Thanks Dave, the Led I had bought for this is rated for regular 110 volt AC. I figured it would glow at least a little with the 55 volts DC. It worked fine straight of a 110 wall outlet. But I could not get it to work at all with the Powersupply.
I did not know they only work in one direction maybe I try this again. Would I need a resistor for this? --- In [EMAIL PROTECTED], "Dave Fisher" <[EMAIL PROTECTED]> wrote: > > 2 lamps in series would be fine - but when 1 blows / dies both will go out ! > > LED's work fine with DC - BUT you do need a series resistor to limit the > current to about 10/15 milli Amp > - a good rule is about 820 Ohms for 12 Volts - So for 55 Volts 3,200 Ohms > should do the trick. > > Remember that LEDS are like diodes - they only work one way round on DC, so > if > it don't work this time - turn the LED connections arround. > > One more thing - If you have BIG caps in your power supply the LED could > well > stay on for a LONG time after you ditch the power ! > > Rgds > > Dave Fisher UK > > > -----Original Message----- > From: Torsten [mailto:[EMAIL PROTECTED] > Sent: 25 October 2004 18:17 > To: [EMAIL PROTECTED] > Subject: [CAD_CAM_EDM_DRO] Two Lamps? > > > > > Got a question, I have a Powersupply > delivering 55 volts DC in my driverbox > connected to a Caps to store and smuth > out the current having been zapped a few > times I would like to hook up a little > light bulb to drain out the current after > it is shut off. > Would also be nice for the visual feedback > to see when the thing is charged. > > On the first attempt I learned that a Led dose > not work with DC current. > > So now I am Looking at some Bulbs with a filament. > What I found is a "Miniature Bayonet base Lamp" > rated for 28 volt .040 amps I belive I should be > able to wire two of them in serial to make it work > on my 55 volt system. > > Will this work? > Any thoughts, please share. > > > > > > > > Addresses: > FAQ: http://www.ktmarketing.com/faq.html > FILES: http://groups.yahoo.com/group/CAD_CAM_EDM_DRO/files/ > Post Messages: [EMAIL PROTECTED] > > Subscribe: [EMAIL PROTECTED] > Unsubscribe: [EMAIL PROTECTED] > List owner: [EMAIL PROTECTED], [EMAIL PROTECTED], > [EMAIL PROTECTED] > Moderator: [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] > [Moderators] > URL to this group: http://groups.yahoo.com/group/CAD_CAM_EDM_DRO > > OFF Topic POSTS: General Machining > If you wish to post on unlimited OT subjects goto: > aol://5863:126/rec.crafts.metalworking or go thru Google.com to reach it if > you have trouble. > http://www.metalworking.com/news_servers.html > > http://groups.yahoo.com/group/jobshophomeshop I consider this to be a > sister site to the CCED group, as many of the same members are there, for OT > subjects, that are not allowed on the CCED list. > > NOTICE: ALL POSTINGS TO THIS GROUP BECOME PUBLIC DOMAIN BY POSTING THEM. > DON'T POST IF YOU CAN NOT ACCEPT THIS.....NO EXCEPTIONS........ > bill > List Mom > List Owner > > > Yahoo!
