Mean Well RSP-1500-15 Power Supply

You apparently are missing where it says "17A/115VAC" and "Built-in active PFC function" on the PDF you linked.

The 15 A version has an output power rating of 1500W.

1500/0.87 (efficiency rating) = 1724W in power.

1724W/0.95 (typical power factor) = 1815 VA input apparent power.

1815 VA/115 V = 15.78 amps, which is pretty close to the 17 A (typical) specification.

Silly me! I did a search and saw it right in front of me. Wow. Thanks guys. Kind of sucks in a way though. I don't think the MH is on a 20A circuit BUT the voltage is 122. I'll have to check.

Voltage is 120 at the power supply but the MH is plugged into a 15A circuit. So if I use ken's very handy calculations I'm looking at 15.12A from the Mean Well. Just a bit too much from that circuit.

Look at the RSP-1000-15 instead. That should be good for 80 +amps DC since my rsp-500-15 will do 40.94 amps DC until battery voltage rises to within 0.3v of what I set the voltage at before connecting it to the battery.

You probably could get one of those Shottkeys diodes and perhaps run your Megawatt in parallel with it on the same circuit for 110 amps into that 740 AH L16 bank.

Oh, great idea! Damn, it's $270 on Mouser.

Yeah, that, and it says it is only 750 watts. boooooo!

But two rsp-500-15's and that shottkey rectifier bridge would cost the same or more with shipping.

Or two MegaWatt S-400-12's (36A cont, 41A peak) for $120 total.

You forgot Shipping, and the rectifier likely required to easily run them in parallel.

If I was sure the megawatt did not roll back current, I might have got the s-400, but the rsp-500-15 for me is money under the bridge, and I can dial in 16v when I want, but I can't go below 13.12v. Which was 13.34v before I wired in the 10 turn Potentiometer.

Everything's a compromise, always will be.

Shame they don't make a RSP 1425-14 which could work on a 15 amp outlet and had a range of 12.8 to 16.5v.

Dear MeanWell..... please design such and such a product, and I guarantee 1 person would buy it, maybe.

I'd like those Mean Well's but for the price of that 750W unit I can get the adjustable voltage, PF corrected Powermax 100A. The MegaWatt will indeed need the diode to run in parallel. The one you linked was the one I was going to buy. Shipping is only $5 to my house cause I live near the seller. I wish that 80A MegaWatt did more than 14.5V, I'd get that one. I did send the seller an email asking about specs. Will post his response.
