Mean Well power supply for my usage
I've been reading old threads for a couple of hours. I'm fairly sure a Mean Well p.s. can do what I want to do, but I'd appreciate if one of you early adopters can point me to a specific model, etc. ...

75 amp 3 Stage Charger
KEY FEATURES:
Automatic three-stage battery charging maintains your battery's life with three nominal voltage output models:
* 13.2 Vdc range "float" mode
* 13.6 Vdc range "absorption" mode
* 14.4 Vdc range "bulk" mode
* Electronic current limiting automatically shuts down power during overload or short-circuit conditions.
* Quiet operation in a wide range outputs. Convenient deck mount installation.
The PM3-75 Amp converter/ charger is a versatile, advanced power source solution.
Some of you are familiar with this unit. Voltage rises slowly as batteries charge to 14.4 volts. After this unit reaches 14.4 volts how long does it stay at 14.4 volts before it decides to do something weird?
-An Educational Moment-
It drops to 13.6 as soon as it gets to 14.4. See my ugly graph of that with the 100amper.
Similar to the Iota which drops to 14.2 15 minutes after it gets the batts to to 14.6 (converter 14.8)
That is why I modified my PM3-100 amper to go to 14.8 using its internal pot. Now it gets the batts to 14.8 and stays there forever till I shut it off. ( I use the trailer's converter at 13.8 or a little 2amp charger I have that holds forever at 13.4 to Float)
With the PM adjustable, you can do that with the external knob. When it has done the job at 14.8, change it down to 13.x for Float
Note that Randy's PMs have different specs from regular PMs and PMBCs.
