Bangzhao Electric
1 / 2
Modular design, N+1 hot backup, and smooth expansion capabilities. The intelligent design achieves the following functions automatically via serial communication: module switch on/off, charging mode converting, output voltage setting, output current setting, and SYNC switch over. Equipped with a standard RS-485 interface for easy integration with automation systems, supporting "4-remotes" functions and CAN interface. Fully hot swappable for continuous operation.
Superior performance with efficiency exceeding 94%.
High power converter frequency, high stability, compact size, and light weight.
Isolation automatic current sharing technology with unevenness < ±3%.
Built-in output isolation diode and automatic protection mechanisms.
LED digit display, clear indication lights, and intuitive button operation.
