hello,
I am new to this forum. And i know nothing about electronics. But i have a friend who knows about electronics but doesn't know good english .
The problem is with a halogen power source (12vac 100W) dimmable. It is a transformer based system to convert (230v). The problem is when the mains shoots up to 260v+ , the output is 13+. When the power is in the range of 220 to 240 , the output is 11.8vac to 12.1vac.
The dimmer used is a fan dimmer. The output ranges from 3.5vac to 12vac in normal condition.
Is there a circuit to regulate the output to under 12 when there is a increase in mains (260+). Like the output must never exceed 12vac, but must be dimmable ?
Any links , circuit schematics, Ideas are welcome.
Thanx in advance
