Product Advantages

Each of 16 channels operates with a single point independent constant current and constant voltage source, stable and shock-free during mode transitions. Supports start, stop, pause, continue and protection functions.

Charge/discharge modes: Constant current, constant voltage, constant current constant voltage/constant current, constant power, constant resistance. Charging cut-off conditions: Voltage, current, time, capacity, △V. Discharge cut-off conditions: Voltage, time, capacity. Process settings: 64 process step parameters and 256 cycles can be set.

Protection functions: Overvoltage protection, undervoltage protection, overcurrent protection, undercurrent protection, overcapacity protection, power failure protection, data breakpoint recovery.

Graphical operation interface displays voltage, current, time, capacity and other data of each battery simultaneously with color-coded working status and abnormal conditions. Real-time detection and display of each battery status. Modular design, easy to maintain.
