An HDR-100W DIN-rail power supply search is a starting point for a door-panel purchase, not a complete order description. The photographed WEHO HDR-100-12 identifies a particular 12 V variant: its front marking states 7.5 A and Max.90Watt. Use those exact fields to build the component line item before comparing it with a card reader or controller requirement. A family name, similar enclosure or nominal voltage alone does not close that comparison.
Turn the family request into a full-model line item
A request such as “one HDR-100 for the door panel” leaves the output variant unspecified. An order record should identify the full model, the intended component position, the supplier document applicable to the order and the equipment revision in which it will be used. Keep the family description as a search or catalog field, rather than letting it replace the model suffix.
The official WEHO HDR-100 page lists separate 12 V, 15 V, 24 V and 48 V model columns. The retained complete sheet also separates those variants. This article uses the actual HDR-100-12 photographs and their matching 12 V column; it does not qualify the other variants by resemblance.
Copy the specimen fields without rounding the family rating
The authentic front label states INPUT:100–240VAC 3.0A, 50/60Hz e OUTPUT:12V DC 7.5A. It separately prints Max.7.5A Max.90Watt. Preserve the original DC symbol and these distinct fields in the component record. Do not change 90 W to 100 W because the series name contains “100,” or assign the generic page’s 24 V feature description to this 12 V specimen.
The physical adjustment marking is 12~13.8V. That is not an observed setting, permission to tune an installed system or a card reader’s allowed input window. The public adjustment table and retained sheet use different percentage descriptions. Keep their attribution rather than selecting a convenient value or treating adjustment as a way to make an unidentified receiver compatible.
Match the purchasing row to an independently identified receiver
For a proposed card-reader or controller position, obtain the exact receiving product’s input specification and applicable configuration. The acceptance row should link that record to the selected supply variant. If the receiver requires a different nominal source, or its allowed input conditions are not documented, keep the comparison open. A 12 V label is not evidence for every access-control device.
Record the receiver’s documented demand and relevant operating conditions without inventing values for a background device. Keep equipment distribution, protection and installation decisions under the responsible design. This article does not calculate a door count, apply a universal current margin or declare the photographed 7.5 A specimen sufficient for an unspecified installation.
Keep function requirements outside the voltage suffix
The component identifier does not establish battery charging, standby runtime, fire-alarm linkage, independent protected door outputs or emergency-release behavior. Those are separate system requirements with their own evidence. Do not add such functions to the order row merely because the intended equipment is a door panel.
The exact source has four upper DC contacts and two lower AC contacts. It does not show a PE conductor terminal or a DC OK relay-contact pair. These visible interface facts help check that the received sample matches the retained source; they do not define a complete door-system wiring scheme. Leave all six contacts unconnected in the proposed review illustrations.
Retain the real mechanical identity with the electrical variant
The complete drawing specifies a 70 mm front width, 90 mm upright height and 54.5 mm body depth. Its separate 58.4 mm extent includes the rear clip. The authentic rear photograph shows molded upper engagement and a lower black plastic release on a TS35 rail. Do not replace that relationship with new feet, a generic metal clip or rail support at the front label plane.
These dimensions identify the component, not a guaranteed enclosure fit. A purchasing row should reference the controlled host drawing and the applicable mounting document without converting either into a universal cover clearance. The label’s environmental and terminal markings remain source-specific; conflicting public and retained auxiliary values are not combined into a new rating.
Make a variant change reopen the affected comparison
The useful procurement deliverable is a row that joins the exact ordered model, its applicable supplier record, the receiver requirement and the disposition of that comparison. Attach the original specimen photographs and complete sheet as supporting evidence. Mark an unidentified receiver or unresolved ordered revision explicitly, rather than replacing it with an assumed compatibility statement.
If purchasing changes the voltage suffix or the equipment team changes the receiver, reopen that comparison. A matching family name or case outline does not preserve a previous electrical decision. Keep earlier evidence intact, identify the changed field and ask for the record that applies to the new configuration.
Send WEHO the full model, intended component position, receiver specification and required ordered-revision documents. This makes an HDR-100W DIN-rail power supply inquiry precise without claiming that a proposed scene proves the door application.
