We manufacture products that run off 24VAC for residential use. We supply transformers for some products but not on all. We have issues sometimes with voltage fluctuations damaging our products, so my question is - is there an economical way to stabilize incoming voltage where I see the secondary of the transformers sometimes reaching 32VAC to closer to constant 24VAC?

 

Is the end circuit device an AC operated device or DC?
Max.

AC at 2.5A

 

If economy is an issue it could be tricky, what is the nature of the device?
It is unusual for an AC device to be sensitive to a little over voltage, particularly if it involves inductive devices.

LED operation and ionizers.

 

You could use a pure-sine-wave inverter to get a stabilised output, but I don't know if you'd consider that 'economical'.

Use a ferroresonant transformer (also known as constant voltage transformer or CVT). The efficiency of such transformers is about 90% provided the load is in excess of 80% of full load.

LED operation and ionizers.

Both the above will usually work on DC internally.
What part of the circuits are failing? It may be easier to modify the loads to survive higher voltage input.
Can you post circuts of the LEDs and the Ionizer?

I'd be using DC
Relay's motors 24 volt AC is good but LED's and stuff that using dc I make it happen with 24 volt DC

Regulating AC would be more complicated than modifying your devices to operate on DC.

 

Depending on your circuitry, you may be able to get by with ensuring the capacitors have a higher voltage rating, and the internal voltage regulators do to. For example, in some of the industrial control stuff I make, the regulators have a 72V max input voltage.
