Ethernet Direct Corporation has launched CUE-500 Industrial Power over Ethernet switch complying with IEEE 802.3af standard.
The Cobra CUE-500 is a hardened Industrial 5-port Slim Unmanaged Ethernet Switch. It supports four PoE injector ports classified as power source equipment (PSE). CUE-500 provides 15.4 watt of power per port and can be used to power IEEE802.3af compliant powered devices (PD) by Ethernet cable and eliminates the need for additional power wiring. The compact, slim line switch is equipped with a relay output for an event alarm for easy troubleshooting. It offers a 12~ 48 VDC redundant powers input design and is secured with Power Polarity Reverse protection and an Overload Current Reset-table Fuse. The IP-30 housing protection, wide operating temperature of -10 to 70 deg C and DIN rail mounting makes CUE-500 suitable for an industrial environment. The E version extends the temperature rating to -40 to 80 deg C.
Power over Ethernet (PoE) has been standardized with IEEE standard 802.3af describing Ethernet power-sourcing equipment and powered terminals. This specification describes delivering 48 volts of DC power over unshielded twisted-pair wiring. Nowadays, more and more Industrial applications are starting to benefit from electrical power sent over Ethernet cables. This avoids a separate power cord for things like internet phones and wireless access points. The so-called PoE injects power into an Ethernet cable at the source and receives that power at the destination. Both the injector and receiver are embedded into the device.
