12V/24V/48V BLDC Fan Solution
The DC fan modules are available in single-phase and three-phase. Power supply ranges from 12V to 48V with power wattage less than 40W. The BLDC fan modules are designed as parameter adjustible and suitable for BLDC fan size from 4025, 4028, 6038, 8025, 8038, 8080 to 12038 or larger. These ready to tune modules are ready for server, telecomm or high end graphic card applications. It supports either PWM or VSP input command, open-loop or closed-loop curve. Adjusting control curves, quick start, soft start, brake, leading angle, and soft switching parameters for best noise driving performance. The system protection is completed with the adjustable over current, over voltage and under voltage protection.
