Fan Overheat Protection Devices

Post by om_tech_support_JT » Fri Apr 23, 2010 3:28 pm

Q: Are fans, like motors, equipped with overheat protection devices?

A: All AC fans in the ORIX Fan line that meet UL, CSA and EN/IEC standards either have motors with impedance protection or are equipped with a thermal protector. The DC fan includes a current detection function in the drive circuit. In the case of abnormalities, the fan input current is controlled to prevent an increase in temperature and thus guard against burning out the fan motor.
