Good speaker protection module
The module in general is OK, it does it's job as advertised.
However:
- make absolutely sure that the connected AC supply, when rectified and filtered provides at least 12V DC, otherwise the relays won't click. I've used a 9V AC transformer, and it was not sufficient.
- I had changed the filtering capacitor to a 25V unit. The provided 16V cap was very much on the edge from my point of view, and it would not live for very much long time, if run at the limit.

Mauvaise qualité
Certains composants sont trop juste !
Il faudrait plutôt l'alimenter en 10v. Le pont à diodes a brûlé avec les variations de courant ! Pourtant ce n'est pas un composant cher il en existe de même taille pour quelques centimes qui supportent plusieurs centaines de volts !
Les connecteurs sont de mauvaise qualité le plastique est trop souple.
Bref à éviter !

Works, but not perfect
It works also with DC 14V. The delay should be adjustable between 2-8s. I could not find any changes in the delay time while adjusting. It stays around 1-2s delay.
The protection needs 3V at the input to go into protection mode. If the voltage at the input is gone, it does not stay in protection mode.
I checked this protection against a cheap china protection (with LM7812) and found out, that the cheap does a better job. Protection already at 1.5V and stays in protection mode if the voltage at the input is removed. This is a far better behavior, because if it goes into protection mode, then there is something seriously wrong.
I also do not like the 3 pin speaker terminals. 4 pin terminal would be better.
Based on this i do not recommend this expensive protection board. It works, but there are better choices.

moyen
alors voila, je pense que ç'est de ma faute mais le module a griller .sur le descriptif il est ecrit/tension d'alimentation de 12 a 20 volt alternatif, donc j'ai injecter du 14 volt alternatif, bon c'est vrai que j'avais un doute en voyant la tension maxi des condensateurs a 16 volt .et forcement, 14 volt redresser ça fait pas 12 volt continu.enfin bref attention a l alim :12 volt continu et c'est tout!
