| 3516_0 - CE-P02-32BS3-0.5 AC Active Power Sensor 0-250V*0-5A (50Hz) |
Product Features
- Measures AC Active Power up to a maximum of 1250W
- Operates at 50Hz
- 0.5% Accuracy
- Isolation Voltage of 2500VDC
- DIN Rail mountable
- Connects to any device with an Analog Input.
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.
The current sensor connects to an analog input on Phidgets I/O boards. The formula to translate the SensorValue into Power is:
To determine the offset in your system, record the SensorValue when there is no power applied to the sensor. Use that value in the place of SensorOffset in the formula above.

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.

- 3024 – Power Supply 12VDC 2.0A (North American style plug)
- 3023 – Power Supply 12VDC 2.0A (European style plug)
- 3025 – Power Supply 12VDC 2.0A (UK style plug)
- 3022 – Power Supply 12VDC 2.0A (Australian style plug)
In order to use one of these power supplies with this sensor, you must cut the small plug from the end of the power supply and connect the wires directly into the sensor. You can also use a 3031 – Female Pigtail.
This sensor connects to any device with an Analog Input.
You can use the 3002 - Sensor Cable 60cm or the 3004 - Sensor Cable 350cm to connect the AC Power Sensor to your Phidget. Just snip off the connector from one end of the sensor cable and connect the white wire to the terminal marked with an 8, and the black wire to the terminal marked with a 6. The red wire is not used. You can also use a 3031 – Female Pigtail.
This is how you connect the AC Power Sensor to a Phidget Board that does not have 12V power supply, such as the 1018 or the 1203, using a Sensor Cable.
- Connect the Power Supply +12V wire (the wire with the white line) to the voltage sensor terminal 5 (+12V).
- Connect the Power Supply Ground wire and the Analog Sensor Cable Black wire to the voltage sensor terminal 6 (-).
- Connect the sensor cable white wire to the voltage sensor terminal 8 (0-5V).
- Feed one of the AC main wires carrying current through the window of the sensor and connect it to the voltage sensor terminal 1 (UL).
- Connect the other AC main wire to the voltage sensor terminal 3 (UN).

For boards that have power input, such as the 1019 or the 1072, if the supplied power is 12V, then the + terminal block on the Phidget Board can be connected to the voltage sensor terminal 5 (+12V), and the G terminal block on the Phidget Board can be connected to the sensor terminal 6 (-).
