Description
The Protechnic MGT3812HB-W28 is a high-performance 12 VDC DC Axial Fan with dimensions of 38 x 38 x 28 mm, engineered for compact high-density electronic cooling. Constructed with a thermoplastic housing (UL 94V-0), thermoplastic impeller, and maintenance-free dual ball bearings, it has a weight of 43 g. Driven by a brushless DC motor, it operates at a nominal voltage of 12 VDC with a rated current of 0.28 A (actual current 0.23 A) and a power consumption of 3.36 W (actual power 2.76 W). Operating at a nominal speed of 11000 RPM, it produces a max. air flow of 15.05 CFM (25.56 m³/h / 0.43 m³/min) and a max. static pressure of 19.50 mmH₂O (191.30 Pa / 0.77 inH₂O) with a noise level of 50.0 dBA. Featuring a 4-wire connection with PWM speed control input and FG speed monitoring tachometer signal output, it is designed for an operating temperature range of -10 to +70 °C and a lifetime of 40,000 hours at 60 °C, with CE, TUV, and UL agency approvals.
