How to connect a EURA AC-20C7 code lock to an electric door strike without a controller?

Question

Hello
I have a problem with a EURA AC-20C7 code lock after connecting it to an electric door opener it does not open. I have connected it according to the YouTube video titled: "Video instructions for connecting the AC-20C7 code lock with the WS-70H1 wifi controller I EURA tech. ( without connecting the controller, which I do not want) please help

What specifically do you have a problem with, because what you write about are generalities: with the power supply, with the control of the deadbolt with the correct power supply, or with something else?
Draw on the diagram from the manual what connections you have.

And in general you should connect the device according to the instructions and not according to some jutube videos, because they are crap...

Yes, there is a problem with the power supply to the deadbolt, as if there is not enough current going to it (unfortunately I do not know enough about electricity to explain this in any other way).

Because the deadbolt should be powered from a power supply with sufficient current capacity. As you have probably noticed yourself, there is only a relay in the keypad, which closes the circuit consisting of the power supply and the electric strike.
The power supply should have a current capacity of approximately 300 - 350mA. Unless you are using a common power supply for the keypad and the striker, then you need at least a half-ampere power supply.

Not enough. It should be 1A.

You are right. I forgot it was the electrical section....

This is no longer the electrical section .

It may be that no voltage is reaching the electric door opener at all. It is best to use a small 12V bulb for the duration of the test. When it lights up (at the right moment), it means that everything is connected correctly. Only then can you connect the electric door strike, and then it may also turn out that the power supply is not current-efficient.

Perhaps many things, so much so that until the author gives details we can guess long and passionately. .

It can still be called from the aforementioned section, so there it is. But Bronek is right. We don't know what kind of power supply the author has for this deadbolt (AC or DC and therefore what the current draw is) and what the deadbolt is in general, so it's always better to take an oversized power supply.

A diode is needed on the bolt to protect against against overvoltage.
