Functional Features
Modular design, with each module having 8 independent channels.
Each channel can be arbitrarily set to modes such as constant – current charging, constant – voltage charging, constant – power discharging*, constant – resistance discharging*, direct – current internal – resistance testing*, and standing still, etc.
Each channel can detect different types of batteries and work completely independently in different modes without interfering with each other.
The channels have complete multi – level software and hardware protection.
There are independent hardware constant – current sources and constant – voltage sources.
Support over – discharge protection.
Support online correction of current and voltage accuracy, enabling users to “test while calibrating”.
