Cant figure out power connections on ptz

[Gunner 0]

hi everybody im new to the forum

i have recently bought a ptz and im just not sure about the three wire power plug on my camera. The middle wire is ground and the two outside wires are 24v ac. Do i need two 24v connections to these two wires or is it a positive and negative. i have bought a transformer to run the camera but it doesnt really tell me anything either, it has two wires blue and red and doesnt tell me if they are both positive or positive and negative.

Any help really appreciated

You only need to use the 24VAC connections. There is no "positive" and "negative" with AC.

Thanks soundy so all i need to do is put the two wires from my transformer into the two 24v connections on the camera? sorry for being so dumb but im not familiar with ac electricity or ptz,s

Assuming you've bought the correct transformer yes that should be all it takes.

 

An important consideration though, is the current capability of the transformer - if it's not sufficient, the camera could have issues powering off and on, and/or it could fry the transformer. The power rating should be listed on the transformer in "VA" - ie. 40VA, 75VA, etc. For a PTZ, you generally want AT LEAST a 40VA... ideally 75VA or better.

Hi soundy havent got it handy now to see what it says on it about va but its 2 amps or 2000ma if thats any good. The camera spec says

 

input voltage-18-30v

 

power-11watts

 

power on in-rush current=1.5amps

 

hope this helps, if not i will post the transformer info tomorrow morning

thanks again for all your help

Hi soundy just to update you its a 60va so it might just do it, thanks for heads up on that one as id never have known
