    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).

The small size of mini compressors makes them perfect for mobile or portable refrigeration, cooling electronics, and numerous commercial appliances where weight and space are important.

     

    As a world leader in miniature refrigeration manufacturing, RIGID rotary mini bldc compressors are recognized for their reliability and quality, as well as for their excellent sound reduction and efficiency.

     

    We are continuously developing our rotary compressors, not only to discover new technological advances but also to improve and reach our most successful results when operating them.

     

    The BLDC rotary mini compressor features an optimal pump that operates quietly, while also providing excellent performance. In addition to heat pumps, air conditioners, and commercial cooling applications, this compressor is also well suited for various compact refrigeration applications.

     

    Compared to traditional compressors, RIGID variable speed rotary compressors offer highly efficient and energy-saving features. Unlike a fixed-speed compressor that constantly runs at 100%, the Inverter Rotary Compressor delivers only as much air as it needs for cooling, saving significant amounts of electricity.

     

    Your products will stand out. Your systems will be outstanding!
