Through MCU, power management, drive, storage, operational amplifier, communication and other circuits, drive BLDC fans with power less than 1 kW. With PFC control, compatible with input voltages of 120VAC and 220VAC. The fan drive uses 180° sine wave FOC control algorithm, ensuring smooth speed, with a rated speed of up to 20,000 rpm. It has comprehensive protection functions to effectively protect itself and the fan in case of malfunctions.
Through MCU, storage, communication, power management, voltage regulator and other circuits, set fan functions through the operating interface, view motor information through the display interface, and control the speed of multiple BLDC fans through the RS485 group control interface. The fan drive uses 180° sine wave FOC control algorithm, ensuring smooth speed, and has overvoltage, undervoltage, and overheat protection functions.
Through MCU, high-efficiency power management circuit, DC water pump drive circuit, water pump current sampling circuit, heating tube drive circuit, realize functions such as instant heating control after purifying tap water, automatic water supply control, quantitative water output control, TDS water quality detection, voice recognition, and meet low standby power requirements.
