Electrocorder DC-3VA DC Voltage Current Data Logger

The DC-3VA DC Voltage Current Data Logger is a two-channel data logger is specifically designed to accurately monitor one or two DC voltage channels, 1V to 300Vdc and one DC current channel, allowing you to monitor PV (photovoltaic) cell output, DC charger performance, as well as many other applications – like DC motors. The stored data is uploaded to a PC via the supplied USB cable.

  • DC-3VA-TH has a range of ±10A to ±100A
  • DC-3VA-TT has a range of ±30A to ±300A
  • DC-3VA-HT has a range of ±100A to ±1kA

The kit includes data logger, fused voltage leads, DC current probes, USB lead, 12Vdc PSU, Electrosoft software and a carry case. IP65 rated enclosure.

When recording, the Electrocorder will store the average DC voltage and DC current over the period chosen (1 sec to 60 min), it will also record the highest (max) & lowest (min) values during that period.

The advantage of Electrocorder products over most others is that our Data Loggers constantly sample information
(recording the Minimum, Maximum and Average reading) over the set period. Many other products only take ‘snap shots’ of what is going on and can miss 99.9% of the data that is critical to your analysis.
