Microsemi's new POE midspan device delivers 60 Watts of power

Microsemi has released 60W Power-Over-Ethernet Midspan with gigabit switching support. This device is fully compliant with IEEE 802.3at (Draft 4.1) standards and delivers power over all four pairs of Ethernet cable enabling it to maintain low current of 600mA in each wire for delivering 60W power.
Microsemi suggests to use this PowerDsine PD-9501G device for many advanced PoE Powered Devices (PDs) including 802.11n Access Points, WiMAX CPE and base stations, Pan-Tilt-Zoom cameras and thin clients that require high power and support of 2-event classification as specified in the latest IEEE 802.3at specifications.

"With Microsemi's PowerDsine PD-9501G, we continue to deliver on the promise of the emerging 802.3at standard, enabling our customers to get the best possible functionality out of Power over Ethernet," said Sani Ronen, senior product line manager for Microsemi PowerDsine Midspans. "This new Midspan offers a combination of high power, gigabit support and 2-event classification. It is a pioneering solution in a PoE market where, until today, the barrier to PoE adoption was its restriction to 15.4W and 30W, respectively, in 802.3af and 802.3at applications. ThePD-9501G will enable a host of new Ethernet applications to take full advantage of the well-known PoE benefits at 60W power levels."

The PD-9501G can be used to power 2-pair devices with up to 30W. In this case, the midspan still uses all four pairs of CAT5-and-above cable, which enables it to dissipate up to 50 percent less power on the cable.
Microsemi says, A PoE system using the PD-9501G will consume almost 15 percent less energy than a conventional 2-pair solution, which translates into savings of approximately $25 per year per powered device, assuming energy costs of $0.10 per kilowatt hour (KWH).


The other features include 2-event classification, 10/100/100 BaseT support, and unique interlock mechanism.
