What does the manufacturer separate?
Schneider Electric's technical specifications for its 10 kVA 3:1 Easy UPS 3S Pro list input power factor, output power factor, load power factor and load crest factor separately. Its crest-factor entry is expressed as a ratio, while the input power-factor entry also carries a load condition.
Those separate rows support keeping separate quantities and conditions in the drawing schedule. They are not universal UPS ratings. Critical Power Drafting is independent and is not affiliated with Schneider Electric; use the approved selected-model submittal.

How should a source-to-drawing cross-check work?
Copy the full source label before transferring a value. Input behavior, a rated output basis and an allowed load condition are not interchangeable just because they concern the same UPS.
| Source row | Record separately | Do not substitute |
|---|---|---|
| Input power factor | Value and operating load | Load crest factor |
| Output power factor | Rated output basis | Input performance |
| Load power factor | Supported range and conditions | A single rating label |
| Load crest factor | Ratio and applicable limits | Power-factor value |
| Equipment boundary | Model, supply and revision | Another UPS variant |
What would a transfer error look like?
Illustrative example. A fictional schedule gives a UPS one blank factor field. A drafter enters a quoted crest-factor ratio of 3:1, while the reviewer assumes the field describes load power factor. Both people can point to a source row, but they are answering different questions.
Resolve the ambiguity by naming the requested quantity and preserving the source conditions. Do not divide the ratio, interpret it as 300 percent power factor or use it to calculate kW. Missing input and load data remain open technical inputs.
What belongs in the issue record?
Record the conflicting source label, drawing field, applicable operating case and responsible engineer's decision. Check all schedules that reuse the ambiguous factor field, then retain the source revision with the corrected entry.
This is a transcription check. It does not establish load compatibility, select protective devices or approve UPS capacity. Engineering sign-off is performed only by the registered engineer on the job.
Common questions
What else should the bid team know?
Is a crest-factor ratio a power factor?
No. Keep the manufacturer quantities under their own labels.
Can another UPS model supply a missing value?
No. Obtain the approved selected-model information.
Does a complete schedule prove compatibility?
No. The responsible engineer must assess the actual load and equipment.
