Bảng Mạch Hạ Áp Dc-dc 9v / 12v Xuống 5v 8a 3 Cổng Usb

Description:
-The module has two USB charging interfaces and one USB charging interface without protocol. Output maximum current 4A, with over-current protection function.
-USB protocol charging interface can automatically identify the type of charging device, and shake hands with the device through the corresponding USB charging protocol, so as to obtain the maximum charging current and save charging time on the premise of protecting the charging device. It can charge most mobile phones in for Apple, for Samsung and other markets.

Specification:
Input voltage: DC 5.6-14V
Output voltage: DC 4.8-5.6V adjustable, default 5V
Maximum output current: 4A
Output overcurrent protection: when the output current is detected to be greater than 4A, stop the output immediately
Input overcurrent protection: if the input current is greater than 2A, stop the output immediately
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: 39 * 38 * 16mm/1.53*1.49*0.62''

Operation Description:
-There are three USB interfaces on the module. The identification "Auto 2.4W" indicates that the USB port automatically recognizes the type of charging device, and "noIC" indicates that the USB port does not recognize the charging device. Devices that require a protocol to charge, such as for iPhone, can only be charged at the "Auto 2.4W" USB port.
-The input voltage range of the module is within DC 5.6-14V, and the maximum output current is 4A. If it exceeds 4A, the module will automatically shut down the output. In order to protect the rear module, the input terminal has a 2A self recovery fuse. When the input current exceeds 2A, the fuse becomes high resistance and the output is closed. Therefore, if the output current is relatively large, the input voltage should be appropriately increased and the input current 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. The adjustable range may be different for different input voltage.

Note:
Please allow 1-3mm differs due to manual measurement.
