ebm-papst 4314S Data Sheet

A

4314 S DC Axial Fan

xial fan with high air flow and minimum noise
level. The DC drive employs an electronically
commutated external rotor motor with high
efficiency. Drive electronics is completely in­tegrated into the fan hub. The air flow and
noise level can be controlled by varying the
supply voltage range.

Features

• Electronical protection against locked

rotor

• Electronical protection against reverse

polarity

• Integrated speed sensor

• Extremely low EMI.
