Battery High Low Voltage Cutoff Circuit. Q1 inverts this action so that the on state is high. I found all your circuit and projects interesting but please i need a special assistance. Only you have to change the 5 1v zener diode value according to the battery voltage type.
By proper choice of r1 and r2 this circuit will work well for shut off voltages in the range of about 4 5 to 10 v. So it helps to protect the circuit damage by the high voltage.
As explained above the transistors sense the presence of the dangerous voltage levels respectively and activate.
High voltage cut off op amp here the op amp is used as a inverted amplifier. Hello swagatam thank you for the 48v solar battery charger circuit with high low cut off and i am going to try it out. Q1 inverts this action so that the on state is high. I want to build a low and high battery full cutoff that can handle about 360vdc 30 batteries in series such that when battery is full at 405vdc charging voltage will cutoff and when battery drop to like 325vdc it also cutoff battery low.
