Abstract

A system for distributing power to a plurality of electronic modules housed within an electronics cabinet includes an electronics cabinet and at least one power filter mounted to the electronics cabinet. At least one electronic module is housed within the electronics cabinet. A first bus bar is positioned within the electronics cabinet for receiving at least one power input cable. A second bus bar is positioned within the electronics cabinet and is electrically connected to the first bus bar and to the power filter. The second bus bar routes input power from the first bus bar to the power filter and routes filtered power to the at least one electronic module.
