FAQs
Q1: What is the Ubiquiti INS‑3AF‑USB used for?
A: It is a PoE‑to‑USB adapter that converts standard 48 V 802.3af PoE power over Ethernet into 5 V DC via USB, allowing USB‑powered devices to run from a PoE switch or injector.
Q2: What are the power input and output specifications?
A: The adapter accepts 48 V DC PoE input and outputs 5 V DC at up to 2 A via the USB port.
Q3: What physical and interface ports does the INS‑3AF‑USB have?
A: It has one RJ45 port (for PoE in) and one USB Type‑A port (for USB output). The unit is compact — Ø 30.2 mm × 95.3 mm and weighs approximately 60 g.
Q4: What protection features and operating conditions does it support?
A: It includes ESD/EMP protection (air discharge ±8 kV, contact ±4 kV) and is rated for operating temperatures from 0 °C to 40 °C.
Q5: What kinds of devices benefit from using the INS‑3AF‑USB?
A: It’s useful for powering USB‑based devices — such as cameras, small routers, IoT gear, or other peripherals — especially when you only have PoE available in the environment and no standard USB power source.
