Delta EFB0405HHD-R00 5V 0.45A Three-Lead Fan

The Delta EFB0405HHD label shows the -R00 option, DC 5V and 0.45A. Three red, black and white leads terminate in a white connector. The standard-model approval has a 0.30A input and 0.45A maximum, but the complete R00 connector and signal specification were not established.

Does the third wire guarantee a tachometer output?

The lead count alone does not identify the signal. Confirm the R00 monitoring function, connector positions and mechanical drawing before connecting the fan to a controller.
