The 48V power supply for the communication site is used for broadcast transmission
In 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 operate on -48 VDC power, but why? The short story is that -48 VDC, also known as a positive-ground system, was selected because it provides enough power to support a telecom signal but is safer for the human body while doing telecom activities (such as. The choice of -48V DC for powering telecommunications equipment is a standard practice rooted in a blend of historical precedent and a suite of technical benefits that ensure the robust, efficient, and safe operation of telecommunications networks. This standard is not arbitrary but is the result. Balancing transmission loss and safety: Lower voltages (e., 24V) increase current for the same power (P=UI), leading to higher line losses (Q=I²Rt), overheating, and thicker wiring costs. Utility can be 220V or 380V AC.
