Customer:
I need a step-up module that takes 12V input and outputs 24V. The input must not go below 12V.
Trebao bi step up modul koji je ulazni 12V i da izlazi na 24V.
Ne smije biti niži od 12V ulaz.

We have the following step-up modules available:
Customer:
I think the second one is what I need, but I want to verify before ordering.
The situation is: I have a terminal that continuously outputs 10.5V. Only when it sends a signal do I want to boost it to 12.5V, but the gate operates at 24V.
My question is: how do I configure this so that when we boost the voltage, it will then release the switch to close the gate? In other words, I only want the step-up to activate when voltage jumps to 12V.
Mislim da bi meni trebao ovaj drugi ali htio bi provjeriti prije nego narucim.

radi se o terminalu koji non stop pušta napon 10.5V samo kada šalje signal automatskim vratim je 12.5V ali vrata rade na 24V.
Moje pitanje je na koji način ako s ovim povećamo kako će poslije otpustit sklopku da se vrata zatvore. Znači samo kad skoči na 12V da napravi step up.
Hvala na odgovoru.

Soldered Support:
You will need some logic circuitry before the boost terminal that provides different logic signals for different voltages and thereby switches the boost on/off, which will then of course open and close the gate at 24V.
You can do this for example with an LM393 voltage comparator and one MOSFET transistor. There are certainly other ways, this is just the first that comes to mind.
trebat ćete nekakvu logičku elektroniku prije boost terminala koja će davati različite logičke signale za različite napone i tako paliti/gasiti boost, koji će onda naravno otvarati i zatvarati vrata na 24V.
To možete napraviti recimo s LM393 komparatorom napona i jednim MOSFET tranzistorom. Sigurno ima još načina, ovo je prvi koji mi pada napamet..
