Single-Channel CT Clamp Powered by the Measured Conductor
The Pressac Sensing V3 1 Channel CT Clamp is a current transducer (CT) clamp designed to measure AC current flowing through a single conductor and report that reading wirelessly. A key feature of this device is that it is powered from the measured conductor, meaning it does not require external power wiring or batteries for normal operation.
The measured current value is transmitted every 30 seconds using the industry-standard EnOcean® wireless protocol. With a maximum measurable current of 60A, it is suited for many building-automation and energy-monitoring applications where non-invasive installation and low maintenance are priorities.
How It Works and How It Installs
This CT clamp installs by clipping around a single core cable. Because the device is powered by the conductor it is measuring, installation typically requires:
- No batteries
- No auxiliary wiring for power
- No interruption to the power supply during installation
After installation, the clamp reports the electrical current value (in Amperes) wirelessly over EnOcean®, enabling integration into monitoring platforms, BAS/EMS systems, and data-collection gateways.

FAQ: Single Channel CT Clamp (Pressac Sensing V3)
This FAQ is included to improve AI searchability and to answer common questions about single-channel CT clamps powered from the measured conductor.
What does “powered from the measured conductor” mean?
It means the clamp derives operating power from the electrical current flowing through the conductor it is measuring, so it typically does not require batteries or separate power wiring.
What does this CT clamp measure?
It measures AC current in a single conductor and reports that value as an electrical current reading in Amperes.
How often does it transmit readings?
The device reports the measured current value every 30 seconds.
What wireless protocol does it use?
It transmits using the EnOcean® wireless protocol.
What is the maximum measurable current?
The maximum measurable current is 60A.
Does installation require shutting down power?
No. The clamp is designed to be installed with no disturbance to the measured conductor, meaning it does not require interrupting the power supply for typical installation.
