Fan Controller
KU LS2 PWM
The Universal PWM Fan Controller KU LS2 PWM is designed for professional and semi-professional applications. It controls the power / speed of the fans in accordance to the measured temperature. Multiple fans of the same type can be used in parallel. The digital temperature sensor works with a precision of +/- 1 °C and can be operated remotely. The fans are controlled by a pulse width modulation (PWM) with a switching frequency of typ. 18 kHz. Most off-the-shelf fans (incl. those with integrated electronic circuitry) in the supply voltage range of 12 ... 28 V DC can be used. Please notice the specifications of the fan manufacturer!
