Simucube 2 Pro R2?

Simucube 2
130

Bought a SC2 Pro in January. One 450W power supply. Located in Melbourne Australia if that makes a difference

131

I want to add, that this is when one takes into account the mismatched units on Pro R1 wheel bases.

One “new” news about the PSU situation, is that we are switching manufacturers of the Pro power supply.

  • Some people might find the new manufacturer a pleasant surprise.
  • The new PSU has been tested in similar ways as the previous Pro R2 power supply was.
  • No torque or servo drive tuning changes had to be made anywhere.
  • The new unit is of different size to previous Simucube 2 Pro R2 PSU.
  • The switch was made due to reasons other than reliability. (pricing, availability etc.)

So you are moving away from Phihong?
Back to Mean Well or somebody else?

Would Mean Well be a good surprise to you? :slight_smile:

134

GD and Beano were always pitching it as the best of the best, thus earlier move to Phihong was quite unexpected to be honest.

135

while I can’t reveal the manufacturer directly, we have always liked Mean Well very much.

They just didn’t have a suitable power supply in their catalog back when R2 was put to production.

136

This raises the obvious question: if there’s a power supply vendor you’d prefer going forward, and we’d prefer to have whatever you (the designers) think is preferable, will those of us with existing R2 units be able to order future-spec PSUs?

On one hand, it’s probably a small difference. On the other hand, the number of obsessives who are willing to go to the effort and expense is probably pretty limited, so perhaps it’s something that could be accommodated?

137

its not meant to be a difference at all from product quality perspective, and the warranty periods etc. will be the same.

138

So the specs label will be updated, showing the true max power?

139

We have done a similar analysis of the unit as we did for the original Pro R2 unit.

Also, there has been some PCB changes on Simucube 2 itself to support some alternative components. We still very much live in a world where there is a huge chip shortage.

Due to these changes, we have re-done the CE certification and EMC tests again, for the whole unit, including the PSU.

GST360A enters the room :stuck_out_tongue:

Out of curiosity. If I just order a GST360A 48V 360W PSU will it work on my SC2 Pro R2?

I’m actually asking this because of the resonance noise. Is this noise issue can be related with the power supply? I prefer to keep ffb raw with minimum filter but it’s just make the base quite loud(my wife begin to complain big lol).

142

If the resonance sound isn’t coming from the actual PSU there isn’t any difference.

143

I doubt the psu will make any difference

144

Finally the SC2P PSU is changed, two of my friends had the problem of faulty PSU, so I went to Fanatec. Maybe it’s time to go SC2P for me.

I doubt fail rate is going to be different with any of the PSU’s and there’s still long enough warranty to get a new one if it brakes. Electronics tend to brake right away or if not then til their calculated lifespan ends.

146

Probably you’re right. It was just a guess you know you change your psu and gpu coilwhine stops magically that sort of thing.

147

You mean SC PSU? Never heard a beep from it. Neither from the SC base itself. Only sound from the base is small “hirring” in some occasions. As far as I know it’s a side effect of the used motor. Not of any coils.

148

let’s wait and see because we haven’t seen any news on the psu

I tried this today. I got a GST360A directly from Mouser. In a quick 1 lap test:

  • it works perfectly

  • it does not get rid of resonant noise (nor did I expect it to).

For those wondering, I did this because my existing Phihong unit causes the overload light on my surge protector to light up. I don’t know why, nor am I comfortable poking my multimeter into mains AC to find out. I did a quick test with a Kill A Watt, and while it doesn’t add up to much, not even .01 kWh, you can see the spiking on the real time watts display. I checked a GST280A from my SC2 R1, and it doesn’t exhibit the same behavior. (I didn’t check both GST280As.) I also checked another surge protector (same model, APC P11U2) on another circuit to confirm it’s not the surge protector itself.

My base is out of warranty as of June, and I would have felt ridiculous asking for warranty service with “it works, but it makes a warning light on someone else’s product light up” as my concern.

I run my base at 15Nm, so it’s not much of a workout for this PSU. I don’t expect any issues.
