Gentle Typhoon AP-15 1850rpm PWM Capable with 4pin Adapter?

[MattMan657]

Hey all,

I have a few GT AP15 1850rpms lying around and the boxes show that they're the 3pin models, but also include a 4pin cable. Does the 4pin cable enable them to function as PWM?

Full product code is D1225C12B5AP-15

Thanks!

The high speed models have a fourth "PWM" pad on their PCB to convert them into PWM by soldering another wire. However, the lower speed models like your 1850s only have 3 pads (12v, GND, RPM) so no PWM mods for those.
