Telecom and wireless networks typically operate on –48 V DC power, but why? 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.
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.
A power supply with a capacity of 100 W to 350 W was sufficient to cover many applications. Forward converters were a good choice and have been employed for years in telecom BBUs and RRUs. With the growing demand for mobile data, new markets and applications continue to emerge.
Our standardized photovoltaic container and energy storage products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
