Author Topic: power supply w/ no model number Jim Henk Master Film Handler Posts: 364 From: San Diego, CA Registered: Feb 2006 posted 12-19-2012 09:35 PM                     Howdy. I've got an LED power supply with just the title "Kelmar Digital/Analog Power Supply". Black metal case, no model number anywhere on it. Can anyone identify, and is there possibly a manual for this? BTW: pinouts on the back: (9 pins) Digital: LED Test + and -, (pins 1 and 2) LED + and - (pins 3 and 4) Analog: LED Test + and -, (pins 1 and 2) LED + and - (pins 3 and 4), Pre-amp + and -, (pins 5 & 6) and 2 Remote outs jumpered together (pins 8 and 9) What is LED Test? Why would an LED Power Supply have pre-amp connections? Curious minds would like to know...  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 12-19-2012 09:49 PM                     LED test is to allow a ampre meter to measure LED current The LED supply provides the power to the preamp on the reverse reader  |  IP: Logged Jonathan Wood Expert Film Handler Posts: 206 From: Oxfordshire, United kingdom Registered: Jan 2008 posted 12-19-2012 11:01 PM                     Sounds like the one I have with my century projector. Has a removeable 19inch face plate to allow it to be rack mounted?  |  IP: Logged Jim Henk Master Film Handler Posts: 364 From: San Diego, CA Registered: Feb 2006 posted 12-21-2012 01:57 AM                     Maybe, but I don't have the rack mount size plate. My unit is around 6"x9"x3" with small mounting wings that extend about 1/2" on two sides. Thanks Gordon for the info!  |  IP: Logged Jonathan Wood Expert Film Handler Posts: 206 From: Oxfordshire, United kingdom Registered: Jan 2008 posted 12-21-2012 12:39 PM                     Yep, it's the same one. Like Gordon said it provides power to the LED / pre - amp. Never come accross a manual for it tho?  |  IP: Logged Jim Henk Master Film Handler Posts: 364 From: San Diego, CA Registered: Feb 2006 posted 12-22-2012 05:12 PM                     Uh uh. Pretty straightforward though. Manual probably says "Plug in. Use only under adult supervision." (leaves me out...)  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 12-29-2012 11:26 PM                     I have the rack mount plate for that power supply Jim...remind me to give it to you next time we meet up.  |  IP: Logged
