With the rise in thermal control demands, Sunon has released a selection of their most powerful and efficient PF series DC fans with standard 4-wire pulse-width modulation (PWM) input and tachometer output functions. The PWM function regulates the voltage-signal between duty-cycles to control the speed of the fan, while the Tachometer wire provides feedback on the fan's RPM.
Sunon's experienced R&D team has been producing customized PWM fan solutions for many years. They have taken the knowledge they have acquired and applied it to their standard products. Sunon's standard PWM fans are programmed with an exact and linear duty-cycle to offer precise thermal control. Sunon strives to help simplify the customer's design processing and lead time by making a reliable standard 4-wire PWM function readily available.
