Why Use 48V DC Power in Telecom Systems
• 48V DC powers small cells, remote radio units (RRUs), and distributed antenna systems (DAS). • Efficient for PoE++ (Power over Ethernet) up to 90W (IEEE 802.3bt).
Get QuoteIn a typical telecom dc power system, 48V DC power supports routers, switches, and other critical devices. The 48 volt dc power architecture reduces current. Telecom and wireless networks typically op...
