    Drive Board & Display Panel

     

    It is easy to integrate the drive board (PCB) & display panel into your application if you need sophisticated functions, or want to control by your software.

     

    The motor drive board is a variable speed drive. This allows the cooling capacity of the system to be adjusted by increasing or decreasing the compressor speed. The compressor drive board utilizes a user-supplied 0-5 VDC analog signal to set the compressor speed. The firmware has a minimum speed of 2,000 RPM (0.7 VDC or lower) and a maximum speed of 6,000 RPM (4.5 VDC or higher).

    The voltage to RPM relationship is linear between 0.7 and 4.5 V so the following equation can be used: S = 1132×V+1408.

     
    * Where S is compressor speed (RPM) and V is the control voltage (VDC).
