What happens if a PWM device connected to D5 NEXT try to draw more than 25W?

D5 NEXT specification tells that it can provide 25W power through its PWM port.


What happens if I connect a device potentially can draw more than 25W?

For instance, I may connect a group of PWM fans with total maximum power of 30W.
Or, I may connect a PWM pump whose maximum power is 30W.

Is it just slow down the device with low RPM? Or maybe something bad could happen?

The fan output is broken against.
This can happen even with less power if the fans have a high startup current.
This value is to be understood as an absolute maximum and must never be exceeded.

Understood, thank you for your clear answer!
