Configuration and qualification table
| Verification layer | Current reference | Production-release requirement |
|---|---|---|
| Base performance reference | SXD12038H | 5000RPM, 240.1CFM, 34.6mmH2O, 65dBA catalog values |
| PWM command interface | Configuration-specific | Approve voltage level, frequency, duty range, stop/minimum behavior and grounding |
| Feedback and fail-safe | Not inferred | Define FG/RD availability, pull-up, alarm threshold, lost-command response and restart logic |
Engineering release rule: Catalog and current-page values are reference data under their stated conditions. The approved drawing, complete model suffix, controlled datasheet, sample label and validated equipment test govern the final purchasable configuration.
Model-specific engineering FAQ
Which PWM electrical values must be approved before this 12V fan is connected?
Approve PWM input level, frequency, duty range, controller ground, pull-up requirements, minimum-speed or stop behavior and startup response; connector shape does not define these values.
Is the catalog 240.1CFM value available at every PWM duty cycle?
No. It is the H-grade full-output free-air reference. PWM changes speed and the equipment resistance sets delivered airflow, so validate the complete control range.
How should a lost PWM command be handled in a server controller?
Define the required fallback speed, alarm state, thermal shutdown and restart logic, then test the actual host controller with the approved fan configuration.
What is the difference between PWM command and FG feedback?
PWM is a host command input. FG, if included by the approved configuration, is a rotational feedback output. Their pins, levels and functions must not be interchanged.
