Heating and air conditioning controls run on 24VAC. There are tons of them available.maimonides said:On the other hand, 12V tranformers may be more easily available than 24V.
0xDEADBEEF said:It depends on the load, but the cheapest and least power hungry option to get low voltage AC from higher voltage is sometimes a series capacitor. I have seen this trick with some indicator light, I think it was a diode.
maimonides said:"Transformator" is german for transformer; and Germany is nearer to Eastern Europe than GB or USA, so that´s that.
@track: you might tell us which application really needs 24V AC. Maybe somebody can suggest a workaround.
On the other hand, 12V tranformers may be more easily available than 24V. Take two 12V transformers and put the secondaries in series. (take care of the phase, or you´ll get 0V). You´ll find 12V transformers in halogen lamps resp. their mains adapters, in wallwarts, mains adapters, battery chargers, doorbell transfomers or ...
Find something you can cannibalize. Even in Eastern Europe, people throw away things which still have working parts inside.
Good luck with your project
track said:Thank you maimonides. My friend works on ocean and he asked me for advice. He said there is no more transformers around to use. I don't know anaything about device but I think it's not some huge load. I told him about resistor and to be extremely careful. He did it on test board and it works for now. Told him about possible heating and safety too. Here, on forum, I just wanted to ask is there any other option. Thanks everyone.
quit complaining. Several languages call the transformer "transformator".Averagesupernova said:When one refers to a transformer as a transformator, it would be best to just lock the thread. I mean seriously, what level of experience does this show?

Unless there's something not being communicated well about the needs, that's not true. There are tons of 220V to 24V transformers out there: http://www.google.com/search?source...gc.r_pw.&fp=26e21bc21c823d34&biw=1136&bih=806track said:Thank you maimonides.

I strenuously agree!AlephZero said:Given the low level of knowledge that OP seems to have, IMO the only safe options are a transformer or a complete "ready built" power supply.
The purpose of reducing 220V AC to 24V AC without a transformer is to convert high voltage alternating current (AC) into lower voltage AC that can be used for various electronic devices. This is necessary to protect the devices from damage and to regulate their power consumption.
No, using a resistor to reduce voltage is not recommended. Resistors are designed to limit the flow of current, not to reduce voltage. Using a resistor to reduce voltage can cause overheating and damage to the electronic devices.
Reducing voltage without a transformer can pose several risks, such as damaging the electronic devices, causing electrical shock, and creating fire hazards. It is important to use proper equipment and techniques when reducing voltage to ensure safety and prevent damage.
The process of reducing voltage without a transformer involves using a voltage divider circuit. This circuit consists of resistors that divide the voltage proportionally and provide the desired output voltage. However, this method is not as efficient as using a transformer and can cause power losses.
No, not all electronic devices can be powered by reduced voltage without a transformer. Some devices require a specific input voltage and using a voltage divider circuit may not provide the correct voltage. It is important to consult the device's specifications before attempting to reduce voltage without a transformer.
