I have an AX3 which shipped with the 2 prong European plug and I’ve struggled to resolve this with the seller (the store was UK based). They sent me a plug adapter but it is completely unsuitable for long term use.
I can’t seem to find a UK version of the power supply on its own, and I’ve contacted a few companies who told me that Mikrotik no longer allow them to purchase standalone power supplies.
I’m hoping that someone here can either guide me on where to get the official PSU or a known compatible and reliable after market unit.
Yes, there is nothing special about the mikrotik PSU, any household PSU can be used, some hard drives or other peripherals use the same. Just check if Voltage is within supported range.
I call that one similar but not the same model except for color due to the differing current rating.
I’m in the United States … maybe the question was a small troll on a useful marketing message.
This PA is rated at 1.2A while the one shipped with hAP ax3 is rated at 1.5A (so is the white PA offered by LinITX). Now: product page of hAP ax3 says “Max power consumption 38 W” and since we’re talking about 24V PAs, that translates to even higger current than 1.5A. But I guess most people will go with what producer supplies, in this case that’s 1.5A. I think it’s a bit unprofessional if device producer’s employee suggests (without any disclaimers) a product which is not up to original parts specifications.
@normis, @mkx is making an excellent point and it’s worse than what’s said so far.
My hAP ax3 US PSU has a 1.3A rating. At 15W typical and 24V the draw is 0.625A. IMO I’m good.
But at 38W maximum and 24V, the draw is 1.58A which exceeds 1.2A and 1.5A ratings seen so far.
If MikroTik is serious about that 38W maximum the standard out of the box PSU should be upgraded.
@nickshore Would you be so kind and suggest a product suitable for the high power consumption cases?
@normis Do the applicable product safety regulations allow PSU rated below maximum rated consumption?
There is really no need for more powerful PSU, for eg. hAP ax lite LTE states max current draw of 2.4A yet in my testing with multiple clients, wireless devices streaming video, VPN etc. max current was at 1.26A and that was with CPU at about 60-75% load…
Even if you exceed 1.58A it would be for a short period of time and for a quality PSU 80mA more current shouldn’t be a problem.
A PSU with more amps than spec isn’t going to cause a problem. Voltage is different story, that needs to be between 12V-28V & violating that likely cause damage.
Haven’t tested (and not recommended with regulation) but if you connect the DC jack to a car battery, it likely work fine – and batteries have more amp the difference between the “black” and “white” PSUs.
It is very VERY hard to get a MikroTik router reach the listed maximum consumption. You need CPU working at full load and at the same time, have maximum traffic on all ports.
@normis: the description in your last post makes lots of sense and if it was included as disclaimer in your previous post (about the black 1.2A PA) I wouldn’t have gotten upset about it. Specially if you would have added also some real-life power consumption figures for the particular device @OP was asking about.
When looking at our specs tables, home user will get closer to “without attachments” load. Max is really MAX. If you don’t overload the device, including PoE out, and max traffic on all ports, consumption is in daily life around 15W and 1.2A adapter will be plenty
Max power consumption 38 W
Max power consumption without attachments 15 W
@normis I find your and others reassurances credible and apologize for being unclear about what motivated my alarm.
US law has product liability provisions that some dumb consumer or a cash hungry litigator might try to exploit.
I hope such a thing never happens to my favorite network equipment vendor. Best wishes all!
