Phihong USA has developed a new single-output midspan that can power IEEE802.3at-compliant applications up to 200 meters (660 feet) from a network switch. The waterproof injector, designated the POE33S-1AT-N, has an output of 33.6 W at 56 VDC and is ideal for applications in harsh environments, including IP cameras and wireless access points. The midspan is also equipped with SNMP protocol, which allows users to remotely troubleshoot end devices.
Phihong's new power injector supports 10/100/1000 Base-T data rates and is managed by SNMPv2c protocol. 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 -40°C to 60°C. The three ports on the front of the device connect to standard ¾" 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.
Installed in the included mounting bracket, the new injector measures 300 mm (11.81") x 184 mm (7.24") x 82 mm (3.23") and weighs 2.8 Kg (6.24 lbs).
