Output voltage from mains driver?

[A_Camera]

Hej!
Thank you, interesting to see!

Hej igen!

Thanks.

The Leadshine DM2282 is a "mains" driver, ( 220V.)
If I would have used the AM882, the stepper would have got about 75V.
That’s a little more than the calculated max (66 V) but i guess it would have worked.
With the DM2282 I get more margins and I won’t have to build another PSU so the cost will be about the same.
I know it works because I can see it being recommended here and there but I can’t get what the output Volts will be?

The way I interpret the manual of the DM2282 is that it can use DC or AC supply. The DC input range is 115~305VDC and the AC is 80~220VAC. It is NOT the mains you normally connect to the input directly, but through a transformer.



I see two major reasons for this, one is personal safety, the other is that the mains in Europe is NOT 220V, so I would not connect it directly to the mains. Basically, if you want to build a PSU, that's fine, but regardless of which, you don't need it if you use the DM2282, you just need a transformer, but if you build one you can still use the DM2282 because it can use both DC and AC supply.

Here is a link to the manual, in case you have not seen it yet:

My guess is that the output voltage will be (if using AC as supply): 1.41 x the AC supply voltage. If DC supply is used then the output will be the same as the input voltage if measured as I measured the voltage.
