Strong Points
Function
TF flexible current sensors measure the load currents of an electrical system and send the data to meters and PMDs via an RJ12 plug-and-play output. Thanks to a wide measurement range, TF current sensors cover the full current range of 150 to 6000 A with 7 references. TF flexible current sensors can be used with DIRIS Digiware, DIRIS A-40 DIRIS B, and ISOM Digiware F-60 via a quick RJ12 connection.
Advantages
Plug & Play
- A quick RJ12 connection makes wiring easy and reliable and prevents wiring errors. This also allows automatic detection of the sensor type and rating/transformation ratio.
- The sensors can be installed in both directions.
Accuracy according to IEC 61557-12
- Class 0.5 for the overall measurement chain (PMD + TF current sensors) from 2 to 120% of nominal current In.
- Accuracy is guaranteed regardless of the position of the conductor in the loop.
Secure locking
The locking system prevents loop opening and guarantees sensor function and accuracy even in harsh environments.
Installation
The TF flexible current sensor range has been specially designed for existing installations with major integration constraints or high-intensity currents.
Simplified installation
- The TF sensor electronics are built in to the RJ12 cable for quick and easy installation (no need for DIN-rail mounting) inside electrical panels.
- The integrator is self-powered by the PMD via the RJ12 cable and does not need an external power supply.
