802.3at multigigabit PoE injector for compatible Cisco Meraki MR53, MR53E and MR84 wireless access points. The injector is based on the MA-INJ-5 platform and provides 55V DC output at up to 0.6A while carrying Ethernet data and PoE power over a single network connection. Key replacement references include MA-INJ-5, MA-INJ-5-US and Microsemi PD-9001-10GR/AC. This listing is intentionally focused on the older 802.3at MA-INJ-5 platform. It should not be confused with newer Meraki injector revisions that use different 802.3bt power specifications.
