Ericsson ROJR219012/1 MINI-LINK TN Power Supply

The Ericsson ROJR219012/1, marketed as the PFU3 (Power Filter Unit), is a 48V DC power supply and filter module used within the Ericsson MINI-LINK TN (Traffic Node) point-to-point microwave transmission platform. Designed to slot into the AMM 6p subrack, the PFU3 distributes and filters incoming DC power to the active modules housed in the magazine, helping protect sensitive radio and modem electronics from supply-side noise and transients. As a field-replaceable unit, it allows engineers to restore power delivery to a MINI-LINK TN node without disturbing the rest of the installed hardware. This part remains in circulation as a maintenance spare for operators still running legacy MINI-LINK TN microwave backhaul links, where continued support of established point-to-point radio infrastructure is a priority.
