Produktbeschreibung

The main board of the outdoor unit of the air conditioner can adjust the operating frequency of the compressor according to the indoor load demand, achieve precise temperature control, and avoid the temperature fluctuation caused by frequent start and stop of the fixed-frequency air conditioner The drive board drives the compressor motor through the power module to achieve stepless speed regulation, and integrates overcurrent, overvoltage, undervoltage, and phase loss protection functions Fan frequency conversion control, supports outdoor fan frequency conversion adjustment, dynamically adjusts the wind speed according to the ambient temperature and system pressure, and improves heat exchange efficiency Switching between cooling modes to achieve seamless switching between cooling and heating modes. In refrigeration mode, the motherboard directs the refrigerant to the outdoor heat exchanger for heat exhaust; In heating mode, the flow direction is changed so that the refrigerant releases heat in the indoor heat exchanger 0011800209T 0011800209B Outdoor Unit Control Board ，Compatible For Haier， Air Conditioner Circuit PCB Conditioning Parts
