Description
Sunon VF60384BX-1000U-Q9H (also known as VF60384BX1000UQ9H) is an ultra-high-speed 48 VDC brushless tubeaxial cooling fan housed in a compact 60 × 60 × 38 mm (2.36 × 2.36 × 1.50 in) square form factor. Engineered for high-impedance thermal loads, it delivers an impressive nominal airflow of 67.8 CFM (115.2 m³/h) and static back pressure of 4.84 in H₂O (1,205.6 Pa) at 22,800 RPM with a rated power draw of 22.08 W. The mechanical assembly utilizes a precision dual ball bearing system paired with a UL 94V-0 flame-retardant PBT frame and PPE impeller. Integrated smart features include a 25 kHz PWM speed control interface, an open-collector rotation detector (RD) lock sensor output, and electronic auto-restart with reverse polarity protection.
Key Features
- High-Static Aerodynamic Profile: Generates 4.84 in H₂O (1,205.6 Pa) back pressure to overcome extremely dense chassis flow resistance.
- Precision Dual Ball Bearings: Ensures robust rotational stability with an expected service life exceeding 70,000 hours at 40°C.
- Intelligent Dynamic Speed Control: Accepts 22 kHz to 28 kHz PWM inputs with linear duty cycle regulation from 0 to 22,800 RPM.
- Embedded Rotation Detector: Features an active-low RD lock sensor output circuit to signal stall conditions immediately to system management.
- Comprehensive Motor Protection: Built with automatic restart circuitry and reverse polarity protection to safeguard against electrical installation faults.
