Base station power supply and BBU

4 FAQs about Base station power supply and BBU

What is the difference between a PSU and a BBU?

It mostly uses lead-acid batteries to store power and is a widely used power backup mechanism. In contrast, FSP's PSU plus BBU conceptually integrates UPS functionality into the power supply unit itself. It is a power solution that combines both power supply and battery backup mechanisms.

What is a battery backup unit (BBU) & a power supply unit (PSU)?

The pressure to meet this demand is most apparent in the design of Battery Backup Units (BBUs) and Power Supply Units (PSUs), where connectors must support high currents, dense packaging, hot-swap functionality, and low resistance, all while maintaining mechanical robustness and signal integrity.

What is a BBU & how does it work?

BBUs are stacked up to provide backup power to the UPS. These are monitored by the Power Monitoring Interface (PMI), which is connected to a power shelf comprising Power Supply Units (PSUs).

How does a PSU supply power to a server?

The PSUs then supply power to the servers and other data center equipment by sourcing power from the mains during normal operation or from the backup battery units (BBUs) during a power outage. The power is channeled through busbars to individual Power Distribution Units (PDUs) that source power to each server.
