Welcome to our store! We are pleased to present our fan temperature control, which is perfect for EBM four-wire fans and high-voltage EC fans. This control supports four-wire PWM fan temperature control with a 10V control signal, making it compatible with standard EBM four-wire fans. It also supports conventional high-voltage EC fans with a 10V PWM signal. One of the great features of this control is the ability to support power off at low temperature. You can easily turn off the fan power with PWM shutdown or an extended relay. With a wide voltage range of DC11-55V, this control can be used in various applications. It also supports 2.5KHz and 20KHz frequency settings and fans with reverse sequence. The temperature measurement range is -9.9-99.9℃, with a small error. The error in the range of 0-50℃ is less than 1.2℃, and the error in other ranges is less than 2℃. The package includes a fan temperature control regulator and a cable. 100% satisfaction: Our customers are our top priority.
