This AC Active Power sensor measures AC power up to 7500W. Powered by an external 12VDC power supply, the AC Active Power Sensor provides a 0 to 5VDC analog signal that is linearly proportional to the power measured.

The AC Power Sensor can easily be mounted using the screw holes, or on a 35mm wide DIN rail for quick installation. The terminal blocks accommodate conductors of up to AWG #16. The window in the Sensor has a diameter of 6.5mm.


  • Measure up to 1250W of AC power
  • Snaps on to standard 35mm DIN rail
  • Connects to a Phidget Interface or Hub through an adapter

The power sensor connects to an analog input on Phidgets I/O boards. The formula to translate the output voltage into Power is:

P(W) = (Vout – SensorOffset) * 250

To determine the offset in your system, record the output voltage when there is no power applied to the sensor. Use that value in the place of SensorOffset in the formula above.


You can use a 12V sensor adapter to connect this sensor to your InterfaceKit or Hub. See the Connection & Compatibility tab for more details.

Mounting Suggestion

Warning: The AC Power Sensor needs to be attached in parallel with the line voltage. This requires cutting and using loose ends of high power cables. ALWAYS be sure to turn off the power running through the cables while manipulating and before cutting the cables. When attaching the cables, be sure to follow your country’s wiring code to ensure safe installment of the sensors and to reduce the risk of injury and fire. If you are uncomfortable, consult with a certified electrician.


12V Sensor Adapter


This power sensor requires a 12V power supply and outputs a 0-5V signal depending on the power measurement. For a simple way to provide 12 volts, you can use our 12V sensor adapter. It uses the 5V supply from your InterfaceKit or Hub and steps it up to 12V while simultaneously passing the 0-5V signal from the sensor into the Phidget cable.

To connect the sensor, connect the terminals as follows:
