RB/1100AHX2 Routerboard Power Supply Question

I would like to use the RB/1100AHX2 Routerboard and possible some of the Cloud Core routers in areas where I have typical 120 VAC power and also in area’s where I will power them from a 125 VDC battery.

My questions are:

  1. Will the RB/1100AHX2 Routerboard accept 60 Hz 120 VAC power?
  2. Will the RB/1100AHX2 Routerboard accept 125V DC Power?

I see from the Power Options in the Brochure is says “Built-in power supply (IEC C14 standard connector 110/220V)” which doesn’t say AC or DC power.
From the Manual is says “Power at the case IEC C14 jack: 110-­220VDC” which looks like it will take DC power, but not sure about AC.

Thanks for any help on this!

Hi SCADAman,

  1. Will the RB/1100AHX2 Routerboard accept 60 Hz 120 VAC power?

Yes.

  • RB1100AHx2 integrated Power Supply:
    [] INPUT: 110/240V AC 50/60Hz 0.8A
    [
    ] OUTPUT: 12V DC, 3A

Here you can find this infos: RB1100AHx2 and Power Supply Spare-Part

  • Cloud Core routers integrated Power Supply:
    [] INPUT: 110/240V AC 50/60Hz
    [
    ] OUTPUT: 24V DC, 4A

  1. Will the RB/1100AHX2 Routerboard accept 125V DC Power?

No.
But you can use a DC/DC Converter, for example with input: 72V - 150V DC / output: 24V DC, 3A to Passive PoE 12-24V DC on Ether13 (not 802.3af/at conform)

Thank you for the info networx!

I may try to find a replacement for the PSU in the case and put a DC-DC converter in there. Not sure if I will find one that lines up with the same hole in the case or not.

Do you know what type of connector is on the routerboard that the PSU is plugging into?

Hi SCADAman,

Do you know what type of connector is on the routerboard that the PSU is plugging into?

On Routerboard: Connector 3-Pin, RM 3.96mm

On PSU DC cable: Crimp Terminal Housing 3-Pin, RM 3.96mm with two Crimp Terminal for AWG 18-24 Cable

Here a “build-in-ready-solution” for external PSU: DC Power Cable with a DC Terminal

But I personally would prefer a solution like this: PoE - RB/GPOE passive Injektor with a DC Terminal
Because you don’t have to modify/opening the housing or lost warranty.

you are not voiding your warranty by opening case or swapping out the PSU.

You will void warranty if you damage the router and/or you “attack” router with the soldering iron.

Sounds good. Thanks for all the help!
