Happy New Year!
I like Accopian! They are not the cheapest by any means but they are reliable!acopian.com
Yeah I'll probably end up going with acopian. I guess I'm more concerned about the amperage/current rating. I'm guessing the components/DOA's themselves will draw around 2-3 amps (around 120ma max each) and I should reserve another 1 or 2 amps for "headroom".
JH990=25MA so that means you can power approx. 70 of them give or take with a 1.8A supply!
Yes you are correct I looked at the DS to quickly. But that is maximum I agree with the other post no need to go for broke! Now that I am thinking more clearly will you be using other opamps for output and eq etc...?So that means with your 1.8A supply you can do like 16.
Check my floorbox power supplies.https://groupdiy.com/index.php?topic=52462.0FB1 output is rated at 1.9A but the transformer is actually 150VA. Take away around 12VA for the phantom. That leaves you just under 70VA per rail. I bet it will do you fine. But if you would like to have a bit more I also have a 216VA version of the transformer. The case also accepts a second dual output regulator. This can power your lights and other things.The main dual rail regulators are LM 338 and the board is designed to provide 5A. There is a provision for an external heatsink for high current output.The power supply has its own mains switch, integrated with the IEC but I have recently designed an optional relay card for remotely turning the outputs on/off. The picture of a five output version with the remote relay board is attached. +48V board is placed under the relay board. We can customise to any version you need.Assembly manualhttp://www.robotica.co.uk/tac/FB_PSU_ASSEMBLY_MANUAL.pdf
I thought the assembly manual would clarify it but I'll explain further.I realise that you need + - 24V.The transformer has 4 sets of identical 0 - 17.5V - 25.5V secondaries for the main rails and one 0 - 48V secondary for + 48V.For 16V you use 17.5V tap and for 24V you use 25.5V tap.On 216VA transformer 24VA is allocated to +48V (500mA) which is normally way more than what you need but it is there nevertheless.That leaves us 192VA.We pair the secondaries by connecting two in parallel. That gives us 96VA per rail. That gives us 4A @ 25.5V per rail. 1/3 of that will be used as charging current. So you are looking into clean 2.5A @ 24V per rail after regulation. This is obviously more than what you need and it seems 150VA transformer hence FB1 will do your job. You do not have to use external +48V.For the VUs you can connect the bulbs in series if you use 12V bulbs. But if you insist on powering them individually you can then fit a second single rail board into the case and set the output to 12V, though you will be wasting quite a bit of energy. The other option would be to use the redundant 8V tap (between 17.5V and 25.5V taps). That will give you roughly unregulated 11VDC.
Are you are the same guy with the Harrison? I'm noticing that most of the caps are rated 25v, and there's one big one in the power supply area rated 20v. My guess is it's going to be 15-18v and not 24. Can you draw a schematic or expand on the area that was the power supply portion? What are all those big caps connected too?
