Specifications for ACDC Fan Sensors
Low-speed sensor outputs a signal when fan speed goes down to trip point or less. It is good to detect cooling degradation of fan.
Noise from inside the fan or from external devices may effect sensor output, please.
If you want detailed specification and reverse signal output,please contact SANYO DENKI.
Output circuit: Open collector
Sensor scheme
Example 1: when steady running
Example 2: when the rotor is locked when the fan motor is turned on and released after the start-up delay time.
