PLEASE NOTE: Effective 2019, we no longer supply Control Techniques variable frequency drives and components. We have drives from several other manufacturers which can meet or exceed the performance characteristics of the Control Techniques line. Simply complete the form below, or contact us with the model of your current or obsolete Control Techniques drive and we’ll be glad to identify a suitable replacement.

Also, the Fincor and Saftronics lines of AC variable frequency drives, DC variable speed drives, and reduced voltage starters were once owned by Emerson but have been obsolete for several years. However, we have many years’ experience working with these drives and can quickly identify replacements capable of exceeding the quality and performance of these older drive technologies. For a suitable replacement, fill out the form below or contact us with your drive or application requirements, and we’ll handle it from there!

OVERVIEWControl Techniques Commander SX NEMA 4X Washdown AC Drive.

Dirt, dust, water, pollution. All environments that can mean additional cost whenever a ariable speed drive is needed. From wash-down food and drink applications to dust and other airborne particles such as in a textile plant, Control Techniques have designed the perfect match for such rugged applications – Commander SX. The Commander SX from 0.5 HP to 10 HP (.37 to 7.5 kW) is a Nema 4X (IP66) protected drive that enables users to mount the drive directly next to the motor giving significant cabling, cabinet and installation savings. The practicality of mounting the drive near the motor, while being protected from the harsh environment, brings users the additional benefit over integrated motors/drives by separating the two technologies in the event of maintenance and breakdown.

  • 0.5 to 5.0hp (.37 to 3.7kW), 30 230VAC .0.1 to 10hp (.25 to 7.5kW), 30 460VAC
  • Nema 4X IP66 enclosed drive – no need for separate enclosure
  • Designed for direct to wall or next to motor mounting – avoiding cabling, ( and installation costs
  • Easy set up and commissioning – the first ten parameters cover 80% of applications
  • More than 8 preset drive configurations
  • Surface textured and rounded corners designed to maximize washdown effectiveness
  • Internally fitted EMC filter (to generic and drive standards) for units up to 5hp (4kW), with externally fitting IP66 filters above (4kW)
  • Robust industrial housing with simple speed control interface
