Three Phase Voltage Data Logger, P/N: SL-3V

Miniature 3 Phase Logger

The SL-3V is a three phase data logger ideal for industrial logging. The stored data is uploaded to a PC via the supplied RS-232 cable.

Why is the Electrocorder better than other similarly priced competitors? The Electrocorder range use a constant sampling technique, unlike the single reading of competitors. When the loggers start to record, they sample every channel 16 times per cycle, a cycle is 16ms at 60Hz and 20ms at 50Hz. At the end of each averaging period, 3 quantities are saved for each channel, the True RMS average, the Max, which is the highest cycle value during the period and the Min, lowest cycle value. This means that it will record all the peaks and troughs which are one cycle or longer.

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

The voltage levels are stored with dates and times. With the back-up battery, the Electrocorder can continue to record for a year.

When the logger has been returned to the power company, the stored data is uploaded to a PC via the supplied RS-232 cable. Using Electrosoft, the recorded voltage levels, dates & times can be viewed in both tabular and graphical form, exported to a spreadsheet or saved to file.
