# Redundant power-supply decoupling module Canonical URL: https://eloragrid.ai/symbols/redundant-power-supply-decoupling-module Publisher: Elora Grid Updated: 2026-10-13 Lookup label: PSU RED Drawing use: SLD, Schematic Reference families: Manufacturer A redundancy module decouples documented power-supply inputs before they feed a common load circuit. ## What it represents A redundancy module decouples documented power-supply inputs before they feed a common load circuit. The drawing shows each source input and the combined output so the redundancy arrangement is reviewable. ## How to read it - Check each source's ability to supply the required load under the defined operating condition. - The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation. ## Information to show or reference - Show both source inputs - Identify common output - Reference monitoring/decoupling behaviour ## Important distinction Two parallel supplies alone do not establish the same decoupling function as a redundancy module. ## Facts - Drawing role: Energy conversion - Representation scope: Functional concept; not an official standard graphic or a product footprint - Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name. ## Public references - [AC/DC power supplies and DC/DC converters](https://www.phoenixcontact.com/en-gb/products/power-supplies/power-supplies-with-maximum-functionality) — Phoenix Contact. Public documentation of this equipment function or named vendor variant; the illustration is independently authored and is not the source graphic. ## Graphic scope Independent original educational concept illustration by Elora Grid.
