do u guys know where to get auto current cut off device????
try to find in pasar road liaw but did't find it.

this device is ued as this way.....
the input of the amp is radom,sometimes very high and sometimes very low.

then i have an electronic robot which only work properly in certain amp and above.let say 3amp and above this robot will work fine.

so now i would like to conect an auto current cut off thing in btw the inout and the robot.when the input is lower than 3 amp then automatically the current will be cuted off.only when the current is higher than 3amp, then the currentwill conected back to the robot.

can u guys suggest any other plcae like pasar road.

Electronic Robot? One part of the car? Or FYP? haha.... :shades_smile:

I think u put in wrong forum...

Devices u mention hard to get in normal electronic shop....

But u can diy it.....

I think 1 low resistance resistor, 1 comparator(op-amp circuit), and on/off devices(relay or transistor circuit).. can settle...

If you interest, i can send you schematic... :regular_smile:
