Inyector PoE extra digital POE-004 1 canal 48V 15W para alimentación de dispositivos individuales por Ethernet

The extra digital POE-004 is a single-channel PoE injector that supplies 48 V DC and up to 15 W to one powered device over a standard Ethernet cable. It is designed to add power to a non-PoE link and is typically installed between a network switch and a device such as an IP camera, wireless access point or VoIP phone. The injector complies with IEEE 802.3/802.3u for 10/100Base-T links and delivers power on pairs 4,5(+ ) and 7,8(-) of the RJ-45 cable, supporting distances up to 100 meters.

Advantages

The POE-004 provides a compact, plug-and-play solution for powering a single device without running separate power cabling. It offers regulated 48 V DC output with tolerance 45.6–50.4 V and built-in safety margins, meets required conversion efficiency of at least 80%, and includes protections reflected in controlled ripple/noise and overshoot limits. The unit accepts a wide AC input range (90–264 Vac, 47–63 Hz) and maintains operation in typical indoor environments.

Suitable for

• Powering a single IP camera
• Supplying a wireless access point
• Providing power to a VoIP phone
• Adding power to a non‑PoE network segment up to 100 m

Key specifications

• Inrush current: 40 A max (115 Vac, cold start, full load, 25 °C)
• Output voltage: +48 V DC (tolerance 45.6–50.4 V)
• Output power: up to 15.4 W (load 0–0.4 A)
• Ripple & noise: 480 mVp-p
• Rise time: ≤50 ms; Hold-up time: ≥10 ms at 80% max load, 115 Vac
• Conversion efficiency: ≥80%
• Overshoot: ≤10% above nominal voltage
• PoE wiring: power provided on pairs 4,5(+ ) and 7,8(-) of RJ-45
• Maximum cable distance: up to 100 m
• Operating temperature: 0 °C to 40 °C
• Operating humidity: 20%–90% non‑condensing

How to use

Connect the injector's AC input to a suitable mains outlet (90–264 Vac). Insert the network cable from your switch into the data input port of the POE-004 and connect the output RJ-45 port to the powered device. The unit injects 48 V DC on pairs 4,5 and 7,8 and will power the device up to 100 meters away. Ensure cable and connectors are in good condition and that the powered device accepts 48 V PoE on the specified pairs.

Recommendations

Install the injector in a dry, ventilated indoor location within the specified temperature and humidity ranges. Use cat5e or better cabling for reliable power delivery up to 100 m. Verify device compatibility with 15 W PoE and 48 V on pairs 4,5 and 7,8 before connecting.
