PWM Driver Module, DC 12V 24V 48V 2 Channel 4-Wire Fan Temperature Controller Speed Governor Display Module for PC Fan/Alarm

Description: It is a PWM 4-Wire Fan Temperature Controller.It has a temperature and speed display and a stall alarm. Feature: 1>.Digital display. 2>.Wide operating voltage. 3>.Dual independent temperature control. 4>.Support button setting. 5>.Stall alarm function. Parameter: Product Name: PWM 4-Wire Fan Temperature Controller Work Voltage: DC 8V~60V Control Board Working Current: 35mA(12V),22mA (24V) Control Output Range: 10%~99.99% Temperature Probe Specification: NTC 10KB=3950 Temperature Measurement: -9.9?~99.9? Acceleration Temperature: 5?~94?, Full Speed Temperature: 10?~99? Speed Measurement: 10rpm~9990rpm Stall Alarm Speed: <375rpm Work Temperature: -25?~85? Work Humidity: 5%~95%RH Size: 64.5*64.5*15.5mm Speed Resolution: 1>.10rpm at >9990rpm(the display show "999"). 2>.Speed measurement is designed according to common 2-pole signal fans, most fans are 2-pole signals. Package: 1pcs PWM 4-Wire Fan Temperature Controller 1pcs NTC Temperature Sensor 1pcs Buzzer Note: 1>.The working voltage must be equal to the fan voltage.If you use a 12V fan but supply 24V,it will burn the fan. 2>.This product is not limited by the fan current,but the pin current of the fan interface on the board should not be greater than 3A.If you use a higher current fan,please connect the fan power cord directly to the main power. 3>.Please allow 1-2cm error due to manual measurement. Thanks for your understanding. 4>.Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard.
