Cudy POE400 PoE-sovitin Gigabit Ethernet 56 V 90 W

The Cudy POE400 is a compact PoE adapter that provides Gigabit Ethernet connectivity with a 56 V output and up to 90 W total power. It supports IEEE 802.3af (PoE), 802.3at (PoE+) and 802.3bt (PoE++) standards, offers a maximum operating distance of 100 m and includes LED indicators for PoE and power status. The unit has two RJ-45 Ethernet ports and a wall-mountable design suitable for small office and home network deployments.

Advantages

The POE400 supports multiple PoE standards (802.3af/at/bt) to power a wide range of devices and delivers full Gigabit Ethernet throughput. With a 56 V output and up to 90 W capability, it can supply sufficient power for cameras, access points and conferencing equipment. The adapter is compact, provides LED status indicators for easy monitoring and is designed for convenient wall mounting.

Suitable for

• IP phones and VoIP conference systems
• Indoor Wi‑Fi access points (802.11n/ac/ax)
• Simple and PTZ IP surveillance cameras
• AV-over-IP encoders/decoders and powered speakers
• LED ceiling lighting panels (PoE++ compatible)

How to use

Connect the POE400 to your network switch or router using a Gigabit Ethernet cable on the LAN side, then connect the powered device (PD) to the PoE port. Ensure the PD supports the relevant PoE standard (802.3af/at/bt) and that cable length does not exceed 100 m for reliable power delivery. Power the adapter from its external power source according to the manufacturer instructions and verify operation using the LED indicators for power and PoE status.

Recommendations

For optimal performance, match device power requirements to the appropriate PoE mode: use 802.3af for low‑power phones and simple cameras, 802.3at for larger APs and video phones, and 802.3bt for high‑power APs, PTZ cameras with heaters or LED lighting. Keep Ethernet runs within 100 m and use quality Cat5e or better cabling.
