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).
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.
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.
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.
