significant task that requires the machinery to be taken out of service for an extended period while mechanical and electrical rework is completed. Utilizing existing DC motors and upgrading the DC drive is often the most attractive option. Control Techniques DC drives are now based on our industry-leading AC drive technology to deliver enhanced motor performance, reliability and system options.
Soft starters are a simple and economic method of controlling AC motors for fixed speed applications. Traditional methods of starting motors such as across-the-line (ATL) or wye-delta, result in increased machine wear through rapid acceleration and deceleration phases of operation. The Digistart product combines advanced control features with simple installation and commissioning.
