Hi all

I have a ZyWALL USG 50, but no matching powersupply for it.
The specs state 12VDC 1.5A, but no info about the polarity of the barrell-plug.
Could someone please tell me which polarity the powersupply has? center-positive or center-negative.
If you happen to have such a powersupply I would appreciate very much if you could check what it says on the powersupply about polarity.

Thank you in advance!
Marco

    Even USG60, 40, 20 and 20-VPN had the same polarity. In my experience, a good quality & switching power supply beefier that the amperage requested by Zyxel device won't harm the device itself.
