SANYO DENKI San Ace 92DC Fan ■ Features Low Noise Compared to our current product,111 noise level has been reduced by 5 dB(A). Energy Saving Power consumption has been reduced by approximately 13% compared to the current product.(2) High Static Pressure The maximum static pressure has increased by approximately 8% compared to the current product.(1) Rich Lineup The lineup offers four different rotational speeds for each of 12/24/48 V rated voltages. The broad lineup of fans enables you to choose the right fan best suited to your applications. (1) Comparison of the new product (model 9RA0948J1001) and current DC fan of the same size (model 9G0948J101). (2) Comparison of the new product (model 9RA0912G1001) and current DC fan of the same size (model 9G0912G101). The models listed below have ribs and pulse sensors with PWM control function. For models without ribs, append "1" to the end of model numbers. Models with the following sensor specifications are also available as options: Lock sensor

■ PWM Input Signal Example Input signal waveform VIH = 4.75 to 5.25 V　VIL = 0 to 0.4 V T1 1 PWM frequency 25 (kHz) = ×100 T T Current source (Isource) = 1.0 mA max. (when control voltage is 0 V) PWM duty cycle (%) = Current sink (Isink) = 1.0 mA max. (when control voltage is 5.25 V) VIL When the PWM control terminal is open, the fan speed is the same as the speed at 100% PWM duty cycle. The PWM signal can be used with open collector or drain input. Note that when using an open collector or drain input, T or inputting a different voltage or frequency, the speed relative to the PWM duty cycle...
