Under the load state, the voltage and current setting method are simpler than
that under the power state. The user needs to connect an external DC power
supply capable of outputting 0V ~ 10V between the voltage setting pin 1 (Vol_
Pro), current setting pin 17 (Cur/Vol_Pro) and ground wire 3/4/5/6 (AGND). Oth-
er analog input pins should also be connected correctly. The wiring method is
shown in the figure below.
7.8 Anti-reverse connection module function
(optional)
When the user connects the battery and executes the battery charge and dis-
charge test, select the IT-E118 anti-reverse connection module to realize DC re-
verse connection protection, surge suppress, and sense reverse connection
protection.
The output terminal on the rear panel of series instrument can be optionally con-
figured with IT-E118 anti-reverse connection module, which can realize the fol-
lowing functions:
•
Anti-reverse connection of the DC output terminal
•
Isolated from the wiring of the energy-storage DUT
•
Surge suppress
•
Sense reverse connection protection
The dimension figure of the IT-E118 anti-reverse connection module is as
follows:
