Automatic re-ignition of a converter

[izentrop]

One solution is to reverse the control of the relay by a transistor.

I'll see if we can't get there by changing the setting of the "triggers"

it reverses the direction of the current in the relay, not the direction of operation...
The relay should energize when the out output is deactivated.

The relay should energize when the out output is deactivated.

I rechecked, the operation cannot be changed:
The relay picks up while charging the battery and picks up when the end of charge detection is reached. Then reattaches only when the low battery threshold is reached. This is its normal operation.
The consumption of the bonded relay module is 25 mA measured. We have time to see coming with a 200 Ah battery.

I proposed this simple assembly if it can help, now everyone does what they like

My old outdated charger has found new life and can be used as a permanently plugged trickle charger.

The last diagram with changeover relay should work using the NO contact.
For the first assembly, it is necessary to invert the connections at the level of the contacts of the load relay.
Sorry for the errors and thanks DD for pointing them out.

You're welcome, I really like this kind of DIY

On your last diagram, by putting a PNP and a resistor next to the LED, it could work the other way around.

For the 24V models, they make some that range from 6 to 60V!.

Otherwise, for the initial subject, it would be necessary to see which regulator is used, for the characteristics of the consumer cut-off system.
(to control the decoupling relay)

I also like not too complicated crafts.
Yes, for the PNP, I went into the drawing without thinking too much.

To make diagrams I tried several software like fritzing or https://easyeda.com/editor#id=6484d278b ... 8559d66edf, but I always come back to photofiltre 7. The only drawback is that it is not easy to draw the threads.

Ah okay, the improbable value of the diode, the relay that could no longer close the flat battery, the reversal of the direction of the current in the relay, coughed coughed ...

"It's the circuit design app's fault"

I was also thinking

Thank you Obamot for your enlightened opinion
What software do you use to fix the schematics? I like Dia

It's vector drawing software, you can't insert images into it.
For this I have already written, I use the software light filter 7 Light and practical. The only problem is drawing the lines which is not as easy as in DIA for example.
Saving in gif format is convenient, you don't lose quality with each re-save and it's lighter than png, especially by limiting to 16 colors.

Oh damn you tricked me

None at the moment, but I had heard of Altair... (there must be others...)

it seems to me that he (or someone else) allows you to simulate your circuit ideas, to make a virtual power-up even before having purchased any component or physically finalized any circuit, and he will detect any shorting problem for you -juice and/or if a component is overheated... (With 'probable' thermography please)

Well, maybe it's not worth putting this in anyone's hands (me for example)
It would have been useful for my RIAA circuits... I could have dared to test variants.
Had to reduce the hiss to improve the Sn / noise ratio, and eliminate distortion in very low frequencies (on the 1st, 2nd, 3rd harmonics etc ... at 5Hz 10Hz, 20Hz 40Hz, 80Hz 160Hz and so on)

It reminds me how much the world has changed, the hobby electronics journals of the time (not really for beginners), who deliberately slipped a gross error into the circuits they published, so that their little secrets "remain among professional people"...

Well yes, all you have to do is drag and drop.
Like this, quickly...
