CT-317: Photovoltaic (PV) current clamp 1000 V, 2000 A

CT-317: Photovoltaic (PV) current clamp 1000 V, 2000 A

CAT III / CAT IV current clamp for self-consumption PV installations. It can measure impedance, capacitance, temperature (optional), frequency, diodes and it enables transferring data through USB.


Thanks to its specifications (1000 V, 2000 A), the CT-317 current clamp is perfect to work in self-consumption PV (photovoltaic) installations, both in private residential environments, buildings and other locations. It is a CAT III (1000 V) / CAT IV (600 V) protection class measurement instrument.

Just insert a microSD card in the memory slot to store measurement records with an user-definable time between samples of 2 to 7200 seconds. The system accepts cards of up to 32 GB (an 8 GB card is included).

The CT-317 current clamp has a built-in real-time clock to attach the day and time to the measurements, transfer them to the computer and process them with any compatible application.
