- LED lightbulb dimmer from ATX PC power supply parts ( transistor with heatsink and rectifier ). Dimmer is a linear type - for larger powers ( 100W classic bulbs ) need 20cm2 heatsink.
Circuit works with 110...230V AC 50/60Hz or DC
With trim pot. ( R3 ) can set LED bulb turn off point.
Well done, very interesting! Thanks for the schematic. 13 feb. 2024.
Очень хорошо 👍
❤❤❤👍👍🥰
So essentially you're putting a current limiter in series with the load... And the rectifier means the limiter always has the right polarity applied to it? Smart 🤓
Rectifier for transistor and all circuit like electronic reostat.
Transistor don't work in AC circuits.
Для регулировки мощности паяльника подойдёт эта схема?
Можно использовать для паяльника ( схема работает до 100Вт - только с радиатор 20см2 )
