EC-3A-RS Three Phase Current & Energy Logger

Ideal analysis logger for Energy Audits
The affordable Electrocorder is the best value solution for carrying out site audits, with great analysis and reporting tools in our free software.  Our focus on providing an easy to deploy energy analyzer with built-in equipment management tools helps to make logging as effective as possible.  Tamper-proof setup means that installers or other personnel can't casually change or view logging parameters and invalidate data.                

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.  Averaging period can be set from 1 second to 60 minutes (301 days).  Many other loggers will only take data snapshots, meaning that you miss crucial trend data.

Industry Standard
Electrocorder is the market leader in energy and power analysis and fault diagnosis, used to troubleshoot and resolve customer complaints by electricity network suppliers throughout Europe such as Dalkia, SSE, Electricity North West, ESB Networks and NIE Networks.  Supplied Worldwide to utilities, industry and electrical contractors.  Acksen has been designing and manufacturing Power Quality Loggers since 1994, using our expertise to provide highly robust and reliable equipment - so much that we're prepared to offer a free lifetime warranty on all our Loggers (conditions apply).

Perfect for Load Surveys/Feeder Loading Analysis
The EC-3A-RS is used by power distribution companies, heavy industry, facilities management, electrical or site services and maintenance engineers to monitor loading variations on site helping them to diagnose any related issues, transformer and feeder sizing problems. Ideal for gathering data to make a case for splitting-up the loading or increasing circuit capacity.  Available in 5kA or 10kA variants on request for larger sites!

The EC-3A-RS is a three-phase current data logger that just needs its 3 flexible Rogowski coils 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 fit easily 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 view below - please note that in the video below the model used is the forerunner of the CT-3A-RS which uses CTs rather than Rogowski coils.
