PoE adapter Lancom Systems 61738

The Lancom Systems 61738 PoE adapter is a compact Gigabit PoE+ injector that supplies up to 30 W (55 V) to a single powered device over standard Ethernet cabling. It supports IEEE 802.3af and IEEE 802.3at (PoE+) and includes an integrated power supply, enabling placement of the power source up to 100 m from the access point while preserving full Gigabit throughput. The adapter is intended for environments that lack built-in PoE or where additional PoE capacity is required.

Advantages

The PoE adapter provides IEEE 802.3at PoE+ power for high-performance access points without reducing network speed thanks to Gigabit support. An auto-sense algorithm detects the required power of the connected device and delivers only the needed amount, improving energy efficiency. The integrated power supply eliminates the need for external power modules; only the supplied power cable is required. Compact dimensions and a lightweight design simplify installation in diverse environments.

Suitable for

• Powering a single PoE or PoE+ access point up to 100 m away
• Adding PoE capability to non-PoE Gigabit switches
• Supplying power to devices compatible with IEEE 802.3af / IEEE 802.3at
• Small office or branch office network deployments

How to use

Connect the adapter to a non-PoE Gigabit switch or a network port using a standard Cat5e or better Ethernet cable. Plug the supplied power cable into a mains outlet (100–240 V) and the adapter. Connect the powered device (for example an access point) to the adapter's RJ-45 PoE output port. The adapter will detect the device's power requirement and supply the appropriate PoE or PoE+ voltage up to 30 W. Observe the 100 m maximum distance for reliable operation.

Recommendations

Use certified cables (Cat5e or higher) and verify device compatibility with IEEE 802.3af/at. For optimal WLAN coverage, position the access point independently of the switch location within the 100 m cable limit. Ensure the mains supply matches the adapter input range (100–240 V) and avoid installing the adapter in locations with excessive heat or moisture.
