Power Supply envy, anyway!

3600W @ 48V plugged into two 20A dedicated circuits, should provide enough juice for whatever new charger I get (probably will be DPL8)

Not only will that charge, but I think you can weld with it too!

Nice!

Yeah, you might just be able to strike an arc with that. Weld up a tent frame at your club while charging your rx packs.

Two 20A dedicated circuits ?

Why didn't you connect the inputs as a single 220V 20A circuit with neutral ?

At least that way your load on the house circuit will be balanced.

My new power supply cost $27 shipped from eBay. Ten minutes of soldering and another ten minutes to make a power cord has me up and running. 51.5v at 57 amps is perfect for my iCharger 4010duo running at 40A per channel. Not fancy, but certainly effective. I DID run a dedicated 220v service out to my charging location OUTSIDE of the house. No more house fires for me.

I am still considering that, but thought I would need at least 30A (they are 7.8A each on 220V) I haven't run the circuit yet so everything is still an option. Also not sure if any other modifications, to the supplies, are necessary to run them on 220V.

I would leave it the way you have it. If you run 2 120v outlets from alternate breakers (one on each leg), then you are running the pair on 220V (each at 120 with neutral between the 2). The 2 lines coming into the house will be balanced. Would still work if not balanced but might as well balance it if you're installing outlets for it anyway..
This way if you bring it somewhere and only have one 15 or 20A, 120v duplex outlet, you can still use it...just at reduced load so you don't trip the breaker.

This is a big and heavy powerhouse. Advantages are as follows:

One unit
No floating or safety issues
Quieter than smaller multiple fans
Easiest pin out and soldering needs I have ever seen
Steady output
Internal adjustable pot for voltage, but I left it stock
Cheap

Disadvantages:

Not portable
Big
Heavy

Yep...they are so quiet (unloaded) I can't even hear the fans, I have to check the lights to make sure they're on.
The 2 lines coming into the house will be balanced. Would still work if not balanced but might as well balance it if you're installing outlets for it anyway..
I'm not too worried about balancing the load, it's a 40 ckt 200 amp panel that's almost full...so it has plenty of load on both buses.

My concern now is the voltage output, I can only get it adjusted down to 47.3 volts, the DPL8 that I'm planning on using says 48V input max...
Am I too close?
Should I go back to three?
I should be able to get almost 39V, which is probably enough.

If one should fail could it damage the others? I often hear PSU's connected in series and parallel can be a bit tricky depending on their design.
