Giới thiệu Bảng Mạch Chuyển Đổi 3 Cổng Usb Dc-Dc 9v / 12v Sang 5v 8a

description:
The module has 2 USB protocol charging ports and 1 non-protocol charging USB port. The maximum output current is 4A. With overcurrent protection function. The USB protocol charging interface can automatically identify the type of charging device and shake hands with the device through the corresponding USB charging protocol to obtain the maximum charging current, saving charging time while protecting the charging device. It can charge most mobile phones in the market such as Apple and Samsung.

parameter:
Input voltage: DC 5.6-14V
Output voltage: DC 4.8-5.6V adjustable, default 5V
Maximum output current: 4A
Output overcurrent protection: If the output current is greater than 4A, the output will be stopped immediately
Input overcurrent protection: input current is greater than 2A, immediately stop output
Short circuit protection: Yes
Built-in protocol: Divider1/Divider2/Divider3 charging protocol (for Apple); D+/D– set to 1.2V mode (for Samsung); BC1.2DCP and CTISYD/T1591-2009 charging protocol
Product size: 38*39mm

Instructions for use:
There are three USB ports on the module. The label "Auto 2.4W" means that the USB port automatically recognizes the type of charging device, and "noIC" means that the USB port does not recognize the charging device. Devices that require an agreement to charge, such as iPhone, can only be charged through the "Auto 2.4W" USB port.

The input voltage range of the module is within DC 5.6-14V, the maximum output current is 4A, and the module automatically turns off the output when it exceeds 4A. In order to protect the subsequent modules, there is a 2A resettable fuse at the input. If the input current exceeds 2A, the fuse becomes high-impedance and the output is turned off. Therefore, if the output current is relatively large, the input voltage should be appropriately increased and the input current should be reduced. For example, to output 5V 3A, the input voltage should be greater than 7.5V (3A*5V) /2A).

The module has an adjustable potentiometer, which can adjust the output voltage (4.8-5.6) V±0.3, and the adjustable range may be different for different input voltages.
