Product Data Sheet RER175-42/14/2TDMLPU Information to the curve: 0 % - 7% PWM: 0 1/min 7 % PWM: 800 1/min (Fan on, comming from 0% PWM) 7 % - 10% PWM: 800 1/min (corresponding to min. speed) 10 % - 90% PWM: linear increasing curve 90 % - 100% PWM: 3.400 1/min (corresponding to max. speed) 7 % - 5 % PWM: linear decreasing curve (comming from 100% PWM) 5 % PWM: 600 1/min or 0 1/min (Fan off, comming from 100% PWM) 3.
Product Data Sheet RER175-42/14/2TDMLPU 3.3 Electrical Interface - Output Tacho type /2 (open collector) Please note: At zero speed the tacho signal is at a static HIGH. It will be also HIGH when the fan is still spinning, but the speed control signal is set to zero speed already. The tacho signal is only activated after the start-up is completed.
