DIY an output adjustable vehicle power supply, connect the 12V input, and output could be 14-35V(adjustable freely), However, the output voltage can not be less than the input voltage.
Car laptop power supply: connected to 12V power supply, output voltage regulation as your notebook need.
Boost charger. You can use the 12V power supply to charge battery more than 12V, for example, 24V batter
5V Omron solid state relay 240V 2A, output with resistive fuse 240V 2A
Size: 24*32*21mm/0.94*1.25*0.82”
Input Power: 5V DC (160mA)
Input control signal voltage:
(0-2.5V state low relay OFF)
(3-5V state high relay ON)
Description
* on-board AMS1117-3.3 chip
* the input voltage range of 4.75V-12V
* on-board power indicator light, indicate power is turned
* board size: 18.5 (mm) x10.5 (mm)
Features:
* Dual measurement of AC voltage, AC current with AC current transformer
* Voltage Measuring Range: AC 80 ~ 300V
* Current Measuring Range: AC 0.1 ~ 100A (Current in excess of 1A is recommended)
* Display backgroud color & Type: Blue & LCD
Input and output voltage can display alternately
The starting state can be set freely.
This modlue has the function of controling the start-up and shutdown by the button. So it can control easily the state of output
This module have the big power MOS to protect the circuite in case of connecting reversely. This can improve the effiency and reliablity.
