The RCD28-18 Aviation Charging and Discharging Power Supply is designed specifically for battery pack maintenance, integrating charging and discharging functions. It is widely applicable in communication base stations, power, and power stations. It achieves the charging, discharging, activation, and repair processes for the entire battery pack or individual cells.
This unit is compact and lightweight, featuring a digital display for easy operation and high intelligence. After setting the charging parameters, it can automatically complete the charging process in three stages: constant current, balanced charge, and floating charge. For the discharge part, setting the parameters allows for an automatic discharge process with constant current.
