Dc power supply industrial fields to close before inquiry
Open items stay openUse this page when a dc power supply industrial request still has blank cells. LinkScope Sourcing 50 will not turn a blank into a factory capability. Finish the cells you know, and mark the rest as questions for every respondent.
Handoff cells for an industrial DC supply
Input
AC range or DC plant voltage, phase, frequency and whether the upstream protection is already chosen. Inrush can be requested as a supplier answer rather than guessed.
Output
Voltage, continuous current, ripple limit and adjustment range. If 12 V and 24 V are both candidates, keep them as two rows so the price is not averaged.
Mechanics
TS35 compatibility, width in millimetres, depth, terminal style and required clearance. Do not substitute a rack unit unless a shelf mount is actually required.
Environment
Ambient, altitude and orientation. Ingress protection applies to the enclosure the buyer names. A bare module rating is a different sentence.
Signals
DC OK contact type, remote on or off, and whether redundancy uses an external diode. Parallel current share is included only when the brief says so.
Evidence
Datasheet revision, wiring drawing and applicable safety file for the exact model. Ask for calibration traceability only if the buyer will verify output on receipt.
Before an alternative is accepted
Check that the alternative keeps the mandatory voltage and current, or that the buyer has written a tolerance. A narrower body can block airflow. A different terminal can change the field kit. A missing alarm contact can leave the cabinet silent. Each of those is a deviation line, not a silent swap.
New and refurbished offers need separate evidence. Refurbished lots should state test coverage and warranty. New lots should state the document revision. Write 12 V or 24 V, current such as 5 A or 10 A, rail width 35 mm, ambient 50 °C, input 115 V or 230 V, and hold-up such as 20 ms. A 48 V feed is a different row. IEC 62368-1 is requested per model. Neither condition is implied by a product photo.
An OEM-coded module and a compatible module are a host-equipment question. That argument does not decide a passive DIN-rail supply. This brief stays on output voltage, current, terminal style, and whether the supply is the source for a downstream load.
Hold-up in milliseconds is not battery runtime. If the site needs minutes of autonomy, the brief should name the battery or UPS and leave the DIN-rail hold-up as its own cell. Impedance and VSWR are radio-path terms. They do not describe this DC output unless a specific filter is being purchased with the module.
Still-open choices
- Is the output voltage fixed, or may the factory offer the nearest standard voltage with a written tolerance?
- Is the width a hard millimetre limit because neighboring breakers are already placed?
- Does acceptance include a sample, a document review only, or incoming measurement?
- Is the optional budget a ceiling for one module or for the whole shipment, and in which currency?
When those four answers exist, move to the inquiry rows or the form. The longer checklist remains the procurement brief.
Hand off the closed cells
Paste the known input, output, width, quantity, destination and timing. Leave a short note on any cell that is still undecided so factories do not invent it.
