The HF-125 is our new high frequency controller that operates at 7,000 Hz.   This is the controller you want if you are going to power a BRUSHLESS fan motor.   It will also power any brush type motor.   It will prevent fan buzz found in some Asian fans.     It has soft start and the cool down timer.   We fixed the fail safe problem that now puts this controller to 100 percent RPM when pin 7 is grounded.   This controller can run one  or more fans.   Two large 1/4 inch brass studs for fan and ground power.    The top and bottom of the HF-125 is made from 1/8 inch aluminum plate for a heavy duty heat sink.   The top case in powder coated.
