I went with Meanwell SDR for most stuff. I think the thing that sold me
was self recovery from fault conditions.
A lot of power supplies detect a fault and shut off, but then you have
to unplug and plug them back in to recover.
Anyone routinely using a reboot switch to "fix" problems might be
surprised how often the reboot isn't really for the network device, but
because the cheapo power brick is cranky about an over voltage, over
current, or over temp. Good power supply makes the network happier.

*Subject:* [AFMUG] Mean Well NDR 120-24 & NDR 120-48 for powering
Packetflux Rack Injector?
Last night I replaced yet another Amazon special 29.5V power supply
that was feeding out packetflux equipment. These are defiantly a weak
link and something I need to pull out of the field and replace.
I spent some time today digging into the MeanWell product line and
came up with two options to power our original Packetflux sites along
with the ones now running the rack injectors.
I need but 28V DC and 48V DC at sites feed from 120VAC
I am considering going with the Mean Well NDR 120-24 and Mean Well NDR
120-48 units. Does anyone have experience with these good or bad? Just
looking for something that more stable and reliable at this point.
Thanks,
Brandon
