Electrocorder Model: PV-3 Vdc G PV-3 Solar irradiance, 0-1500W.m-2 PV system output Vdc to 300V PV system output Idc to 300A ldc Vdc 300V IP65 Monitor charging circuits, PV (photovoltaic) cell, DC motor, and many other applications. Data stored in non-volatile memory. Complete with Electrosoft energy analysis software Memory capacity of 32,000 (True RMS) values per channel (10bit), up to 300 days continuous recording. Sealed to IP65/NEMA 12/4 Selectable averaging period from 1 second to 60 minutes. Accuracy: 1V – 5V < 2% of reading 6V – 60V < 1% of reading 60V – 300V ~2% of reading Kit includes data logger, fused voltage input leads, DC current probe, pyranometer, USB lead, 12Vdc PSU, Electrosoft software and a carry case. 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. Electrocorder Model: PV-3 The PV-3 is specifically designed to accurately monitor one DC voltage channel, 1V to 300Vdc and one DC current channel -10A to +10A, -100A to +100A. This allows you to monitor charger performance and PV (photovoltaic) cell output, as well as many other applications like DC motors. peaks and troughs which are one cycle or longer. Setting up the Electrocorder PV-3 is easy, suitable for non-technical staff. Using the supplied (free) Windows software, Electrosoft, input the location details for the logging and choose the logging period. Electrosoft will print the necessary dispatch/ return documentation including user instructions. All data is included in a database of dispatches and returns, allowing you to track the location of multiple loggers. The recorded data is uploaded to a PC via the supplied USB cable. Using Electrosoft, the recorded current levels with dates and times 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. These results may then be discussed with the customer. Why is the Electrocorder better than other similarly priced competitors? The Electrocorder range uses 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. 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, the lowest cycle value. This means that it will record all the The voltage and current levels are stored with dates and times. With the backup battery, the Electrocorder can continue to record for up to a year. On the logger, recording is signified by a flashing green light. A red light advises users that the unit has completed recording. The PV-3 has a current range ±10A & ±100A.
