UPS suggestion compatible with Switzerland connector and standards

[Naweap]

Hello,

I recently built my own NAS which I installed TrueNAS SCALE on.

I'm looking to buy a UPS in order to preserve my NAS from the electricity network micro interruption and instability.

Do you guys have any recommendation for a great UPS? Please note that I'm currently living in Switzerland. That said, the UPS has to be compatible with Switzerland connector and standards.

Thanks in advance for your replies.
