The CT-3A is specifically designed to accurately monitor one, two or three current channels allowing you to monitor the loading and/or balancing problems and energy consumption of an installation.

The current levels are stored with dates and times. With the back-up battery, the Electrocorder can continue to record for 2 months. An external 12Vdc PSU input is available, to allow for prolonged logging without batteries.

The recorded data is uploaded to a PC via the supplied USB lead. Using Electrosoft, the recorded current levels, with dates and times that can be viewed in both tabular and graphical form, exported to a spreadsheet or saved to file. Graphs can be printed showing the recorded levels and the allowable tolerance bands.

The CT-3A-RS has two user selectable current ranges 0.5Aac to 40Aac and 4Aac to 400Aac. If you require a higher current ranges of up to 3kAac, consider the EC-3A-RS.
