Phihong Intros PSA20U Single-Port Power Injector

Phihong USA (Fremont, CA) has developed a single-port power injector for Power-over-Ethernet (PoE) applications for use with Gigabit systems. The PSA20U is not limited to working only on 10baseT or 100baseT systems, but is compatible with systems up to 1,000 Mbits per second. The output of the PSA20U is designed to give 19.6 W while complying with IEEE 802.3af detection and fault-protection requirements.

The ac input-voltage range for the single-port PSA20U injector is 90 Vac to 264 Vac with an input frequency from 47 Hz to 63 Hz. The maximum output load current is 350 mA and the O/P voltage is 56 Vdc. The device offers a total output power of 19.6 W with fully compliant detection, connection, disconnection, and fault protection per the IEEE 802.3af standard. The adapter features three LEDs that indicate power, connection, and fault diagnostic code to ease installation and set-up. Safety approvals include cUL, TUV, and CE double insulated class 2. Approvals for EMI are EN55022 Class B, FCC part 15 Class B.

The PSA20U single-port injector is priced at $18.00 each in OEM quantities. Parts are available immediately.
