Power Over Ethernet POE48xx-y Series


The POE4820-A, POE4820-P and POE4848-C are mains powered 48V dc power supplies with battery back-up capability. Providing 48V dc at either 20W or 48W (model dependent) they are ideal for powering PoE Power Sourcing Equipment (PSE) such as dc powered injectors, midspans or switches. POE4820-P is housed in an IP68 rated enclosure for harsh environments. Battery back-up is provided by either a 12V 3.2Ah, 7Ah or 17Ah VRLA battery (product specific), utilising the industry standard battery to supply 48V dc.

• POE4820-A/-P provides 48V dc at 0.4A (max)

• POE4848-C provides 48V dc at 1.0A (max)

• Can be used to power either PoE (802.3af) or PoE+ (802.3at) dc powered PSE devices

• Ideal for CCTV and access control applications
