schnelle Antwort: A 1000w power supply family name is not enough to approve a purchase. In this WEHO procurement example, the photographed S-1000-24 nameplate reads 24 V and 40 A, while the current published S-1000 specification lists the 24 V version at 0–42 A. Those are separate evidence records, not interchangeable ratings. Multiplying the photographed values gives 960 W; that is arithmetic, not a measured usable-power result. Before releasing an order, ask WEHO to reconcile the supplied hardware revision, nameplate, specification and acceptance conditions in writing. Do not edit the label or assume the larger number applies to the photographed unit.
Start with the evidence, not the series number
For an OEM buyer, a power-supply model name is an identification starting point. The complete ordered configuration, controlled specification and delivered nameplate must describe the same item. A family identifier containing “1000” does not by itself resolve output voltage, current, input range or the conditions under which an output is available.
This article examines a real documentation discrepancy rather than recommending a supply for a particular load. Manufacturer product photographs show a WEHO S-1000-24 unit with a 24 V, 40 A nameplate. When a marketing caption describes another voltage option, that caption does not change the marking on the pictured specimen. For receiving inspection, read the actual full model and rating, then compare them with the ordered configuration. A general illustration or surrounding promotional text cannot identify a different voltage variant on its own.
The current WEHO S-1000 product page and the downloaded S-1000 specification separately list the 24 V column at 0–42 A. We have not established that the photograph and this table represent the same electrical revision. Treating both as one confirmed rating would hide the very issue a buyer needs to resolve.
Keep the photographed rating and published rating separate
The useful procurement record has three columns: evidence, what it says, and what it does not establish.
| Evidence | Observed statement | Limit of that evidence |
|---|---|---|
| Actual photographed nameplate | S-1000-24; output 24 V, 40 A | Does not establish a tested continuous output under the buyer’s conditions |
| Current published S-1000 table | S-1000-24; 24 V, 0–42 A | Does not prove that the photographed 40 A unit belongs to this revision |
| Arithmetic using the photograph | 24 × 40 = 960 W | Not a laboratory measurement, efficiency result or installation allowance |
| Current mechanical drawing | 291 × 132 × 68 mm | Does not reconcile the electrical-rating difference or define installation clearances |
The correct response is not to average 40 A and 42 A, round 960 W to 1000 W, or replace the photo label with the newer table entry. Neither should a purchasing team silently use the lower figure as a universal safety guarantee. A lower printed number does not establish temperature limits, duty, protection behaviour or the suitability of an undocumented revision. The order remains pending until the supplier identifies which evidence applies.
Build a revision-controlled RFQ
When requesting a 1000w power supply, include the full required output voltage and the load information that actually exists. Do not manufacture a current requirement to fit a convenient catalogue image. Provide the normal operating envelope, start-up behaviour if known, duty cycle, ambient conditions and enclosure constraints. Mark missing requirements as unknown so that application engineering can request the appropriate information.
Attach the nameplate photograph and cite the particular specification revision you reviewed. Ask for the complete ordered model, hardware revision or other supplier-controlled configuration identifier, applicable rating table, and an explanation of the 40 A versus 42 A difference. Request confirmation of the input-selection instructions and supplied mechanical drawing. A response that repeats only the series name has not resolved the discrepancy.
Your purchase specification should identify which document wins if a quotation, label and general web page disagree. That hierarchy needs supplier agreement; it should not be invented after delivery. Keep the agreed evidence with the order and receiving record so that a later replacement purchase does not repeat the same ambiguity.
Compare 12 V, 24 V and 48 V as distinct variants
The current S-1000 table lists 12 V at 0–80 A, 24 V at 0–42 A, and 48 V at 0–21 A. These are published family entries, not observations of three photographed specimens. Only the 24 V, 40 A marking is visible on the source unit used here. No image in this article proves a 48 V specimen’s identity.
Voltage selection must follow the receiving equipment and system design, not the attractive size of a current number. A 12 V system, a 24 V system and a 48 V system are not made interchangeable by sharing a family name. Multiplying published column values also does not establish that every variant delivers the same usable power in every installation.
A separate programmable family such as SE-1000 introduces different input and control considerations. Its availability is not permission to substitute it without checking the ordered variant, source documentation and interface requirements. This example therefore remains a S-1000-24 evidence review, not an endorsement of an alternate family.
Separate receiving inspection from an energized acceptance test
The application illustrations represent two non-energized procurement activities: an OEM request-for-quotation comparison desk and a distributor receiving/quarantine station. They do not depict a proven electrical application, an installed machine power source, or a measured load test. The output studs remain unconnected. A loose reference rail in the scene is a scale cue, not a mounting accessory for this enclosure.
At receiving, compare the delivered full-model marking, output polarity identification, enclosure configuration, cooling arrangement and document revision with the order. Record discrepancies before releasing the unit into stock. If the serial or batch identification is relevant, preserve it in the receiving record rather than inferring a manufacturing date from an unfamiliar code.
Electrical acceptance is a separate controlled activity performed by qualified personnel using the applicable supplier procedure and appropriately rated equipment. This article does not provide wiring instructions, mains-selection instructions or a test-load prescription for the unresolved specimen. Do not energize an uncertain configuration simply to see which current figure appears plausible.
Check mechanical information without overstating it
The current S-1000 mechanical drawing shows a 291 mm length, 132 mm width and 68 mm height. Keep the axes explicit when reviewing an equipment envelope. The source photograph shows a long metal enclosure, cooling fan and output studs at one end, with the input terminals at the other end. It is not a DIN-rail power supply merely because a rail happens to be available in the workshop.
Exterior dimensions do not define the required ventilation space, terminal access, cable bend room or guarding arrangement. Nor does a matching enclosure prove that two electrical revisions have identical performance. A useful mechanical check records the drawing identifier and the actual unit’s configuration, then asks for any installation requirements absent from the evidence set.
Define a clear purchasing release gate
A 1000w power supply purchase can move forward when the supplier’s response connects the quotation, exact ordered configuration, applicable specification and expected delivered label. If the photographs are legacy marketing material, have that limitation stated explicitly and obtain current controlled evidence. If the table describes a different revision, obtain the document applicable to the ordered unit instead of combining the two.
For replacement stock, keep unverified units separate from approved stock. This is a documentation disposition, not a finding that every photographed unit is defective. The issue established here is a mismatch between evidence records; its engineering explanation has not been independently confirmed. Record that distinction so purchasing, quality and maintenance teams do not turn uncertainty into either an unsupported approval or an unsupported failure allegation.
Wichtige Erkenntnisse
- Identify the product from its full actual marking, not a general marketing caption.
- The photographed S-1000-24 says 24 V, 40 A; the current table separately says 24 V, 0–42 A.
- 960 W is arithmetic from the photographed values, not a tested usable-power promise.
- Matching exterior dimensions do not reconcile an electrical revision discrepancy.
- Release purchasing only after the supplier confirms a consistent ordered-document set.
Abschluss
The practical question behind a 1000w power supply order is not whether “1000” appears in a title. It is whether the evidence consistently identifies what will be supplied and under which conditions it may be used. Preserve the real label, state the current published specification separately, and resolve the revision before recommending a load or releasing stock. For this photographed S-1000-24, the 40 A versus 42 A difference remains a procurement stop until WEHO supplies the applicable revision confirmation.
Häufig gestellte Fragen
Does the S-1000-24 photograph prove a 1000 W output?
No. The photographed label says24 V40 A; multiplying those values gives960 W. That is arithmetic, not a measured usable-power result.
Why does the current specification list42 A?
The current published S-1000 table lists24 V0–42 A, while the photographed nameplate says40 A. The revision relationship is unconfirmed and must be resolved by WEHO before procurement release.
Can a marketing caption identify a different voltage variant?
No. The physical label in this manufacturer photograph says S-1000-24 and 24 V 40 A. A general marketing caption cannot replace that actual marking.
Do matching291×132×68 mm dimensions settle the current discrepancy?
No. Mechanical agreement does not establish an electrical revision or continuous output rating.
Are the illustrated workstations connected applications?
No. They show isolated, non-energized quotation and receiving checks. They are not evidence of load compatibility, performance testing or installation approval.
