Sure. I just grabbed something in the std. LTSpice lib that had a piv of 600Vby the way...Why MUR460?
Won't a 1N4007 suffice?
The resistors dissipate ~1/2W each. A mini-transformer would dissipate >1W. A relay about 2W.Its a transformerless psu,!!
i would use a capacitor to drop the mains like the circuit in my pm, resistors get warm dropping too much voltage.
Raise R3 from 1K to 2.2K, and the peak current in the green LED and the opto input is still about 7mA@MikeML
How about this diagram. I plan to use standard 3mm green led on the PCB. Would the circuit suffice.
I do not use ur simulation software, but LT seems better. Can you simulate my circuit when you get the time.
I was going to as ask about that. For this circuit, it is a mistake, as was adding the 100uF across its output. All it does, is make a lot more heat in the series resistors...I see you opted for a full wave rectifier. I'm not fond of half waves either... it's part of my impractical, perfectionist side, I guess.
And add components... I hadn't thought about that... I just knew I was being impracticalAll it does, is make a lot more heat in the series resistors...
Questions:The 100uf helps to avoid short term power outages like glitches and also false triggering.
See post #53I do not like to feel them warm. Now cool to the touch.
