1.Measurement of Battery percentage and remaining battery AH number.
2.Measurement of DC  bidirectional current and DC voltage.
3.Measurement of DC  bidirectional power.
4.Measurement of DC  bidirectional accumulative electric energy.
5.Over voltage alarm function, parameters can be set by yourself. (With alarm sound, alarm output CN2)
6.Low voltage alarm function, parameters can be set by yourself. (With alarm sound, alarm output CN2)
7.Over current alarm function, parameters can be set by yourself. (With alarm sound, alarm output CN2)
8.Low electricity alarm function,the electricity icon will flash constantly, prompting the user to charge. (With alarm sound, alarm output CN2).
9.Battery over temperature alarm function, parameters can be set by yourself. (With alarm sound, and the alarm output CN1 can be used to control the battery cooling fan. Note: All control output signals are weak signals, and the drive equipment needs to be amplified by the customer's external amplifier circuit for control.)
10.Store data when power off.
11.Hall sensor isolation type measurement,more safe and reliable, easy to install.
