Phihong USA, a global leader in the development of power-over-Ethernet technology and solutions, has developed. A new single-output mid-span that can power IEEE802.3at compliant applications up to 200 meters (660 feet) from a network switch, the POE33S-1AT-N has been developed by Phihong.
The waterproof POE33S-1AT-N injector has an output of 33.6W at 56VDC and is seen as ideal for applications in harsh environments, including IP cameras and wireless access points. The mid-span is also equipped with SNMP protocol, which allows users to remotely troubleshoot end devices.
“The benefit of waterproof PoE is that users can install them in locations that are difficult to reach and service,” said Keith Hopwood, vice president of marketing for Phihong USA. “By combining the benefits of our extender technology with SNMP, users can enhance their security networks by placing powered devices in remote locations and comfortably troubleshoot from an administrator’s desk.”
The injector supports 10/100/1000 Base-T data rates and is managed by SNMPv2c protocol. SNMP manuals, firmware and MIB functions for enterprise networks can be found at http://midspans.com/pages/support.php. The device features a minimum average efficiency of 73% and bears safety markings for CE and UL. Standard features include over-voltage, over-current and short-circuit protections.
Rated IP67 for waterproof operation, the unit can be safely operated in temperatures ranging from -40C to 60C. The three ports on the front of the device connect to standard three-quarter inch NPT conduit piping. Phihong also offers cable glands for one (PGLAND750) or two (PGLAND750-2) cables to ensure watertight operation. When using outdoor midspans, AC and Ethernet cables must be rated to the appropriate electrical codes for the intended environment, says the company.
