DC-powered PoE Midspans for Access Points and Security Cameras

October 28, 2013 by Jeff Shepard

Microsemi Corporation today announced the availability of two new dc-powered Power-over-Ethernet (PoE) midspans, PD-9501G and PD-9501GO. The devices provide cost-efficient standalone solutions for powering LAN access points, security cameras, IP videophones, thin clients and other high-power applications in dc environments — such as solar-powered environments and traditional telecom environments. Microsemi's new single-port midspans can be powered by dc power ranging from 10-60 VDC and provide standard PoE power to applications requiring 15.4W, 30W and 60W of power.

The PD-9501G is designed for indoor use and the PD-9501GO was developed for outdoor installations. Both devices feature a convenient plug-and-play installation and provide significant energy efficiency and cost savings. In addition, the devices' dc input versions eliminate the need to double convert power, offering an eco-friendly and more efficient way to power devices without the need to convert ac to dc.

"Our new PoE midspans fulfill today's need for devices to be powered by dc, as utilizing energy from solar panels or in telecom locations can often require this type of voltage level," said Sani Ronen, director of marketing for PoE systems at Microsemi. "Microsemi's dc-powered solutions eliminate our customers' need to use ac or an external dc to ac power converter with ac midspans."

The PD-9501G is designed specifically for high-power Ethernet end terminals with 60W of power, and is backward compatible and safe to use with any 802.3af terminal. The PD-9501GO offers an IEEE802.3at-compliant solution for outdoor installations, guaranteeing 60W of power and ensuring safe and reliable operation for any standard PoE data terminal. It also offers surge protection ensuring indoor equipment is safeguarded from outdoor power surges. Both midspans allow devices to receive power, along with data, over standard Ethernet cables, leaving network infrastructure completely unaltered. Microsemi's PD-9501G and PD-9501GO's dc-input versions include: PD-9501G/24Vdc; PD-9501G/48Vdc; PD-9501GO/12-24Vdc; and PD-9501GO/48Vdc.
