Hi!
Right now at the Elektron web shop you can buy the PSU-3c power supply. This exact model was included with my Syntakt. In Elektron web is said that this model can be used with all the Digi boxes (DT/DN/SY) and with A4 MKI and MKII. Months before, my Digitone and Digitakt came with the PSU-3b model, that has the same specs printed as PSU-3c. I guess I can use any of these 3 power supplies with any of my machines, Digi or Analog series.
On the other hand, the power supply that came with my A4 MKI is model PSU-3 and have different specs printed in the rear panel. My question is: Can I use the PSU-3 with my Digi boxes safely? Can it fry my small machines?
They should all be essentially interchangable. The PSU-3 can provide a bit more amperage, but the amperage delivered is determined by the load, so all of these should work fine.
There was a previous post of a similar nature which mentioned one has more audible noise, not in the signal path, but in the ambient environment. It could be referred to as âcoil whineâ of the transformer. Iâll see if I can locate the thread.
edit:
Youâll have to browse the thread and see if any information is relevant to you.
Since my original (Analog Four) PSU-3 died, I have been looking into options for replacement power supply units. Based in China, it wouldnât make much sense to order an original Elektron PSU (itâs overpriced anyway), so I went on Taobao and found the power supplies from the original manufacturers of the PSU-3 and PSU-3b, with the difference, that both plugs are 2.1mm instead of 2.5mm (bought adapters) â specs and model numbers are identical otherwise.
As for the PSU-3c, I couldnât find that one. I can confirm that the two PSU-3c units I have for my Digitakt and Analog Heat MKII are indeed making an audible noise. (Didnât notice before). So I wasnât eager to look for those.
As an alternative, I bought a cheaper Delta power supply with matching specs, more or less for the fun of comparing their built quality and noise emittance.
Costs were around 13âŹ
Links to products and specs (for reference, and seems possible to find the 2.1mm plug versions for purchase outside China as well):
For anyone coming across this topic in the future, here are some photos to compare the original Elektron PSUs with the non-Elektron branded PSUs of the original manufacturers (+Delta) mentioned:
They solely differ in the cable and the 2.1mm plug out of the PSU (an adapter to 2.5mm helps)
Other than the PSU-3c, all are dead silent â I tested these three PSUs with the Analog Four MKI, Analog Heat MKII, Digitone, and Digitakt. All working well, had them on for a few hours.
The Delta PSU is smaller, yet delivers 4A, and the built quality seems fairly well. Costs were 3⏠for this one.
Iâd highly recommend using a cable adapter over just a plug since itâs gonna put less stress on the power plug on your Elektron machines. Itâs a pretty neat solution.
Now back on the Analog Four & thus having spare PSUs for live gigs â worth the research.
ANALOG RYTM MKI/MKII, ANALOG FOUR MKI/MKII, OCTATRACK MKII, ANALOG DRIVE, ANALOG HEAT MKI/MKII, DIGITAKT, DIGITONE, DIGITONE KEYS, SYNTAKT
Current Elektron power supply: PSU-3c. These devices were originally shipped with PSU-3, PSU-3b, or PSU-3c. All these devices work with PSU-3 and PSU-3b (With the exception of Analog Drive which doesnât work with PSU-3). The PSU-3c power supply handles voltages of 100-240 VAC, 50/60Hz.
The power supply you want to use must meet the following specifications:
Voltage: 12 VDC
Minimum Current Rating: 2 A
Barrel Connector Size: 5.5 mm outer diameter, 2.5 mm inner diameter
This one shall work fine & specified 4A/48w, it might not even get warm.
And to add to my previous posts:
There was an errata, the Delta PSU delivers 3A, not 4A, yet works without a 2.1 to 2.5mm adapter, is dead silent, and doesnât get as warm as the other PSUs listed.
