Control of the Speed of Ceiling Fan Running of UPS

Nouman Abid Chuhan
Hello


It is observed that when main supply is failed and home appliances diverted on stand by supply i.e. UPS, for example, the speed of the ceiling Fan becomes un-controlled and it rotates at its maximum speed.  Conventional Dimmers consisting on Diac Triac Set can not control the speed of the Ceiling Fans while running on the UPS, causes, heating air to users.  Majority of the UPSs do not generate a true Sine Wave, is it the real problem.   While being facing this non-sinusoidal constraint, how can we overcome this.


Can someone suggest any cost effective solution please.  Thank you.

    Hello Clive


    Thank you for your reply.


    Suppose, i have such a UPS which have not providing a pure sine wave and i am using a coventional Dimmer too.  Is any special kind of Dimmer or related electronic device available in the market by which i could overcome the subject issue.


    Other given solutions are costly.  Thank you.
