LD-FDY Battery Pack PTC Ceramic resistor touch screen Discha

We have successfully a line of extremely intelligent and accurate battery pack capacity testers (“tester”) that can serve as discharge loads and realize discharge with the set constant currents by means of continuous control over discharge currents. When the voltage of a battery pack or the voltage of a single battery of it is smaller than the set lower limit of voltage, or the set discharge duration or the set discharge capacity has reached during discharge, the tester will automatically stop discharge and record the real-time data of all valuable and continuous process.

The voltage information of single batteries monitored by the tester is subject to wireless repeater access that is simple, secure and accurate.

Product Features

The PTC ceramic resistor avoids the red hot phenomenon, making the whole discharge process safer;

1、The internal controller includes two CPUs for the highest safety, stability and accuracy in testing so that a CPU can sound an alarm and shuts down the tester upon failure of the other CPU;

2、Thanks to the all electric isolation technology, the discharge part can still operate normally in the case of strong electromagnetic interference or strong power interference;

3、The tester has a 2G memory and supports a U disk up to 32G;

4、The tester has functions such as check capacity test, discharge suspension, parallel load test and online compensated discharge for diversified occasions;

5、The tester can upload discharge data to a U disk via its USB interface and import them to a host PC so that the data management software on the host PC can analyze the discharge and generate corresponding data reports, making data uploading easier;

6、The tester is subject to intelligent single chip microcomputer ARM control and has a 7″touch screen LCD supporting menu operation and Chinese and English display;

7、The tester supports automatic protection: When the set discharge duration or the set discharge capacity has reached, or the voltage of battery pack is smaller than the set minimum or the load wiring is abnormal, the tester will automatically stop discharge, sound an alarm and record the shutdown mode;

8、The tester supports the setup of discharge stop conditions, including battery pack’s final voltage, discharge capacity and discharge duration to make the discharge test safe;

9、The tester supports online compensated discharge and discharge tests for batteries in online service with help of external pincerlike current sensors, making discharge tests convenient. (This function is especially applicable to an occasion with only one emergency battery pack.)
