12V 12038 4.8A PFC1212DE super large wind volume and double ball bearing violent 4-wire fans

:Delta MODEL:PFC1212DESize: 120x120x38MMVoltage: DC12VCurrent: nominal 4.8A (12V current rating 2.98A, Delta fan deficiency is serious, understand stock friends all know, 12038 fan could reach such a high current is this, there is no other comparable to that of his. )Air volume: 252.85CFM (7.16m3/min)Air pressure: 1.412 in H2O (351.7 Pa)Weight: 0.351kgNoise: 66.5 dB (a)Power: 57.6WSpeed control: support motherboard PWM speed controlSpeed: supportInterfaces: Board 4P+ 4D dual power supply connectorCord length: 35cmRpm: 12V under 5500 RPMFan frame: injection molding, glass fiber +VO PBT+30% grade flame retardant;Blades: injection molding, glass fiber +VO PBT+30% grade flame retardant;Fan rotation direction: from the fan blade direction to counterclockwise;Operating temperature:-10 c to + 70 degrees Celsius;Storage temperature:-40 degrees c to + 70 degrees Celsius;Bearings: high-precision ball bearings;Power range: rated power supply plus or minus 15%;Insulation resistance: more than 500 mohm;Withstanding voltage: eign exchange leakage current 0.5mA 500V/1 minutes;Operating life time: when the ambient temperature is 25 degree 80,000 hours.Motherboard PWM speed control cases, adjustment to the 10% following the speed of 1050 rpm, 10%~100% adjust the fan on a level increase of 405 per turn, due to the boards current limiting, so not up to 5500 RPM.Connected directly to the power supply 12V plus or minus 2-pole power, can reach maximum speed.Note: the fan when you very, very violent test, please pay attention to safety, don't let the blade cut fingers, fan speed when turning 11 blades just like 11 sharp cutter the same merciless cut the wind, if the fingers into the cutting area, and ruthlessly cut down ... When the time comes.Strongly recommended use with safety nets.Launch our exclusive support up to 5 a of current Governor can be used with fanHigh quality 12V DC current cooling fan speed Max 5A
