CT-3A-RS Electrocorder Three Phase Current Logger for Industry and Light Commercial

The CT-3A-RS is a three-phase current data logger that just needs its clamp-on current transformers connected to your incoming supply. Setup the Logger using the Electrosoft software, then fit it to the distribution board or other point that you're going to measure.

As no voltage input is required, you can easily fit as a competent person without necessarily requiring an electrician or engineer, and may not require any power interruption at all. Once you're set up, just press the Start button to start logging! The onboard indicator will flash Green when logging.

When the logger's finished recording (or you've captured enough data!) Just disconnect from supply, hook it up to your PC and download the information. Electrosoft will let you view the data immediately on-screen and save or export for later analysis.

For a demonstration of how to use the logger, please watch our video below.

Designed for extended Volt-free Logging
Operates on replaceable batteries for up to 3 months of volt-free logging when needed, with optional external power input for extended life. Rugged and reliable, with IP65 environmental sealing as standard!

Never miss data with Constant Sampling
Constant Sampling ensures that you never miss any data, with minimum and maximum values ​​displayed across the averaging period. Records for up to 50 days to EN50160 standard.
