DC 12V 8A Dual-Sources Automatic Transfer UPS Switch Battery Power Supply Module
Item Details
DC 12V Dual Power Supply Automatic Transfer
UPS Switches Controller Module Max 8A
Description:
It is used for two-way 12V power supply intelligent switching near ideal diode function. This enables efficient "combining" operation of multiple power supplies designed to extend battery life and reduce self-heating. When turned on, the voltage drop across the MOSFET is typically 20mV. For applications that use a wall adapter or battery, the second way is automatically turned off when the first access voltage is greater than the set point. (It can be used as a two-way battery to supply power to the load for intelligent switching. For example, the first battery is preferentially powered. When the first battery is dead, it automatically switches to the second circuit.)
Parameters:
Working Voltage: DC 6V-15V (default 12V power supply)
Maximum Current: 8A
Wiring Method: bonding pad
Size: 41mm x 43mm
Status Indicator: red, green
The first way is the primary power source, and the second way is the auxiliary power source. The second way must have power supply.
Default, when the voltage of the first channel is lower than 9V, the first power supply is turned off immediately, and the second power supply is switched.
When the voltage of the first channel is higher than 11.5V, it is switched to the first power supply gain, and the second power supply is turned off.
Packing List:
1pcs x DC 12V Power Supply Automatic Switching Module
