content: I got one of these supplies from KJDS on Ebay. When it arrived ( very well packed and quick delivery) i tested it and all was well with it.Except...The Voltage meter readings are very slightly out, Current was perfect! But me being me, wanted to adjust this. So had i quick blind play with the pots inside and could not manage to change the Voltage readings, only the current.So the search for the service manual started. Anyway after a long hard search for "TS series service manual" i gave up the search. Later i thought i would have a look on the net for other service manuals for supplies that might be similar and found the "TTi 'S' series service manual". This turned out to be the manual for the actual power supply i have.WTF ?? Why don't they name these things properly!So for anyone looking for this service manual it ishereto save you the pain i went through.Enjoy.

content: I found a copy elsewhere after much much searching. I did save the pdf but foolishly didn't bookmark the link so thanks for sharing that one.

content: I also got one, and powered on quickly but didn't test voltage accuracy yet. Love the lack of fans, current adj knobs are bit coarse and maybe I'll replace those 2 pots.I need to replace the plug with a schuko, since the adapter I have (for a battery charger) doesn't have ground connection, and I don't find that safe for lab use.Kjds, I sent a message on eBay: did u get it? I'll check the manual now, which should give me the answer about protection with a non fused plug.

content: Plug changed and voltage measured. It's quite accurate for both outputs, about 1% higher than displayed. I'm not using any load (I don't have one nor plan to buy one). I'll check the schematic with a friend and decide if I want to attempt to calibrate or just set a little lower voltage to get it rightDid I say that I love the lack of fans?

content: Quote from: Telstar on March 10, 2013, 10:14:52 amThe service manual linked above describes how to tweak the pots to get the calibration spot on. It's the first couple of pages of the calibration section.

content: Quote from: Telstar on March 10, 2013, 10:14:52 amI suppose you have conected the sense wires (or bridges) ??It seems like (photo) the sense bridges are included.I bought a used PL310 that were slightly off , but seller had "lost" the bridges and prob didn't know what they were used for.After installing a couple of wires , it was doing quite nicely./Bingo

content: Quote from: bingo600 on March 10, 2013, 12:36:06 pmThere are no fans in the PL330DP. I've still got a couple of DPs left should anyone want, but once they've gone I suspect I won't get any more.

content: Quote from: bingo600 on March 10, 2013, 12:43:13 pmYes, and they were included.I will eventually calibrate it later but for my current needs (10 to 20V @2A) actual values are perfectly fine.

content: I think that one might be in the "TTi don't give service information out any more other than a few sheets of basic info" territory. Still trying to screw a proper service manual out of them for my TF930.If you phone them up and ask or send them an email they usually send service manual out if they issue one.
