Brad, the meanwell power supplies will basically allow the person charging batteries to maximize battery charging int he time the generator is running, for much less money than a programmable high amp charging source like xantrax truecharge
3 or 4 stage smart chargers/ converters seek a fixed voltage and only hold it for a certain timespan. this timespan is inadequate 99% of the time.
The meanwell will allow the user to set absorption voltage and it will ramp upto full power/ full output until battery voltage gets very near the preset voltage chosen, then the voltage will remain there and amperage will taper. this is the absorption limit of the battery and a battery can be charged no faster without increasing voltage further, which one should not do..
No these do not come with power cords, they are meant to be installed in sources requiring 13 to 18 volts where one would not want 6 feet of powercord floating around. They are designed like a house outlet with romex going right to the 3 terminals.
Not sure about the pin jumping on the rps 750-15 model, Will look into it. I do not bother with the extra features on mine such as compensating for voltage drop on the lines.
NO voltmeter, no ammeter, these are brute force chargers, likely as capable or more so than the wheeled chargers at mechanics shops, but with the ability to fine tune end voltage.
Regular converters require the end user install the DC wiring output, these meanwells require the AC side be provided too.
I cut off an old HD powerstrips 14 awg cord, but a 12awg power tool replacement cord would be better.
the meanwell rsp series is also power factor corrected, meaning they use the AC electricity more efficiently, which might mean less gas burned in the generator. for the same or more battery recharging occuring.
My rsp-500-15 has a voltage range from 13.12 to 19.23v, much wider than the spec sheet claims. trojan now moved their recommended voltage to 16.2v. The meanwell has no issue seeking and holding this voltage as long as the user decides.
there are threaded insert all over the body of my meanwell. For metric screws, i forget which size. I took mine into ACE hardware and found the screws which would thread into these threaded receptacles, and made my own mounting feet and also on the bottom used aluminum screen edging to attach the power cords and DC outputs to take all stress off of receptacles on meanwell, as mine is mounted on my electrical cabinet door.
Readers can peruse my thread on my Meanwell rsp-500-15. This unit can output 40 amps all day long at any voltage between 13.12 and 19.23 as I choose. I added more ventilation and heatsinking and a better voltage adjusting potentiometer to make it the world's best manual 40 amp battery charger. the rsp-500-12 would not allow the 16+ volts required for equalization and perhaps not the 14.8v absorption voltage either.

I brought up the possibility of using the Meanwell rps-750-15 as Mobilesport wants to max out his generator and battery charging in the time he decided to run the generator. Setting a 14.8 or higher voltage allows this, without having to resort to trickery or having an automatic charging source prematurely drop charging voltage, slowing charging greatly while still burning gas in the generator.
I plug in my meanwell to AC, then adjust DC voltage unloaded, then connect 45 amp anderson powerpole to a direct feed to battery, and Boom instant 40 amps when the battery is depleted, and 40 amps until battery voltage climbs to near what I set it at unloaded. It does get hot at maximum output.
If one plugs in the meanwell, sets the voltage then puts an alligator clamp on a battery terminal, there might be a spark, but one could also put the clamps on the battery first, then plug in the Meanwell and in a second it will start outputting full current.
I'd caution against starting and stopping it quickly on depleted batteries. Could be cumulatively damaging as it would be to any converter or automatic charger.
They make 24 and 36 and 48 volt versions too Brad.
Knowing how many amps are flowing is great. When amps taper to a certain level at absorption voltage, one can infer their batteries are at 80+%.
Many inexpensive ammeters can handle 60 amps. this one has a built in voltmeter.

Shop around.
i use a GTpower wattmeter with 8awg leads on my 40 amp rsp-500-15 to count amps voltage watts AH and WH and some other figures, but this wattmeter cannot handle the output of the rsp-750-15 model
If one wanted to seem more than the amps but something that coule count KWH Something like this could count that figure has produced:

I do not own this meanwell 750 watt model ot the link just above but I did set up the Drok Ammeter/ voltmeter combo on another project and it read close enough until low amperage below 1.5 amps, but at 40 amps it was accurate enough

I have charged my 90Ah northstar AGM with 40 meanwell amsp and 25 schumacher amps at the same time, but I have to bump meanwell voltage to 15.3v to keep it at both at maximum output until battery voltage measured on terminals climbs to 14.4 to 14.7v.
) is not a charger, so I need one.
