If you're using Meanwell, then yeah RSD is what you want.

Yep, they definitely have a 24v power supply (RouterOS reports the
voltage as 24v, even). I would guess that they won't run on higher
voltage because they use quite a bit more power than the 1009.
If you need to run them on 48v, it's probably best to just use a DC-DC
converter and be done with it. In fact, I bet you could even fit
something like a Meanwell RSD right inside the case in place of the AC
power supply.

It’s possible they could also accept 48 volts, but without some
assurance that’s true, I wouldn’t risk it.

We already have 1016 and 1032 at all our sites. Therefore I would
like to use them. +48v would be great!!!!

I'm pretty sure the 4011 doesn't have an internal power supply. I
think it's just got a normal AC adapter, like 2011 and 3011. it'll
also take 12-57v (same as the 1100AHx4, I think).
There's at least one model of CCR (a 1009, I don't know if they
ever did that with anything bigger) that's made for DC and doesn't
have an internal power supply.

If you’re willing to downsize a bit from the CCR, the 1100AHx4
has a 48VDC terminal block on the back in addition to 2 AC
power supplies. It has switch chips though, each Ethernet
port isn’t connected directly to the CPU, so there are some
2.5 Gbps bottlenecks, plus it has less total CPU horsepower.
It also seems a shame to waste the AC power supplies. Makes
it easy to power them up on the bench though. The
soon-to-be-available 4011 has the same CPU but AFAIK doesn’t
have a DC power input except maybe for POE.

Yes I've done that many times.
I don't know what their acceptable range is, so I use a
regulated DC-DC converter to give it exactly 24V. I've used
Meanwell and Traco coverters.
I drill a hole in the back of the CCR case and feed a heavy
jacketed 16/2 through it and secure it with a zip tie on the
inside of the case. There are two tiny holes near the corner
that are just right to feed a little zip tie through....I'm
not sure what their actual purpose is, but they are perfect to
secure the DC cable.
The polarity is not marked on the motherboard, so I always
verify the polarity of the existing power wire and mark a + on
the white plug with a sharpie. I leave the AC brick in their
with the DC side cut off and taped up. My thinking is that if
I had to I could reconnect the AC brick.

Is anyone powering Mikrotik CCR routers from DC. It
looks like if you pull the included AC PSU it feeds the
Tik with 24volt DC. So can we just remove the supply and
feed the tik from a 24v DC supply? Anyone doing this?
Anyone know what the make / model of plug on the PSU?
