5A Eurorack Power Supply and Panel Power Entry Assembly Instructions
!!PLEASE MAKE SURE YOU FOLLOW THESE INSTRUCTIONS WELL AS ERRORS CAN RESULT IN A DAMAGED POWER SUPPLY OR MODULES!!
Noting could be more exciting than finally getting a great power supply into your rig and these instructions are here to help you assemble this simple kit asap. Below you will see a photo of the 3U Panel with Panel Controller PCB, 3U Panel, and Main Power Supply PCB. Below that is the same, but in 1U @ 6HP.
If selected, your kit will include a TDK 250mA 12v regulator in place of the 1.3A Murata regulator shown above:
After you determine which kit you bought, check to make sure you have all of your parts, then grab the main power PCB and populate the PCB as shown below. Start with Resistors, 3mm LED’s (the FLAT side of the Silk Screen on the LED area indicates the NEGATIVE or CATHODE or SHORTER lead of the LED), Diodes and Power Cable Connectors.
After that, add the 16-Pin Keyed Connectors, make sure you orient them as below. The KEY on the Shrouded Header will correspond with some small notches on the Silk Screen. Solder each pin from the backside of the board very carefully as to not accidentally connect two or more pins together with too much solder.
Next, Add the two power IC’s. The larger will only fit in one way, the Smaller COULD be inserted backwards; follow the orientation below.
Fantasic, pretty simple, huh? Check your work against the photo below to ensure proper orientation of components.
You are now ready to start assembling your respective panel.
TDK 250mA users: use the photo below for reference orientation. The 5V converter (U2, not shown) is optional and orientation is identical to the standard 1.5A version if installed.
Please follow the instructions below for how to assemble your 1U or 3U Power Entry Panel. Both the 1U and 3U have very similar instruction.
1. Seat 2.2K resistor onto the PCB and solder into place.
2. Strip a small a short amount of BOTH the RED and BLACK wire AFTER you have cut the wire to your desired length and then tin both ends with a small amount of solder.
Kit Comes with 2 FEET of each Red and Black wire. If you need more, you can purchase some in our store, or find any 16 gauge AWG type wire.
3. Run the red wire trough the back of the PCB going in through the + (positive) side on the front. Run the black wire through the back of the PCB going in through the – (negative) side on the front. Solder both wires into place and trim excess wire that pokes through the front.
4. Take the top nut, locked washer, and keyed washer off of the SPST or SPDT (either will work) switch. You will not use the locked washer or keyed washer, so you can put those aside. Run the bottom nut up one thread so it sits barely off the bottom. Next, take the switch and mount it to the Panel and screw down the nut finder tight.
5. Take the top nut and washer off the DC jack, and seat into the front PANEL. You will not need the washer, so toss that aside as well. Then mount the washer into it’s panel hole and tighten the nut down finger tight.
6. Take the LED and sit the shortest leg through the LED hole that’s closest to the flat part of the LED circle on the PCB.
DON NOT SOLDER THE DC-JACK, LED, OR SWITCH to the PCB board YET. First align all of your components together to make sure a nice level fit. THEN solder the LED in place after you have make sure that the 5mm LED has slide into and has stopped fully into the Front Panel. Once you have a good fit of the other components, solder those as well.
Clip your excess wire and leads, tighten your nuts (not too hard) and you are ready to wire this up to your Main Power Supply Module.
Connect your color coded wires to their respective input connectors on the Main Power PCB and screw them down tightly.
You are now ready to plug in the 12V 5A Power Adapter into the front panel. Check to see if your panel LED illuminates and that the 3 LED’s on the Main Power PCB illuminate as well.
You can now connect your Power Distro PCB’s or Flying BUS Cables, now add your modules and make some noise!
