    Thank you so much I made the circuit and it is working for me perfectly well. Though I parallel two 5v zener diode to get 10v. It's wonderful. Keep it up. Once again thank you for the knowledge.

    I have seen similar zener based low voltage cutoff diagrams but they don't have the capacitors. What benefit do the capacitors add in this instance?
    I want to use it in my vehicle to keep the battery from going dead if I leave my lights on. Obviously I will need a higher amperage relay, are there other things I should consider?

      if you using 9V, cut off 9.5V. So we need 10V Zener. because battery dead damage voltage 10.5V

    How much watt it can handle??

    • @rustygear9370
      @rustygear9370 2 місяці тому

      The wattage est based on the relay you are using.
      The one in the video says 14 amps so 14 a x 12 v = 168 watts in DC mode
      If you plan to use more wattage, i.e. more powerful relay, be careful to the amps the relay uses to operate (The winding amps, not the contact ones) because it can burn the transistor.
