(Open Circuit) When the control lead wire is open, speed is same as one at 100% PWM duty cycle. This fan speed should be controlled by PWM input signal of either TTL input or open collector, drain input. （VCE） 70 70×70×38mm GA type 80×80×80mm ■ PWM Duty - Speed Characteristics Example 9GA0712P1G001(0011) 9GA0712P1H001(0011) 2,000 0 4,000 6,000 8,000 10,000 12,000 14,000 16,000 18,000 100 0 100 0 16,500min-1 12,000min-1 2,000 0 4,000 6,000 8,000 10,000 12,000 14,000 Voltage：DC12V PWM Frequency：25kHz Voltage：DC12V PWM Frequency：25kHz PWM Duty Cycle（%） PWM Duty Cycle（%） ■ Air Flow - Static Pressure Characteristics ・ PWM Duty Cycle ・ Operating Voltage Range → Air flow → Air flow PWM Duty Cycle 100％ → Air flow PWM Duty Cycle 100％ → Air flow (CFM) (m3/min) (CFM) (m3/min) （Pa） DC 12V （inch H2O） （Pa） （inch H2O） 9GA0712P1H001(0011) 9GA0712P1H001(0011) （Pa） DC 12V （inch H2O） 9GA0712P1G001(0011) （Pa） （inch H2O） 9GA0712P1G001(0011) (CFM) (m3/min) (CFM) (m3/min) 0 3 0 0.5 20 0 200 1 2 40 60 80 100 400 600 800 1,000 1.0 1.5 2.0 2.5 3.0 3.5 4.0 0 3 0 0.5 20 0 200 1 2 40 60 80 100 400 600 800 1,000 1.0 1.5 2.0 2.5 3.0 3.5 4.0 0 0 0.5 20 0 100 0.5 1.0 1.5 2.0 2.5 40 60 80 200 300 400 500 600 1.0 1.5 2.0 0 0 0.5 20 0 100 0.5 1.0 1.5 2.0 2.5 40 60 80 200 300 400 500 600 1.0 1.5 2.0 0% PWM Duty Cycle 100% 0% 50% 13.2V 12V 10.8V 13.2V 12V 10.8V 50% PWM Duty Cycle 100% |
