Does anyone have this information?

Yes, the data sheet has this information.

Thanks, but I only have direct current.

No chance. TL-SG1016D's power supply needs AC.

But I can power the TL-SG1008D with 125Vdc. Can't I also with the TL-SG1016D? I think it only affects the life of the equipment or the performance of the equipment.

Depends on the electrical characteristics of the bridge rectifier, of the circuit design and other things . Furthermore, the TL-SG1008D has an external power supply, while the TL-SG1016D has an internal power supply. If you destroy an external AC adapter, you could easily replace it, but if you destroy an internal power supply, you have to replace the whole device.

I don't recommend to even try it, but you have to decide for yourself.
