Description
>>>Cell DAC
It monitors voltage of each cell. For different battery system, depending on different battery systems, each BDL-3926C model will require different amount of Cell DACs.
>>>String DAC
It monitors string voltage, string current and ambient temperature. Each String DAC will come with a customized current sensor for testing string current. Each BDL-3926C Data Logger will only need ONE String DAC.
>>>Communication Terminal
Connected with PC to collect data from Cell DACs and String DAC.

BDL-3926C Battery Data Logger is wireless monitoring device for string voltage, cell voltage, current and temperature. It works individually to reflect battery status or co-works with Kongter’s other battery test equipments like battery charger and K-3980 DC load bank. ETM’s Cellular 4G/3G/2G range of battery powered outdoor data logger/SMS alarm dialers are the right choice when it comes to ease of use, configuration and accurate alarming. DeltaBlue is a rugged IP67 battery powered data logger using 4G/3G/2G cellular connectivity to send logged data and SMS alarms to ETM's own cloud dashboard or a. This app enables the users to monitor and record the battery level continuously. The Windows 10 hardware with several batteries are supported and up to three batteries info is shown in the plots. Apparently, the app might not operate on the devices doesn't have a battery.

Q: Why do I need battery data logger?
A: 1. In IEEE regulation including IEEE 450, IEEE1188 and IEEE 1106, quarterly to semi-annual inspection for voltage, current and temperature are necessary for stationary battery.
2. Compared to other ways of data logger, BDL-3926C is automatically recording battery info in the PC software. It is more convenient and time saving for stationary batteries and non-stationary batteries like forklift/motive power batteries.
Q: What are the main compositions of BDL-3926C and what are their functions?
A: There are two essential parts, the Cell DAC and String DAC. Cell DAC is for recording voltage of each cell, while String DAC is for recording of current, ambient temperature and string voltage.
Q: How many pieces of each part do I need?
A: For different battery systems, you will require different amount of Cell DAC. Each string will require only one String DAC.
Q: Can the Cell DAC and String DAC used separately?
A: Yes, they are working independently to each other. Both Cell DAC and String DAC measure and send data to PC software via a control terminal that is connected with PC. You could use them together or separately as per your need.
Q: Can I use the DAC together with load bank or other Kongter’s products?
A: The Cell DAC is commonly applied along with K-3980 battery load bank and K-3986 battery charger/discharger/activator. With their PC software, you could see more detailed info about batteries.
Q: What battery types does BDL-3926C support?
A: Standard Cell DAC supports common cells including 1.2V, 2V, 6V and 12V cells. Customized cell types are available upon request. String DAC supports all battery types.
Q: How many batteries can I connect to with the battery data logger?
A: Maximally you could connect up to 256 cells in one String.
Q: Can I use the data logger for remote control or PC software only?
A: It is used in PC data recording only. If you need remote control, you could consider the BMS-3923 Battery Monitoring System.
