(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) ○ ＋ ○ － Rated Voltage 12 V Fan VCE＝＋15 V MAX. Ic＝10 mA MAX.［VOL＝VCE (SAT) ＝0.6 V MAX.］ Rated Voltage 48 V Fan VCE＝＋60 V MAX. Ic＝10 mA MAX.［VOL＝VCE (SAT) ＝0.6 V MAX.］ 92 92×92×38mm 9HV type 80×80×80mm ■ PWM Duty - Speed Characteristics Example Voltage：DC 12 V PWM Frequency：25 kHz Voltage：DC 48 V PWM Frequency：25 kHz PWM Duty Cycle (%) PWM Duty Cycle (%) 9HV0912P1G001 100 0 14,900 min-1 0 2,000 4,000 10,000 6,000 8,000 12,000 14,000 16,000 9HV0948P1G001 100 0 14,900 min-1 0 2,000 4,000 10,000 6,000 8,000 12,000 14,000 16,000 ■ Air Flow - Static Pressure Characteristics ・ PWM Duty Cycle ・ Operating Voltage Range → Air flow → Air flow PWM Duty Cycle 100％ (CFM) (m3/min) (CFM) (m3/min) (Pa) (inch H2O) (Pa) (inch H2O) 9HV0948P1G001 9HV0948P1G001 (Pa) DC 12 V PWM Duty Cycle 100％ DC 48 V (inch H2O) (Pa) (inch H2O) (CFM) (m3/min) (CFM) (m3/min) 800 4 1,000 600 200 400 2 1 3 0 1,200 5 6 0 20 40 60 80 100 120 140 160 180 200 2.0 2.5 1.5 0.5 1.0 0 4.0 4.5 3.5 3.0 800 4 1,000 600 200 400 2 1 3 0 1,200 5 6 0 20 40 60 80 100 120 140 160 180 200 2.0 2.5 1.5 0.5 1.0 0 4.0 4.5 3.5 3.0 800 4 1,000 600 200 400 2 1 3 0 1,200 5 6 0 20 40 60 80 100 120 140 160 180 200 2.0 2.5 1.5 0.5 1.0 0 4.0 4.5 3.5 3.0 800 4 1,000 600 200 400 2 1 3 0 1,200 5 6 0 20 40 60 80 100 120 140 160 180 200 2.0 2.5 1.5 0.5 1.0 0 4.0 4.5 3.5 3.0 PWM Duty Cycle 100% 0% 50% PWM Duty Cycle 100% 0% 50% 60 V 48 V 36 V → Air flow → Air flow 9HV0912P1G001 9HV0912P1G001 12.6 V 12 V 8 V |
