["The ALL-MC302v2P2WIRE set offers you the option of setting up both data and PoE via a 2-wire connection. The maximum cable length can be a maximum of 500m. The master must be powered by a power supply and supplies both the slave adapter and the PoE end device on the slave with data and power. The set is suitable for upgrading analog systems through an existing cable infrastructure. The compact size of the media converter is perfect for replacing old door stations with a new IP door station. The Mean Well GST60A48-P1J GST constant voltage power supply is a reliable high quality voltage converter to convert the AC input voltage into a single output DC voltage. This model works with 60W/48V. Constant voltage mode power supply Power adapter Fully insulated plastic housing, IP64 Free air convection cooling Class 2 power supply Actual data speed and PoE performance may vary depending on environmental conditions and cable quality.
