The RCZD28-18 aviation charging and discharging power supply is designed for battery bank maintenance, integrating charging and discharging into one unit, and can be widely used 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.
Compact and lightweight, featuring a digital display for easy operation and high intelligence. The charging process is automatically completed in three stages: constant current, equalizing charge, and floating charge after setting the charging parameters. Similarly, the discharging process is automatically completed in constant current mode after setting the discharging parameters.
