Rectangle resistors I believe is the old symbol, Er then again :scratch: Never really thought about it.. Try here, I used a polarized cap btw...http://library.thinkquest.org/10784/circuit_symbols.html |
| Brass_Machine:
Ok... so Darren... I need a PS that can do up to 42v and 3.0 Amps Maximum per Phase. What do I have to do different to pull this off? Looking at the pictures of other PS for this they have a BIG cap. What do you think? Eric |
| Bernd:
Eric, The important thing is what the transformer puts out and what the rectifier is rated at. A big cap like that is for smoothing out the AC ripple on the DC voltage. A transformer of 50volts and maybe 5 amps would be needed. The rectifier could be a 100volt and a higher rating than 5 amps. I'll check out what size those rectifiers come at. Probably can get one at the Rat Schack (Radio Shack) gotta go be back later with an answer I hope. Bernd |

I might have overloaded this topic already !!! :ddb: :ddb: :ddb: --- End quote --- Darren ................... I think half the civilised world is interested, I for sure am anyway ........... "Overload" .......... got to be honest and say ........ yes I'm struggling a bit, I've never really done much witrh electronics though I'd like to.......... I regognise a lot of what you describe and am conversant with a soldering Iron, my LandRover sports more lights relays and switches than you can usefully shake a stick at :poke: ............. together with an odd Zenner or two so I can flash 8 lights at once but switch them in pairs ........... but ............... could I ask for a simple wiring diagram to help me along a little ......... old fashioned I know ......... but wth :med: take care, great thread :bow: CC |
| Darren:
CC Steve?, No need for the :bow:, my knowledge of electronics is very limited, I only know how to build these things cos I have needed them in the past for my valve amplifiers. Get much further out of this narrow field and I'm truly sunk :thumbup: In fact I have no doubt someone here could make suggestions for improvements. If that is you then please speak up !! |
