Genuine 33W PoE+ Injector for Cisco Meraki MA-INJ-4 MR36 MR44 MR45 MR55

This 33W active PoE+ injector is designed as a compatible replacement for Cisco Meraki MA-INJ-4 power systems. It provides IEEE 802.3at power and Gigabit Ethernet connectivity for select Meraki wireless access points, smart cameras and cellular gateways. Representative compatible devices include MR28, MR36, MR36H, MR44, MR45, MR55 and MR86 access points, along with select MV13, MV73, MG21 and MG21E systems. Compatibility depends on the exact device model and required PoE standard. The injector delivers 55V DC at up to 0.6A and 33W through a shielded single-port active midspan design. It supports network data rates up to 1Gbps and is intended for standards-based IEEE 802.3at PoE+ equipment. Do not use with passive PoE devices or Meraki hardware requiring 802.3bt power above 33W.
