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 PSC_481 to PSC-48124, PSC-48148. Voltage/current aliases stay on this single family page because the index links them to one mechanical file set. Keep the compact supply terminals accessible and separate its input and output wiring corridors in the panel layout. 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 turns incoming electrical power into the voltage and form needed by connected equipment. ### A simple example In a switchgear control panel, an AC-to-DC power supply can provide DC power for relays, controller modules and indication circuits. ### 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: Incoming supply → Power supply → Required control power 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?
