I do the same unless there is a larger load on 24vdc.

What are you doing for transient surge protection on the input and

Re: [AFMUG] Mean Well NDR 120-24 & NDR 120-48 for powering Packetflux Rack Injector?

[Mathew Howard]

Most of the time we either do a 24v power supply and batteries plus a 24v
to 48v DC-DC converter, or a 48v power supply and batteries, with a 48v to
24v DC-DC converter (mainly depending on whether there's more stuff that
needs 24v or 48v), but sometimes we'll do completely separate 24v and 48v
power supplies. Most of the newer radios run on 48v, so in some cases,
we're completely 48v, or if we only need to run one or two devices on 24v,
I'll just use the ubiquiti instant 802.3af converters for those.

Re: [AFMUG] Mean Well NDR 120-24 & NDR 120-48 for powering Packetflux Rack Injector?

[Josh Baird]

We down-convert 48V to 24V when necessary (using Traco DC-DC converters),
but that is few and far between these days since old school UBNT and FSK is
mostly a thing of the past.

Re: [AFMUG] Mean Well NDR 120-24 & NDR 120-48 for powering Packetflux Rack Injector?

[Mathew Howard]

The NDR series appears to do self recovery too... the only difference I can
see in features between the two is DC OK relay contact on the SDR,
otherwise the SDR seems to just have a little better specs all around (peak
current, temperature range, etc.). I tend to use the SDR series for more
critical stuff, but I do still use the NDR sometimes as well.

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.

Re: [AFMUG] Mean Well NDR 120-24 & NDR 120-48 for powering Packetflux Rack Injector?

[Ken Hohhof]

I have a bunch of Mean Well HRP-150 and HRP-300, very reliable for wide 
temperature environments, but they are not DIN rail mount.  I do have some 
Traco TSP series DIN rail units, also some Phoenix Contact but they are 
expensive and might just be paying for the name.

Re: [AFMUG] Mean Well NDR 120-24 & NDR 120-48 for powering Packetflux Rack Injector?

[Mathew Howard]

I think the NDR series may actually be the only Meanwell power supplies
that I have had die (outside of things  like lightning strikes that fried
everything)... however, they were definitely abused. I think the SDR series
handles abuse a bit better... at least I've never had one die, and there
must be some reason they cost twice as much.

But in general, the NDR series works well... we have use of them.

So, the moral of the story is that you should always drink beer on the job,
instead of Gatorade?

Re: [AFMUG] Mean Well NDR 120-24 & NDR 120-48 for powering Packetflux Rack Injector?

[Bill Prince]

We have had similar scenarios with subscribers who accidentally unplug
their power injector. They were arrears in payment, and the service
stopped, so they assume we had cut them off. No, you just have to plug in
the injector. Now, while I have you here, how do you want to handle your
service payment?

Re: [AFMUG] Mean Well NDR 120-24 & NDR 120-48 for powering Packetflux Rack Injector?

[Chuck McCown]

Reminds me of a contractor I saw on the street of a small town in Oregon where 
I was the local telephone guy.  

(this is a 40 year old story)

I told him he needs to pay his bill or I am going to have to disconnect.  I 
thought he was going to beat me to death right on the street.  His line had 
been disconnected for weeks.  He was losing all his business etc etc etc.

Once he calmed down I told him that he had not been disconnected at all.  “well 
the phone sure as hell doesn’t work.

OK, then call in a trouble ticket when your phone doesn’t work, don’t presume 
you were disconnected for non pay.

Got down there.  It was a Code-a-phone answering machine made by Ford 
industries.  This was back in the day when the telco owned the phone.  He had 
spilled a beer into it.  That is why it didn’t work.  I cleaned it out and 
fixed it and he paid part of his bill.

If it had been beer rather than Gatorade, you could have fixed it.

We had a 48v mean well doa, well doa when we first powered it on, a jug of 
Gatorade leaked into it and a syncinjector first. Syncinjector was fine

  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,
