once again, thank you all very much for kind support (especially calculations).
I agree..will need to experiment with capacitors.
May I please ask three more questions:
- where to place currency limiter resistor (in front of step-up converter, or after converter)?
- If I place it as resistor R2 on attached picture, (after converter), it will slow down charging of capacitor? View attachment 104942
- Should I charge capacitor to higher voltage and to use step-down converter for the solenoid? View attachment 104943
Thank you,
Alan
