    12v Output
AI Thread Summary
Using a 12V transformer for a product requiring a 6V output is not advisable, as it can lead to excessive current and heat, potentially damaging the product or causing a fire. The increased voltage may alter the product's operating characteristics, risking further harm. Additionally, this practice could void any warranties associated with the product. While some users suggest it might not cause immediate issues, the risks outweigh the benefits. It is best to use the appropriate transformer to ensure safety and functionality.

Hi,

I have a product that needs a 6v transformer. However all I have is a 12v output transformer. Can I use this? and is it dangerous?

Thanks

Well, it won't hurt you. :smile:

:cry: But it will hurt the product! :cry:
 
Many thanks Tiny-tim.
I know that running a 6v output with a transformer meant to give out 12v is not ideal. But why is it not ideal - how does it hurt the product?

Hi fialor! :smile:

You haven't said what the product is.

But as a general rule:

i] It'll invalidate the warranty.
ii] It'll put double the current through every part of it, which may "burn something out", possibly beyond economic repair.
iii] ok, maybe it won't do any harm … but the only way to find out is to try it … and then it'll be too late! :smile:

It could be very dangerous.

As tiny-tim has said, using 12V instead of 6V, can result in excessive heat. This excessive heat could ruin a part, or, if large enough, even start a fire. Or the excess voltage could change the operating characteristics of your product. Or nothing extraordinary might happen.

I do not recommend this course of action unless you really know what your doing.
 
Thank you Tiny-tim and George Jones.
Information was really helpful.

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'
I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
