2.3. Performance parameters
Control mode:
The charge-discharge process of all kinds of batteries could be set and the parameters are
automatically controlled, which could reserve the charge formula.
Running mode:
Constant current charging, constant voltage and limiting current charging, constant current
and limiting voltage discharging, cycling, etc.
Protection:
Reserving data when there is over-current, over-voltage, current-cutting and power off. It
could automatically recover when power on and provide phase break protection.
Phase transformation:
Setting time, voltage, current etc.
Record:
Recording the charging data, voltage-current curve, wrong information and operation record.
Rectifying mode:
Three- phase full-bridge controlled rectifier
Cooling mode:
Self cooling or air cooling
The accuracy for stable current and voltage: the accuracy for stable current and voltage is less
than
±
0.5%
The accuracy for time:
＜
30S/24h
Operating mode instructions:
Constant current charging: setting charging current. Transition has two modes: time and
voltage
Constant voltage and limiting current charging: setting controlled current value and
controlled voltage value. Transition has two modes: time and current
Cycling: setting the charging steps from one to five. Inside could loop and nest.
Note:
please find the specific setting modes in the chapter of touch panel operating
instruction.
