ACT400-10 AC Motor Control

ACT400-10 AC Motor Control

ACT Series

The ACT series drive delivers the features and benefits of a microprocessor based drive and the low cost of a triac control. The ACT output is a variable voltage with a constant frequency, making it perfect for a small speed range control of a single phase AC motor, such as a permanent split capacitor (PSC), shaded pole, synchronous, and universal motors. Unlike other common triac drives, the ACT series drive takes advantage of single phase motor characteristics to provide approximately constant pressure in filtered fan applications, meaning as a filter becomes clogged, the motor will speed up to maintain airflow. The ACT series drive also has an internal closed loop circuit meaning the drive can maintain motor voltage during AC line sags or swells. It also accepts feedback in the form of a thermistor or voltage signal to create a PI loop.

Potentiometer Kit 202-0096 is included with a purchase of the ACT400-10

* Output frequency is constant and equal to input line frequency. The ACT400-10 can only vary the output voltage, therefore applications requiring speeds below 75-80% of motor's rated speed should use a variable frequency drive, not a triac.


  • ACE Footprint and Compact Size: Traditional ACE mounting pattern with smaller footprint uses minimal space
  • Microprocessor Based: Allows custom programming for OEMs
  • Auto Ranging Input: No voltage switches to set
  • AC Line Voltage Compensation: Holds a steady output voltage even if the input voltage fluctuates
  • Variety of Motors: Permanent Split Capacitor (PSC), Shaded Pole, Synchronous, and Universal
  • Feedback: Optional PO closed loop or thermistor feedback
  • Low Cost: Triac drives are a cost effective alternative to a traditional VFD
