| 备注 | - PS4820GB-POE-1
The PS4820GB-POE-1 is a Gigabit Power-over-Ethernet (PoE) Injector/Midspan with integral power supply. It provides 48VDC @ 20W of PoE power for multiple* PoE-equipped devices by "Injecting" DC power through the CAT5/6 Ethernet cable. It is compatible with Access Points and other equipment supporting the IEEE standard PoE pinout (Pins 4 & 5 Power + / Pins 7 & 8 Power -) and the 48VDC power requirement.<br><br> *The total number of devices that can be powered will depend on the power requirements of each device used. <br><br> Since the PS4820GB-POE-1 is completely self-contained, a separate power supply and injector is not required. Its compact size makes it ideal for crowded equipment enclosures or for use on a desk top.<br><br> The PS4820GB-POE-1 features built in over voltage, over current and short circuit protection. If an overload is detected, the power shuts down automatically; when the overload is cleared, the power is restored. <br><br> Note: 1 ft. power supply cord sold separately. See PSCORD3<br><br> |
