  • Why are 48V DC power supplies used in communication systems

    Why are 48V DC power supplies used in communication systems

    The -48V DC standard ensures a consistent power supply that is crucial for the uninterrupted operation of sensitive telecommunications equipment, thereby maintaining the integrity of communication services. This standard is not arbitrary but is the result. 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. In communication infrastructure—whether it is the RRU of a 5G base station, servers in data centers, or switches in outdoor cabinets— DC 48V is almost universally adopted as the standard supply voltage. Efficiency & Reliability: AC systems. Telecom networks choose 48v dc because it offers a safe extra-low voltage, efficient power delivery, and reliable backup. • Efficient for PoE++ (Power over Ethernet) up to 90W (IEEE 802. 2 Energy Efficiency • 48V DC systems avoid AC-DC conversion losses in rectifiers.
