Power Over Ethernet Clocks

NOW Available for sale in the European Union !

We manufacture both digital and analog Power Over Ethernet (PoE), NTP-referenced clocks. Click on the pictures below for links to specifications and product information.

All PoE clocks are built to the IEEE802.3af standard which allows the clocks to be powered from remotely located power "injectors" or PoE-ready routers. The ethernet cable carries both power and data to each clock. See Power-Over-Ethernet (PoE) for a more complete explanation.

	Single Cat 5/6 cable for both data and power

Power Over Ethernet - PoE
Power Over Ethernet (PoE) eliminates the need to run 110/220 VAC power to devices on a wired LAN. Using a Power Over Ethernet system a single Ethernet cable carries both power and data to each device.

IEEE802.3af standard defines the specifications to deliver power over standard Ethernet cables. Power Over Ethernet starts with a CAT5 "Injector" that inserts a DC Voltage (48 VDC – max 12 watts) onto the CAT5 cable. The Injector is typically installed in the "wiring closet" near the Ethernet switch or hub. These injectors can be purchased from many different sources or directly from Masterclock. Contact the factory to for details cost and assistance.

All Masterclock equipment labeled PoE compatible or compliant will accept and operate from the 48 VDC that is supplied over the CAT5 cable.
