This circuit is over voltage protection board to disconnect the power supply to the application board when voltage over setting voltage.

This listing is for UN-assembled board, buyer has to soldering all components on the PCB board.

Technical information:
- Need Supply voltage 12VDC.
- Input range 5-15V DC ( Maximum of voltage should be not over 15VDC )
- 1 Relay 10A / Max : 250V AC
- Variable POT to adjust setting voltage from 5 - 15VDC.
- Comes with the instruction how to use in image. Easy to understand.

Example:
- Setting voltage at 10VDC, if some time voltage is 10.2VDC from DC power supply.
Relay on the board will disconnect the application from spike which occur every time in AC line pass through AC-DC transfer in Power supply.
