Question A Power Adaptor to Replace a PoE Switch for an Access Point

[mblue.hblue]

Access Point : Ruijie RG-AP720-L

can a power adaptor be used to power this access point?
its poe switch was broken, i want the cheapest one
i tested some power adaptors , they couldn't power the access point normally, because the signal couldn't detected.

i need your help to send some links to buy the specific power adaptor for this access point
thank you so much

There are a lot of different versions that match your generic part number.

This document -- https://www.ruijie.com/en-global/resources/preview/RG-AP720-L-Datasheet/ says that an 802.3af (standard POE) is all that is required.
There are lots of Ubiquiti POE injectors on E-Bay. This one for example -- https://www.ebay.com/itm/185905007970 The key thing is to be sure it is a 48V "af" device. NOT a 24V passive.

Power Supply and Consumption	RG-AP720-L
Input power supply	The AP supports the following two power supply modes: ● 12 V DC/1.5 A power input over DC connector: The DC connector accepts 2.1 mm/5.5 mm center-positive circular plug. A DC power adapter needs to be purchased separately. ● PoE input over LAN 1: The power source equipment (PSE) complies with IEEE 802.3af standard (PoE). Note: ● If both DC power and PoE are available, DC power is preferred.

So you either use 12V / 1.2A DC power adapter with 2.1 mm/5.5 mm center-positive circular plug or

a 802.3af PoE Injector
