Hi, my question refers to Allo’s Capacitance Multiplier:
It is said that one can adjust the dropout voltage between 0 - 3V. But however, I cannot find any information about how to do this. I also asked Allo direct, but didn’t got an answer until now. Therefore, is there anyone who can support for this?
Regards Axel
Hi. i have the CM. i did not change the adjustement of the trim poti.
standard is 0,5V
allo.com/sparky/capacitance … html#specs
my understanding is , here you can adjust 0-3V . So if input is 30V and you adjust to 3V dropout, 27V should be the output.
normaly ripple / noise is under 0,5V so standard should be fine.
so a Voltmeter seemed can be used to adjust. (input/output voltage)
Thx Judydudi,
my point is that I do not know how to do this. I guess the potentiometer is the little blue thing and to adjust it I need to turn the screw on it.
I’ve measured already the voltage before and after the CM, but there is no voltage drop. It’s the same before and after, about 7 V on both sides. Perhaps this is because I’ve measured without load (?).
Now I’m wondering about the spec. According to your link the min voltage is 10V. In the Volumino shop on the other hand it is written Max / Min 30V IN / MIN 6V IN and I like to use it for my power supply for the Raspberry (there it is mentioned “Suitable to feed clean power to your SBCs”).
However, with CM my Raspberry goes in to boot loops and it seems the power is not sufficient
