Does anyone know of a 12VDC/24VDC to 12VAC inverter? I have a piece of equipment that will work with 14 to 24 VAC @ 1.5 Amp or 12 to 35 VDC @ 1.5 Amp. But I am tying in a light bar that will only take 12VAC. I only have a pair of wires to work with so two sources of power is out of the questions.
Any help?
It's called an inverter with a transformer plugged into it. Get a small 12VDC to 120VAC inverter then plug a wall wart transformer into a receptacle on it to get you your 12VAC.

Space is at a premium I do not think I can fit any of the inverters I have seen inside the call box. The size I was looking for was like this, but to 12VDC:

You can order a camera power supply that will convert 120VAC to 24VAC.
Look at the Video Alarm PS24

That's just a transformer.

I suppose it would help if we know what you were doing. I had no idea that space is a premium for instance. It also seems like you are going through a lot of trouble just to power a light. What kind of light bar is it?

Have you tried a standard 16vac transformer like the ones used for security systems?
Edit: Sorry, I misread the specs. The transformer may blow the light up if it can only take 12 volts dc.
Since both can operate on AC, then wouldn't it be easier to send 24VAC down the wire and use a small transformer to convert 24VAC to 12VAC?
Buzzzzzz. No, sorry Rob, the "piece of equipment" operates on DC.
So here we are at the end of round one. Score is Tec Talk 0 and OP 0.
You are driving us nuts with this DC/AC thing. Even you can't keep it straight. :bang:
Get a light that operates on DC. Plenty of them out there.

If you have 12v DC present, like Hal suggests, use a 12V DC light. ANY auto parts store will have SOMETHING you can use, even if it is just sacrificial to change your light bar to 12V DC.
My grampa changed his boat wiring from 6V to 12V and reused many of his light fixtures, some, just by changing the lamp socket inside the light fixture's housing.
It is a lot easier to convert AC to DC via a simple rectifier circuit, but the best you can get from the DC to AC conversion is square wave AC anyway, not true Alternating Current.

You can get true sinewave A.C., but it usually comes rather more expensive for any given power.

He says the equipment will work with 14-24 VAC
OR 12-35 VDC.
That's why I thought, "why mess around with the DC at all?"
