Sets quantity, ship-to, currency and whether the target budget is per module or for the whole order. Collects deviations in one sheet so headline prices are not compared early.

Din rail dc power supply custom briefs for factory quotes
LinkScope Sourcing 50 is an independent sourcing partner. Share the input source, output voltage, continuous current, DIN-rail width, quantity and US destination so proposed factories answer the same din rail dc power supply custom request.
A family name does not prove the exact model. Ask each respondent for the manufacturer, model and the options included in the price.

Quote scope before any 12 V or 24 V comparison
Buyers often ask for a price before the load and the mechanical envelope are fixed. Use the four rows below as the minimum scope. Leave a cell blank when the project has not decided it, and mark that cell as an open question rather than a factory statement. Ask whether the module sits on a 35 mm TS35 rail, whether hold-up is listed as 20 ms at the named load, and how output current is derated at 50 °C when the input is 115 V instead of 230 V. A 10 A, 24 V line is a different row from a 5 A, 12 V line, and a 48 V plant feed is a different row again. If a safety file is required, request the IEC 62368-1 copy for the quoted model.
| Scope row | What to lock | What stays outside the unit price |
|---|---|---|
| Electrical | Input range, output voltage, current, ripple limit and hold-up at a stated load | Upstream breaker, wire gauge and redundancy diode unless listed |
| Mechanical | TS35 rail, module width in millimetres, depth, ventilation gap and mounting orientation | Cabinet, gland plate and cable management |
| Evidence | Datasheet, wiring drawing and applicable safety file for the exact proposed model | A catalog family photo or a different wattage in the same series |
| Commercial | Quantity, currency, per-unit or whole-order basis, Incoterm and destination | Freight, duties, spares and commissioning if not written in |
The India TEC infrastructure list is a question source for enclosure and power attributes. It is not US compliance evidence. FCC equipment authorization and an applicable NRTL file, when they apply, must be tied to the model that is actually quoted.
Read the procurement brief or open the inquiry options before sending the form.
Who confirms which power question
Network architect
Names the host cabinet, the DC plant or AC feed, and whether downstream switches need a separate Power over Ethernet budget. That load is not the DIN-rail module rating by itself.
Field deployment
Checks rail space, heat rise, service access and whether the DC OK contact must land on an existing alarm pair. Records the installation environment instead of assuming an indoor rack unit.
Quality reviewer
Binds every claim to the exact model. A supplier ISO 9001 certificate describes a quality system. It does not replace the product safety file or a calibration traceability record if output verification is required.
Questions to settle in the opening brief
Custom versus a listed output
State whether 12 V, 24 V or another voltage is mandatory, and the current at the highest expected ambient. A custom winding or connector is a separate lead-time question. Do not treat a catalog photo as proof that the custom build matches it.
New versus refurbished
New equipment may carry a clearer support path. Refurbished equipment may cover a legacy footprint when condition, remaining warranty and test records are explicit. Ask which condition is quoted. Do not mix the two in one price cell.
What the desk will not infer
LinkScope Sourcing 50 does not invent runtime, efficiency or ingress protection. If the cabinet is outdoors, ask for the enclosure rating and the supply derating together. If the site only needs an indoor DIN rail, say so.
Budget without a live quote
An optional target can be an amount or a range, with currency and a per-unit or whole-order basis. High-end, mid-range, budget-friendly or undecided describes the buyer preference. It is not a rating this desk has verified.
Paste the power lines into the brief
There is no file upload on this form. Paste the voltage, current, rail width, quantity, destination and requested timing into the requirements field. Drawings can be discussed after the desk replies.
