Phihong's POE30U series midspan

Phihong USA's 30W one-port midspan, designated the POE30U series, is designed to power wireless and WiMAX access points that require up to 24W power. The device is being implemented in applications supporting IEEE 802.11N, the new broadband wireless standard whose access point power requirements are much higher than those of current IEEE802.3af standards.

"802.11N access points with A/B/G support and new WiMAX access points are typically using up to 24W of power," said Keith Hopwood, VP of marketing for Phihong USA. "By using our high power midspan, there is no need for installing new local AC power outlets and special wiring, eliminating the cost and time delays of calling an electrician."

In addition to wireless and WiMAX access points, applications for the POE30U midspans include IP telephones with streaming video and high quality Pan Tilt Zoom.

The 30W midspan features diagnostic LEDs and the same safety and protection systems as with the IEEE 802.3af standard, including detection, disconnect and overload control. The device is also Gigabit-compatible.

DC output voltage for the one-port midspan is 56V with accurate overload detection to 0.55A. The outputs are equipped with short circuit and overload protection, and the output can be shorted permanently without damage. AC input voltage range is 90Vac to 264Vac, with voltage rating from 100Vac to 240Vac and AC input frequency from 47Hz to 63Hz.

Phihong's POE30U midspan has been tested for compatibility and broadband data handling capability by UNH IOL. Safety approvals for the 30W one-port device include cUL/UL and CE.
