Sinamics DCM line voltage supply

Dear Sir,

I have Sinamics DCM 6RA8085-6GV62-0AA0(4Q 600A 600V).

Can I use Sinamics DCM with line supply voltage below its device rated DC voltage? Because line supply voltage in my place is 415V.

Hello frebutrilangga,

What do you mean by below its device rated DC voltage. From your drive MLFB number, its input rated 3 phase AC supply voltage is 575 Volt , 498 A & rated output DC voltage voltage is 600 V, 600 A DC.

You can connect this DC drive to 3 phase AC supply 415 Volt but in such case drive's rated ouput DC voltage would be 432.00 V DC & not 600 V DC.

HTH.

I mean below AC supply voltage (575V)

Does it will be fault (undervoltage),if I connect Sinamics DCM (575 VAC Supply) with 415V actual line voltage?

Thanks.

No.

User has to enter converter armature rated input supply voltage in P50078[0] (in your case 415 Volt) & converter rated input field supply voltage in P50078[1]

HTH.

Thanks you so much.
