Description

Optional Cell Data Logger (CDL)
Each CDL is recording voltage of up to 12 cells for all cell types (1.2V, 2V, 6V and 12V). It has wireless communication with K-900 main unit and PC. Kongter also offers customized CDL for non-standard battery types. CDL numbers are easily expandable to cover more battery volumes.

CDL can work with SDL (String Data Logger) without load bank for monitoring of cell voltage, string voltage, temperature and current in the same software.

Its Connection:
Each CDL is connected with 12 cells of 1.2V, 2V, 6V or 12V. Therefore, different battery systems will require different amount of CDLs.

Kongter Powerful PC Software
All standard load units of K-900 come with PC software. It could remotely control the load bank via wifi and have a real-time monitor for the whole process of discharge, analyze the measurement data and easily print out detailed test report. Same PC software is also compatible for Kongter’s whole series battery test equipment.

Q: What industries is the battery load bank applied for?
A: Kongter covers various industries with its wide range customer-tailored battery/DC load bank models. It includes telecom, power utility, data center, forklift battery maintenance, industries manufacturing and many others. For details, please download the data sheet with more info. 

Q: Can I test the battery systems in short time?
A: Depending on different regulations, you could alternatively discharge batteries based on C5, C10 or C20. Shorter discharge time will require higher discharge current for the same unit. Kongter also offer some customized load units with high discharge current. For details, please contact us with your requirement. 
For quick test of batteries to pick up weak batteries from whole string, we will also recommend BT-301 Battery Condition Analyzer for measurement of both battery internal resistance and conductance. Test  can be done in seconds. 

Q: How do I record voltage of each cell in the string effectively?
A: Kongter offers optional Cell Data Logger (CDL) for each load bank model for recording voltage of each cell in real time during battery load test. With CDL, you could also use the PC software to monitor all measurement data during battery discharge.

Q: What voltage rating does the CDL support?
A: Standard CDL is designed for measurement of 1.2V, 2V, 6V and 12V cells with connection of up to 12 cells each CDL. Default CDL quantity is calculated based on common cell types of 2V, 6V and 12V. Measurement of 1.2V will require more CDLs for same load bank model. Other non-standard cell types including lithium batteries are optional. 

Q: Can I use PC software for data monitoring if there is no CDL with my load bank?
A: Yes, you can. However, you will not see voltage of each cell. And all measurement data is saved in the load bank automatically even if there is no connection with PC. You could also view the data in load bank during discharge.

Q: If I do not have CDL, what battery type can I discharge?
A: You could discharge any type of battery if there is no CDL as long as string nominal voltage fit your load bank. 

Q: Can the CDL work independently without load bank?
A: Yes, it can work along with SDL (String Data Logger) to make another product, the BDL-3927 Battery Data Logger. It will be using same PC software for data monitoring.

Q: Can Kongter’s load bank work with non-Kongter load banks?
A: Yes, if you have requirement to discharge higher current than max current of non-Kongter load bank, you could use “Assistant discharge” function of Kongter load bank to increase discharge current.

Q: How do I use Kongter’s load bank to discharge at higher current?
A: Besides using another customized load model with higher current, you could also use parallel discharge of up to 5 units K-900 to increase the discharge current.

Q: I am a contracting company, can I have one single load model with wide voltage range for different industries?
A: Yes, Kongter offers load models of DLB-2348 and DLB-2415 with wide voltage range. If you have different requirement, you could also contact us with your requirement. Click HERE for helpful guideline on how to select the right load bank model.

Q: In the datasheet, I see that most load bank models can discharge down to10V. Does that mean that all load banks can discharge in wide voltage ranges?
A: All load banks can discharge as low as 1V. However, the discharge current at 1V will be pretty small for most models. If you have requirement to discharge at higher current in low voltage, you are suggested to send Kongter your detailed requirement including string nominal voltage and discharge current for each string. If you have different strings to discharge, list all of them.
