Can a –48 volt DC power a PA?However, the –48 V DC must first be efficiently converted to a positive intermediate bus voltage before it can be boosted to power the PA or stepped down to a positive workable supply for the digital baseband units (BBU). A power supply with a capacity of 100 W to 350 W was sufficient to cover many applications.
Why is a –48 V DC a positive ground system?The short story is that –48 V DC, 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.
What is a scalable –48 V DC Pol solution?This article presents a scalable and stackable –48 V DC PoL solution that will address the high density power usage situations created by these high density networks from the tremendous growth in network traffic. Telecom and wireless network systems typically operate on –48 V DC power.
What is negative 48 volt DC?Negative 48 V DC is still the standard in communications facilities serving up both wired and wireless services as it is perceived to cause less (or at least inhibit galvanic) corrosion in metal than positive voltages.
