Standard PITE 3926C battery data logger unit composes of the followed parts:

>>>Cell DAC
Cell DAC (Data Acquisition Case) is for monitoring voltage of each cell. With 2 color coded serial ports, each Cell DAC could be connected with 4 cells of 12V (or 6V), and 12 cells of 2V (or 1.2V). For different battery system, number of cell DACs will vary accordingly. For example in 48V system in telecom, it will need 2 Cell DACs if it is 24 cells of 2V. Cell DAC is powered by batteries with DC12V±15%. With built-in wireless communication module, value of cell voltage could be received directly in PC.

>>>String DAC
Connected with two ends of battery string, String DAC is for monitoring string voltage, string current and ambient temperature. Each String DAC will come with a customized current sensor for testing string current. Each PITE 3926C Data Logger will only need ONE String DAC which also include built-in communication module for wireless communication.


>>>Communication terminal and RS232-USB converter
It is communication terminal connected with PC via a RS232-USB converter. With the communication terminal, PITE 3926C PC software will receive monitoring data directly and easily.

>>>Computer (Optional)
For software installation, data monitoring, testing result analyzing and test reporting generation.

Order information
NOTE: All above standard units also include 1 string DAC, 1 communication terminal, 1 RS232-USB converter and PITE 3926C DataView software.
