Current: Nominal 4.8A (12V rated current 2.98A )
Air volume: 252.85 CFM ( 7.16 m3/min)
Wind pressure: 1.412 in H2O ( 351.7
Pa) Weight: 0.351 kg
Noise: 66.5 dB (A)
Power: 57.6W
Speed Regulation: Support PWM Speed Regulation of Main Board
Speed measurement: support
Interface: Motherboard 4P (default) /Power Big 4D Dual Power Supply Interface (advance mail message)
Line length: 35cm
Turn: 5500 RPM at 12V
Fan frame: injection molding once, PBT + 30% glass fiber + VO class flame retardant;
Wind blade: one-time injection molding, PBT + 30% glass fiber + VO grade flame retardant;
Fan rotation direction: from the direction of the fan blade for counterclockwise;
Operating temperature: - 10 degrees Celsius to + 70 degrees Celsius;
Storage temperature: - 40 degrees Celsius to + 70 degrees Celsius;
Bearing: high precision ball bearing;
Power supply range: positive or negative 15% of rated power supply;
Insulation resistance: greater than 500 megaohms;
Voltage withstanding: leakage current 0.5 mA 500V/1 minute;
Working life: 80, 000 hours at 25 degrees. In the case of the main board PWM speed regulation, the speed below 10% is 1050 revolutions, and the fan of 10%~100% is increased by 405 revolutions per level of regulation. Due to the current limitation of the main board, the speed can not reach 5500 revolutions. Direct power supply 12V positive and negative 2 pole power supply, can achieve maximum speed.
Note: Fans are very, very violent, please pay attention to safety during testing. Don't cut your finger by the blade. When the fan rotates at high speed, 11 blades cut the wind like 11 sharp knives. If the finger enters the cutting range, it will cut it relentlessly. That's the time. It is strongly recommended to use protective nets.
