The Instant 802.3af Adapter transforms almost any Ubiquiti PoE (Power over Ethernet) device into a fully compliant 48V, 802.3af-compatible product. PoE Switch Compatibility The Instant 802.3af Adapter works seamlessly with a variety of 802.3af switches for remote power control applications. As you manage and monitor your network, you can conveniently power or power cycle your remote devices using your 802.3af switch. For ease of power management, you can centralize the 802.3af switch and power source, and you can include a UPS (Uninterruptible Power Supply) as a backup. This way your network continues to run even during a temporary power outage. Ubiquiti Compatibility Available in both indoor and outdoor versions, the Instant 802.3af Adapter is compatible with most Ubiquiti PoE devices* using 100 Mbps ports, including: airMAX airVision UniFi mFi Longer Cable Runs High voltage carries power more efficiently (using less current) than low voltage. The Instant 802.3af Adapter enables longer 48V cable runs due to a more efficient power delivery - so your products can get the power they require even when they are located far from the 802.3af switch. ESD/Surge Protection The Instant 802.3af Adapter provides an additional ±15kV of Ethernet isolation for built-in protection that lessens the risk of ESD or surge damage to your device
