150W - 300W Inverter Card

BLDC Motor Drives
BLDC Motor Drive 150W - 300W

The inverter compressor that can operate at variable speeds because it is operated with Inverter Drive. Unlike the standard single-speed compressor, which is either off or operating at full speed (typically about 3,600rpm), the digital inverter compressor is almost always on, but can operate at different speeds, Using the inverter refrigerator drive– from 1,100 to 4,300rpm. This ensures high efficiency and consistent temperature inside the refrigerator. It also results in significant cost savings, a reduced carbon footprint, less noise and a longer lifespan for the compressor. The digital inverter compressor is one of the most important innovations in the history of refrigerators and food preservation and Samsung has led the way.
