PR4100 Power Supply

#1

I understand the requirements of a PR4100 power supply are:
19 Volts
4.74 Amps
90 Watts

But I also need to know the polarity of the centre pin of the DC jack and the diameter of the centre pin of the DC jack to enable me to source a replacement power suppy.

Thanks.

You should be able to purchase a power supply from the WD Store.

Good day.
I just contacted to WD distributers in our region and got information that WD doesn’ t sell power supply units for PR4100 separately. In case if NAS owner will need to use both power supply sockets they should looking for any alternative manufacturers.

Best regards.
