An EL wire consume ~10mA/m, and need a 1800Hz, close to main voltage, sinusoid supply. (The noise is not a matter as the EL wire itself will cut off the frequency >2kHz).
for an installation I would like to power 1km of wire. Therefore I would need a 10A supply to power in order to do that.
What is the simpliest way to do such high-power sinusoid power supply ? I thought of :
- amplifying a low-power sinusoid signal.
- using a H bridge controlled in a way it will get a noisy sinusoid.
I'm trying to see if it is easy to do, or if it would be cheaper to just buy a bunch of 5 to 10 meter EL wire driver...
