DescriptionA 24 V 1 A PoE adapter/injector (sometimes branded for iLink or other networking brands) is a Power over Ethernet (PoE) power supply device that delivers 24 volts DC at up to 1 amp (≈24 W) over an Ethernet cable to power compatible network equipment without a separate power cable.⚡ What 24 V 1 A PoE Means�� Voltage & Current:24 V DC output at up to 1 A current, giving a maximum power of 24 W — enough to power many small devices like wireless access points, security cameras, VoIP phones, or point-to-point radios.�� Power over Ethernet (PoE):Sends both data and power over a single Ethernet (RJ-45) cable.Allows devices to be installed where power outlets are hard to reach.�� Passive PoE vs Active PoE:Many 24 V PoE injectors are passive PoE — they always supply power at 24 V to the cable (no negotiation with the device). This is common on older equipment (especially Ubiquiti radios/APs).Standard PoE (802.3af/at/bt) uses ~48 V active PoE with negotiation and is not the same as 24 V passive.⚠ Important: Passive 24 V PoE won’t work with devices expecting standard 802.3 PoE (48 V), and using the wrong voltage may damage equipment. Always check the device’s required PoE spec.�� Typical Use Cases✔ Powering wireless access points (APs), wireless bridges, or network radios that expect 24 V DC. ✔ Supplying passive PoE to security cameras and IoT networked devices. ✔ Using with manufacturers that specify 24 V PoE, e.g., Ubiquiti airMAX / UniFi legacy devices.�� Technical CharacteristicsFeatureTypical ValueOutput Voltage24 V DCMaximum Current1 AMaximum Power~24 WEthernet ConnectorRJ-45Ethernet Data PowerYes — PoE over cablePoE TypeUsually passive PoE, not 802.3af/at/ab standardized active PoEInput PowerStandard AC (100-240 V AC) power adapterTypical UseWireless APs, cameras, VoIP devices supporting 24 V PoE⚡ Passive PoE 24 V injectors often use pins 4,5 ( ) and 7,8 (–) for power, with data on other pairs.
