# PS-RDN power-supply redundancy accessory CAD Official Altech PS_RDN STEP, DWG and DXF mechanical set for PS-RDN. Use the power-supply redundancy accessory outline for enclosure, mounting and cable-access coordination; confirm the installed variant and current revision before design use. ## Equipment and file summary Equipment / resource: PS-RDN power-supply redundancy accessory CAD Manufacturer: Altech Resource type: Product family Part number: PS-RDN Listed file formats: STEP, DWG, DXF Listed files: 3 Available previews: Manufacturer source / drawing request Recorded revisions: Confirm the revision with the manufacturer Source checked: 2026-10-29 Download access: Use the official manufacturer source or request the exact drawing ## Related GA references - [Altech PS-RDN power-supply redundancy accessory](https://eloragrid.ai/objects/altech-ps-rdn) - [DIN-rail AC/DC power supply](https://eloragrid.ai/objects/ga-din-rail-ac-dc-power-supply) - [AC UPS cabinet](https://eloragrid.ai/objects/ga-ac-ups-cabinet) Canonical page: https://eloragrid.ai/tools/cad-library/equipment/altech-ps-rdn Manufacturer: Altech Entry type: Product family Part number: PS-RDN Category: Auxiliary power & UPS Formats: STEP, DWG, DXF Market discovery: Global Access: Direct download Official source: https://legacy.altechcorp.com/CAD/1MasterSheet/WebsiteUSE/HTMLWebpages/PowerSupplyMasterSheet.htm Manufacturer evidence: https://legacy.altechcorp.com/CAD/1MasterSheet/WebsiteUSE/HTMLWebpages/PowerSupplyMasterSheet.htm Source checked: 2026-10-29 Follow the official publisher links for the original drawing set. The title block restricts reproduction, so these files and derived previews are not hosted here. Legacy manufacturer download index; confirm current local product availability, electrical ratings and applicable approvals with Altech. The manufacturer index maps drawing group PS_RDN to PS-RDN. This page follows the exact manufacturer drawing group rather than assuming compatibility with neighbouring model numbers. Coordinate the accessory between the independent supply inputs and the common output wiring; verify the actual electrical topology separately. This is a legacy CAD source: confirm current product status, installation clearances and the applicable revision with Altech; the file group alone does not establish electrical ratings, approvals or interchangeability. ## In plain English ### What the equipment does A power-supply redundancy module combines suitable supply paths so the connected load can remain powered if one source is lost, within the designed arrangement. ### A simple example In a substation control panel, it can connect two independent DC supplies to a common supported load. ### What the drawings help you do Use an outline or mounting drawing to plan where the equipment fits and where it attaches. Use a connection drawing to trace its electrical interfaces. A 3D model helps coordinate space; check the manufacturer's installation requirements separately. ### Terms - CAD: Computer-aided design files used to prepare drawings and models. - Revision: The recorded version of a drawing or model. Concept diagram: Independent DC supplies → Redundancy module → Common supported load A simplified explanation of how this item works. It does not show terminal wiring or an operating procedure. - [Altech official source](https://legacy.altechcorp.com/CAD/1MasterSheet/WebsiteUSE/HTMLWebpages/PowerSupplyMasterSheet.htm) ## Which file should I choose?
