This one is for me to get my head around the various options and configurations of the V6 for my particular application.
Which is to power an old Trident console, and replace the old linear hand built PS.
My desired outcome is to have all three DC outputs bonded (AKA 3 channels of + and 3 channels of -) to giving me good old +16 0 -16 Vdc at around 4.5A
I am hoping this post will help others get a better understaning of what wires, resistors and jumpers to put where.
Below i attach a picture where i'm aiming to name and define PIN's / PCB pads so we all have a common "naming convention" when we are referring to joining this to that - so in reference to taht picture here are my questions to the forum - lengthy - yes, apologies in advance
First design rule (Thanks Joe), AC voltage in will roughly give you the same DC out. Meaning if you want 16Vdc out, use a mains transformer that has 16~18Vac taps (so in my case i need a transformer with 2 x 16Vac windings)
PS OUTPUT HEADER:
Although technically not a header, can someone please steal my drawing and draw in the "Channel Bonding" resistors and values required to bond the 3+ DC and 3- DC channels?
Or at least describe to me using the pin numbers where i put resistors and between what pin numbers do they go?
(would be cool if someone could describe both a 2 output bond option and a 3 output bond option)
This appers to be a JUMPER setup? where you can switch (configure) the +V3 DC output PAD to be EITHER a 48Vdc channel OR another + channel of the main DC supply (meaining with the jumper in the +V3 position, it will give you the same output a +V1 and +V2 - is this correct?
Looking at my diagram,
what pins do we join to achieve +48V
What pins do we join to achieve +V3
Again technically not a header
, but clarity on jumper positions required please.
What pins need to be joined for DOUBLER mode?
What pins need to be joined for TRIPLER mode?
Another poster asked about the Chassis earth vs. Audio earth (or 0V)
Please confirm for the forum that the pad marked CASE means this is how you wire/tie the PCB to the steel chassis of the box you intend to house the powersupply in, and that this is NOT the star earth or (0V) used to power your audio gear.?
Although covered in another post, keeping this info in one thread it's worth clarifying for the forum if the 0V pads on the PCB are joined on the PCB or are infact seperate, and WHY are they seperate.
Some PS builders might join the centre tap wires together at the transformer (to make a 0V across the 2 secondaries) leaving only 1 centre tap wire and might terminate that wire to only 1 of the 0V PCB pads.
(If you look at the JLM Schematic, it does imply it's OK to join the wires at the trafo and use only 1 of the 0V pads on the PCB.
Hope this info helps builders and for JLM to sell more these
