PFU-B 225 V2.2
Description

The Tellabs PFU-B 225 V2.2 is a power feed unit designed for telecommunication chassis and modular network systems. It provides regulated DC power distribution to backplane-connected modules such as control cards, interface units, and processing boards within carrier-grade infrastructure. The unit is intended to support stable and continuous operation of system equipment in high-availability network environments.

The PFU-B 225 V2.2 operates as part of a modular power subsystem, supplying DC voltage through the system backplane and ensuring consistent power delivery across installed modules. It is typically used in redundant power configurations, allowing multiple units to share load and provide system resilience in case of a single power module failure.



The module integrates protection functions including overvoltage, overcurrent, short-circuit, and thermal protection to safeguard both the power unit and connected equipment. Front-panel indicators provide operational status and alarm signaling for monitoring and maintenance purposes.



Designed for installation in Tellabs subrack or chassis systems, the PFU-B 225 V2.2 is engineered for continuous operation in telecommunications environments. It is resistant to vibration, temperature variations, and electromagnetic interference, making it suitable for carrier-class network infrastructure requiring reliable and redundant DC power distribution.
