The main technical parameters and performance of the equipment

Device channel number【The whole machine has a total of 160 channels】

Work flow control method【Unified control of the whole machine】

Charging mode【Constant current, constant voltage】

Charging cut-off condition【Voltage, current, time, capacity】

Discharge mode【Constant current】

Discharge cut-off condition【Voltage, time, capacity】

Protective function  【Over-voltage protection, under-voltage protection, over-current, under-current, over-capacity protection, reverse connection protection, power-off protection, data breakpoint recovery (that is, when the incoming power continues to work, it can continue to work at the data point at the time of the power outage).

Voltage disconnection protection function. If the voltage line is broken, the device can also collect the battery voltage through the jumper resistance between the current line and the voltage line to prevent the battery from overcharging and overdischarging. The connection line (such as the current loop) is protected against poor contact. 】
