One thing that is very cool about the supplies from FeatherMerchant is that have active power factor correction. At least the 47a supplies do, I haven't tested the others. If your are running the supply off a generator, that will alow to get away with a smaller generator. Or multiple supplies off the same generator.
I don't believe the Iotas have APFC. Some models of Meanwells do, but they are significantly more expensive than FM supplies. |

i need another power supply...ive had the 42amp from feathermerchant for over a year...thing just quit on me at the field a couple weeks ago....ive been pushing it as far as my hyperion duo will let it on 2 6s5000 packs,usually 6-6.5amps per battery...started using a cheapo 2stroke generator from harbor freight 3 months ago ..do you guys think i killed it from the generator? or from over loading the supply?
thanks, matt |

If I may - I have used my clamp on meter to read amps from my 12V supply to my Hyperion Duo and read 26A when charging two 6S 5000 packs full out which is about 6.5A
If that's all you're doing it should not b a problem as far as load. Now the generator may be a different matter. The supply is rated for 120/240V operation so I doubt it is over voltage but if the output votage of the generator changes a lot it would cause the power supply to have to work to regulate the output. I don't know if that would affect its life or not. |

think it was the genny, it'll load up quite a bit when trying to get max out of the charger...watching the charger v.input it goes from 10.8-12v...genny is only rated at 800w-900w max....it'll run at constant 12v with smaller packs at 1c charge rate all day.

Yikes. I wonder what te input Voltage was doing?
There is a fuse inside the case near the 120V input. You can pull it and test it. |

Nope. In fact some of the output components are only raeted for 15V. These were built with one thing in mind and that is running a file server at 12V.

i just sent you an email.
do you have a 47A available? |
|
|
|
|
|
Yup. Got plenty.

That depends on the supply. It could be quite lengthy. The circuit boards are mounted to the chassis on metal standoffs which all could serve as grounds. Several grommets could be used to isolate the board. Do you want to buy a pair and experiment?
