Hi Guys.
This is my first post, new to the forum but would like some help with regards Relays.
I have not worked with relays before and just need a bit of guidance.
I have a Unifi UA-HUB that should power a 12v strike lock to open when needed but the 12v that is given out does not have enough amps for this to properly open the lock. The max rated 12v output from the UA-HUB is 12v 1amp.
I am looking to use a relay for this and an external 12v 3amp power supply but not to sure how this would wire up or what relay I would need. I have had a look on Amazon and eBay for some and there are loads out there but just need a hand choosing the right one.
So my question is this: - I am looking for a relay that will activate while receiving a 12v signal but will supply power from an external 12v source. When the 12v signal ceases, the relay will close
Can anyone help me with what I would need to buy and if possible, a wiring diagram how to wire this.
Thanks in advance.
Hal
