Right, silly me.
Everything got rearranged.
Thanks for the explanation Mika.
You said “The peak power consumption is digitally controlled and stays within the same parameters for all Simucube 2 Pro models.”
Can I ask if the peak power limit has been modified/changed for all units to incorporate the introduction of the R2 psu?
The reason I ask is that these limits have me wondering if we older users could theoretically use a just a single 280W R1 psu. I suppose it’s more complicated than I’m making it sound…
No, that single PSU is not sufficient to drive the unit to 25 Nm. Also the peak power consumption is digitally controlled and has been tuned specifically to be a fit to the PSU setup in the Pro model, and thus you would get PSU overcurrent shutoffs even if you scaled down the max torque.
As reported in another thread, the peak power is consumed in not so obvious situations in the servo motor system.

Are we saying that all SC2 Pro units are digitally limited to 450Watt Peak power?
A bit confused on how you could use telemetry to tell that it never exceeds that number if it was limited from the get go?
Is there by any chance a way for end user to access that telemetry data, I remember the questions were raised in the past on how to check if the unit produces the power it should.
Some Nm telemetry graph would be awesome.
Yes, all are now. We did lower the power limit in a firmware release quite a while ago and nobody noticed anything. This confirmed our suspicion that those telemetry events that exceeded that level were very rare (which was 100% proven, clear as day in the data) and were related to e. g. full torque right while user was also turning right and thus not measurable/feelable in practice at all.

Just out of interest, are you able to tell us what the peak power limit was before the firmware change that you mentioned?
Well the Mean Well PSUs have over current shutoff with very little tolerance, and we had some reasonable margin there as well.
Thanks for all the replies, Mika. I’ll be interested to see the results of your future tests in regards to seeing if this R2 psu could be paired with the original SC2 Pro without the need for a splitter cable 
@ Mika
Just curious.
What % of SC2 units sold are you getting telemetry from?
Is it still something that you have to opt into, or are units automatically sending data?
Its opt-in in the True Drive software.
I can’t reveal the percentage.

Ok understood you can’t release.
The only reason I asked was I was wondering if you were basing your desicions by analyzing data from the majority or minority of actual users.
Thanks for the response
You did lower the power limit in a firmware release quite a while ago.Does it mean that the old device had made a sacrifice to be compatible with the new one? So Reduce the original better performance? Because the old equipment has a higher power supply than the new one. And the price of the new equipment is lower in Augury. For old device users, we want to get the full power of the wheel base, even though we may no feel of it. Thanks.
You are still getting the full power, the same FFB quality and experience, and same torque while driving, no worries. The performance is exactly the same.
Just to add, that the percentage was closer to majority than a minority. Very much enough to make conclusions on how the devices are being used.
Sampled majority, not everyone has telemetry enabled.
I’d suspect anyone with any sense of privacy has it disabled.
A bit disheartening to learn that you silently rolled this change out without any mentioning in the release notes. What that artificial limit buys for R1 owners?
I remember a while back Tommo was saying that SC2 Pro needs at least 450watt, but now it’s at most.
I hope we are still getting advertised sustained Nm.

All interesting…
Have to say looking at the back of the new product im actually super pleased I got the old version this week (I knew beforehand when ordering also)
Coming from a DD1 it surprised me how small the two PSU’s for the pro are in comparison (new single PSU looks massive again)… I printed this bracket (https://www.thingiverse.com/thing:4596033) to hold them together as one and mount in the bottom corner of my rig in the same place I mounted the old Podium PSU. Looks super neat.
And also coming from the podium I really appreciated the power ‘Switch’ on the back which is super easy to find and has a very satisfying click to it… also the bright LED that shines on my cables so I can glance around and clearly see it on… looks like the new one has a different tiny power button in the middle very much like the Podium which I didnt care for and the LED being built into the PSU connector housing just isnt as good as a dedicated LED imo.
Either way its very small points, I would have been super happy with either unit arriving frankly.

Good point on switch, on R1 I can easily reach the back of the motor without getting out of the seat as it’s in a lower left corner. The new one smack dab in the middle, surrounded by antenna and cables.
Sounds like the best is the enemy of the good situation.
It’s a little weird hearing about the limiting having been put in.
I was feeling this some time back, that it felt “weaker” than I remembered it. But I put it off to a combination of me remembering wrong/that maybe something somehow semi-broke in my base or that I had gotten used to the force and gained some strength using it…
From my understanding of the posted I should not be able to feel that, but just putting here that I had this experience of thinking it felt weaker…
I am not saying I am sure this is what caused the feeling or that it actually was a correct feeling of mine, only that I had this sensation and it has lingered with me, please don’t read me wrong.
It could very well just be the case that I got used to the forces. But it’s still a weird coincidence.

Mika mentioned “Only we can get this version of the PSU. It is custom made.”
Was the old 2x280W version using “standard” PSU and in case that PSU failed I could just go online and order one?
What is the case with this new custom made PSU? I’m sure that during warranty period it won’t be an issue to get replacement, but what about after that, will this be available to purchase through resellers and is manufacturer still making these custom PSUs in case that we will for example have Simucube 3 (and Simucube 2 is phased out)?
