Product Overview


Product Description

1.It adopts high efficiency discharge load and special steady current mode, high accuracy of constant current, fast response, environmental protection and no peculiar smell.
2.Discharge current, voltage protection lower limit, discharge time and other parameters can be set freely, the whole process constant current current discharge, no jump, when reached the voltage lower limit set value or discharge time to automatically stop discharge, can also be manually quit discharge at any time
3.Various self-protection functions: reverse connection, wrong connection, under-voltage, over-voltage, undercurrent, over-current, over-temperature, fan abnormal
4.with the "wireless battery patrol instrument" supporting the use of real-time collection of the voltage of each single battery, set the relevant parameters can achieve the automatic discharge of the whole process
5.LCD screen, real-time display of the data, intuitive and easy to use
6.Data communication interface: USB, RS485, Convenient online use and export data
7.Built-in memory automatically save discharge data, support power off save
8.The instrument is equipped with simple and practical background analysis software, which can perform data check and analysis, report printing, automatically generate curves, histogram, data tables, etc. Excel format file can be exported, which is convenient for data processing and reporting.
9.It’s small and light and can be carried by one person, easy to
use, safe and reliable.

Our Advantages

Schematic diagram of three-stage charging process
Stage I: Constant-current limit voltage charge. 
Stage II: Constant-voltage limit current charge.
Stage III: Floating charge.

The principle of "stepped" constant discharge electricity
1.Simple principle of constant current, good effect,good expansibility, fast response speed, high steady current accuracy .
2.The current loop adopts pure resistance, stable and reliable performance, and environmental protection without peculiar smell;
3.Different resistance/power values can meet the requirements of different voltage and current ranges;
