AirCare Automation is proud to announce the availability of its new, updated VariPhase Single-Phase AC motor controllers. The new VariPhase units enhanced features that will make speed control of a single-phase PSC motor easier and more consistent.

The Drives come in three voltages:

120 volt             230 volt            277 volt

Several model numbers in each voltage span motor rated currents up to 20 Amperes to cover the majority of your single-phase PSC needs.

Enhanced performance

The VariPhase can now be used for:

  • Analog Input (or Manual) or Network (MODBUS RTU)
  • Open-Loop (Analog (0-5v) or Manual control) or Closed Loop
  • Analog Feedback signal of TACH feedback  

The version 7 platform has expanded the TRIAC firing angle curve into 1000 data points providing significantly more possibilities for your 100 point curve selection and eliminating "dead spots."

Enhanced Closed loop controls- better PID control loop and new optional closed loop adjustment tools provide a more robust closed loop experience for your fan control needs.

Analog Input "scalable range"- allows any type of feedback sensor (i.e. dual directional sensors) and still gets full input feedback range from your sensor.

Customized firing curves- Don't like the response to the analog/ manual set-point vs. speed control in open-loop mode?  The VariPhase™ firing angles can be adjusted/ customized for your needs based upon your input.
