Location A: if the Unifi no connected to other PCs via wired LAN cable. Whole setup you can use TRM-NIF-3 for power protection only.

Location B: Whole setup involved with power source only, you can use TRM-NIF-3. As the vacuum cleaner, I recommended to use separated power source instead due to high power requirement, you can use SC0039 for bypass the existing power cord.

Thank you for your reply. For Location A even if Unifi is using optics cable can use that setup?

Can you PM me quote for 2x TRM-NIF-3 please. May I know how long is the cable for this? Not sure if 3 plug points are enough. If not enough I need to use extension might be too many bulky items in small space. In that case is it possible to use SC0039 then use regular extension?

Thank you very much for your prompt response.

May I know the difference between these?

1) SC0039 and MDSC0039
2) SF9512DSL and SF9812-ARD

I have this setup:

A: wall plug + telephone wire > Modem > Router

B: Wall Plug > Wifi repeater

For B: I think I can use SC0039 as it is a standalone device.

For A: Should I use SF9512DSL or SF9812-ARD? My unifi speed is 20Mbps.

you can use SC0039 for WiFi repeater if it no connected with any physical wire
the Unifi connect via copper RJ11 connector?

Correct.
