I've ordered just about everything I think I'll need to build a 200 Amp 50Vdc Power Supply for this new Solid State Amp project. I estimate that FULL power (will never be used) would require about 132 Amps. So I'm building a supply that can MORE than handle that.
The point in OVERBUILDING this project is most about HEAT - and trying for A LACK THEREOF.
Since I enjoy running WSJT and QRO on EME I want to be able to run 1.5kw with as little stress on all of the components of this amp as possible.
I've come up with a functional (and I think decent) Step-Start design for the 8 each 1200w @ 12v (100amp each) power supplies. Typical server power supplies have a fairly big surge on power up. So starting up 8 of them at the same time over two 240v @ 30A circuits needs to be done gently :-) In order not to trip the breaker. (I think).
I'll post details on this step-start system for the 8 each HP DPS-1200fb power supplies once I've built/tested/and completed it.
I think I've got everything I'll need for this end of the project on the way in here. Should all be here this week by Friday I suspect.
Once I have this new Power Supply built I'll be ordering all the actual BLF188xr bits I need, and spec'ing out / building input/output combiners for 4 of them.
Yeah...I told you this was gonna be a big amp.
