Technical specifications

Electrical, mechanical and integration data

Input voltage: DC 4.5V~24V
Input limiting current: 3.25A
Battery charging voltage: 5-16.8V（Adaptive smart battery charging voltage demand）
Battery charging current: 0~5A（Adaptive smart battery charging voltage demand）
Output current: 5A MAX
Standby current: DC input power on：＜20mA（（DC input） DC input power off：＜1mA（Battery end）

NVDC (Narrow Voltage DC) Default mode: Battery removal：VSYS=VMIN（Vmin is powered on at 12.5V by default, and automatically updates after inserting the battery: 5V/2S，9V/3S，12V/4S） Battery insertion：VSYS=VBAT
PTM (Pass Through Mode) Using PTM mode, the load current should be <3A: Battery removal or Battery Full charge：VSYS=VIN Battery working：VSYS=VBAT
UPS (Uninterruptible Power Supply): Vload=VIN（system load and DC input are connected to VIN. When the DC input is powered off, the power supply board reversely supplies power to VIN, which is generally 12V. For other voltages, please contact Guishi for customization）
