OFF/ON: Control the output state
 
Features:
 
Input and output voltage can display alternately.
The starting state can be set freely.
This module has the function of controlling 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 circuit case of connecting reversely. Working state instruction.
 
Input voltage mode:Boot default display the Input voltage mode、 show **.*、 the LED indicator light on and output state shut down.


Output voltage mode: Press S1、 the module switch to output voltage mode. show **.**、 the LED indicator light off.
 

If the output state shut down、 it show "OFF".
 

Alternating mode:Press button again input/output voltage alternately display (3s). Press button again、 switch to input voltage display.  

Memory mode:

keeping press S1 more than 2s、 the current mode is to memory for default boot state.

[0] Represent the default boot show input voltage


[1] Represents the default boot show output voltage


[2] Represents the default boot show alternately input or output voltage
