thanks, im starting to learn new things today....im getting the power concept at half cycle.
im going to dig out a few diodes and do a quick test tomorrow
forgive me if im wrong, but wont the diode still pass 120 vac but at a half wave cycle?
if so, im concerned its still too high a voltage even though half the time?
yes, just popped up...i like the simplicity...can you suggest a equivalent diode in a package other the surface mount? stud case?
I suppose I would need to actually set it up to test for flicker, but im thinking it may not be apparent as those mid to high wattage projection lamps take a couple...
Hello Brian, i want to be sure i have the correct understanding of your said use of the capacitor....is it used for filter a triac dimmer rf, or does is reduce the voltage when in series with the lamp?
if i use a 10.2 ohm resistor, what wattage rating do i need?
i figured two separate supply...
autotransformer was my first idea, however, i could not find anything close other than my bench unit which i tested with the lamp, not to mention the cost of the transformer i did see were over $75 each. Cost prohibitive. I need something I can build cheap as there will be aprox 8 lamps I need...
Hello Folks, here's a unique challenge I dealing with.....
Please bear with my lack of knowledge.
I'm trying to find a way to power a 82 vac, 300 watt project lamp from 120 vac.
The lamp/lens assembly is salvaged from an old Kodak slide projector. The lamp power was obtained from a fan motor...
