Phihong's new single-port power injector is for Power-over-Ethernet (PoE) applications, including wireless access points, security cameras and IP telephones. Designated the PSA-16U switching power supply, the device is one of the only single-port injectors to fully comply with the new international standard, IEEE 802.3af.
Power-over-Ethernet technology is an innovative solution to problems involving ac power and the placement of power outlets. PoE allows both power and data to be carried over one Ethernet cable. An access point can operate entirely from the power it receives through the data cable.
By supplying power and data through one cable, security cameras that are located outside do not need an additional “wet location” power supply installed. Office design becomes more flexible using PoE because IP phones can operate on one Ethernet cable and do not require additional power cables. Phihong offers modified solutions that will also connect with legacy IP phones and access points using capacitor or loop-back detection.
AC input voltage range for the single port injector is 90 Vac to 264 Vac with voltage range from 100 Vac to 240 Vac and ac input frequency from 47 Hz to 63 Hz. Maximum output load current is 0.35 A and O/P voltage is 48 Vdc. The device offers total output power of 15.4 W with fully compliant detection, connection, disconnection and fault protection per the IEEE standard.
The adapter features three LEDs that indicate power, connection and faults to ease installation and set-up. Safety approvals for the PSA-16U include cUL, TUV and CE double insulated class 2. Approvals for EMI are EN55022 Class B, FCC part 15 Class B.
Typical pricing for Phihong’s single-port injector is $14.95 each in OEM quantities.
