Will a 48v PoE Injection adapter fry my 12v EnGenius AP
Will a 48v PoE Injection adapter fry my 12v EnGenius AP
I have a EnGenius EAP-1250 Access Point that I would like to power using PoE. The AP states its power specs are DC IN, 12V/1A and 802.3af/at PoE Input, yet the PoE Injector adapter that I want to buy states its power specs are 48v 65W. So, will either of these devices regulate the voltage so that my EnGenius AP is not fried or do I need to find a PoE Injector adapter that is rated for 12v? I'm worried because 2 or 3 people in the reviews said the following: " Obviously you wouldn't want to use this 48v device on something like a 5v, 12v or 24v POE device or you will fry it! " That concerns me, because I thought 48v was the 802.3af standard, and as long as both devices adhere to this standard, then the voltage will be regulated automatically. Can someone please confirm this? I tried to chat with someone at EnGenius, but it keeps saying that no one is available, and they do not have a phone number. This is the item I'm looking at. It's cheap, but it's all I need: iCreatin 4-Ports Passive Power over Ethernet PoE injector Adapter with 48V65W Power supply for 4 IP Camera, VOIP phones or Access Points and more https://www.amazon.com/iCreatin-4-P..._n...7306160011
I've been researching PoE switches, adapters, datasheets, and vendors for the last hour and a half. Checking 802.3 standards online, it seems the switch should work if it supports 802.3af or 802.3at. But the injector I saw looks questionable, and the APs cost around $150—so I’d skip that. Opt for this one instead; it’s pricier but safer for the APs and your home.
Thank you for your feedback. Your perspective matches what I experienced initially, but after researching extensively, I now have a clearer grasp. I also think the current option seems a bit uncertain, so I might consider a more reliable alternative, like the one you recommended.
