I purchased two Teltonika TSW100 switches to use them as PoE switches for a video surveillance system consisting of 8 cameras.
The electrical system I have is 24vdc.
I ask you if it would be preferable, as I have read in general for PoE switches, to have a 48vdc power source, or the device can work correctly also at 12 / 24vdc.
Furthermore, from the TSW100 data sheet I read:
Input voltage range: 7-58 VDC
Power consumption (idle / max no PoE / max): 2 W / 9 W / 129 W
I would also like to know if the reported electrical consumption is the same both with 12vdc and 24vdc or 48vdc power supply.
Thanks a lot and greetings,
