FAQ Section

Q: Can I use this 3A adapter on a device that only requires 48V 1.5A?
A: Yes, absolutely. Your device will only draw the amperage it needs. Using a 3A adapter for a 1.5A device is perfectly safe and often means the adapter will run cooler and last longer.

Q: Is the AC wall plug included in the box?
A: No, this listing is for the adapter block only. You can use your existing standard 3-prong PC power cable or purchase one directly from our store here.

Q: What type of devices typically use a 48V adapter?
A: 48V adapters are most commonly used for Power over Ethernet (PoE) network switches, advanced CCTV/IP camera systems, specialized LED lighting controllers, and some audio amplifiers. Always verify your device's voltage requirement before use.
