This unit handles power distribution and filtering functions, ensuring clean, regulated power delivery to critical radio and baseband equipment within the base station cabinet.

The PDFU-B is typically deployed as part of Nokia’s Flexi or similar base station platforms, where reliable power management is essential for continuous network operation. It integrates into the base station’s power architecture to distribute DC power while providing filtering to protect sensitive electronics from power anomalies.
