General Description
The ACSD050-120051 is a Solid State AC Motor Control.  It is designed for various mounting positions.  
It operates with 115 VAC, 50/60 Hz and is capable of 5.0 Amps RMS @ 50°C.  With proper heatsinking, 
higher operating currents can be obtained.  The ACSD050-120051 provides infi nitely variable speed motor 
control for Shaded Pole, Permanent Split Capacitor Motor, Capacitor Run Motor, and Universal Motors.  
The ACSD050-120051 variable speed motor control provides a basic form of speed control and a switch 
input for motor RUN/STOP.  Applications include range hoods, vibrators, humidifi ers, fi replace  blowers, 
fans, laminar fl ow hoods, heat tunnels and stirrers.

How it Works
The ACSD050-120051 is a simple phase control driver which varies the effective RMS line voltage.  The 
torque developed by an induction motor is proportional to the square of the applied voltage.  If the load has 
a torque-speed characteristic such as shown in Figure 1, then the speed of the motor can be controlled 
over a small range by varying the line voltage.  This curve is not to be confused with a universal type mo-
tor curve, as a universal motor can be used with this driver as well.  Otherwise, a different type of motor 
and control application needs to be visited.
Input Pin Descriptions
The ACSD050-120051 is a simple AC motor speed control.  The speed is adjusted by the onboard po-
tentiometer.  Pin I1 and I2 needs to be connected together via Switch or a simple jumper if the feature is 
not being used.  Input Pin C1 and C2 is the connection for a running/start Capacitor.  Pin MC is where the 
common point of the Main and Auxiliary winding of a AC Induction or AC Reversible motor.  Pin M1 and 
M2 is where the Main and Auxiliary windings connect to respectively.
Switching Directions
Switching Directions can be either be done by switches or by simply reversing the main and auxiliary 
windings from one pin to the other.

Hook-Up Drawings
For other motor connections, such as a universal motor or other 2 wire connections, one can connect 
the leads to the MC and M1 quick disconnects.  If doing so, please cover the M2, C1, C2, connections 
so shock or injury will not occur.
Power Supply Recommendation
The ACSD050-120051 must be powered by 120 VAC 50/60Hz.
Warning: When using a higher current motor, the driver may overheat and burnup.  Use additional 
airfl ow and heatsinking to keep motor and driver temperature under 80°C.
