DONGKER PWM Driver Module, DC 12V 24V 48V PWM 4-Wire Fan Temperature Controller Speed Governor Display Module for PC Fan/Alarm.

Parameter: 1. Product Name:PWM 4Wire Fan Temperature Controller 2. Work Voltage:DC 11V~55V 3. Work Current:0. 1A(MAX 4. Fan Current:5A(MAX 5. PWM Range:5%~100% or 0% 6. PWM Frequency:20KHz/2. 5KHz 7. PWM Signal Amplitude:10. 5V(no load 8. Temperature Measurement Range:9. 9℃~99. 9℃ 9. Work Temperature:25℃~85℃ 10. Work Humidity:5%~95%RH 11. Sensor Length:1 meter 12. Size:70. 5*40. 5*13. 5mm Note: 1. This is mainly designed for industrial fans. 2. Its interface is different from conventional chassis fans. Direct shutdown only supports fans with a signal shutdown function (fans stop after the speed control line is grounded. 3. If other fans need to be shut down,they can only be forced to cut off the fan power through an external relay. Package: 1. 1pcs PWM 4Wire Fan Temperature Controller 2. 1pcs NTC Temperature Sensor.
