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

Description: It is a PWM 4-Wire Fan temperature controller.It can be used for industrial fans. Feature: 1>.Digital display. 2>.Support EC four-wire fan control. 3>.Support low temperature shutdown fan. 4>.Wide voltage operation. 5>.Support anti-sequence fan. 6>.Support EBM four-wire fan. Parameter: Product Name:PWM 4-Wire Fan Temperature Controller Work Voltage:DC 11V~55V Work Current:0.1A(MAX) Fan Current:5A(MAX) PWM Range:5%~100% or 0% PWM Frequency:20KHz/2.5KHz PWM Signal Amplitude:10.5V(no load) Temperature Measurement Range:-9.9?~99.9? Work Temperature:-25?~85? Work Humidity:5%~95%RH Sensor Length:1 meter 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. Interface Introduction: 1>.Power interface:The main power input interface,which supplies power to the control board and fans. 2>.Fan interface:Fan output interface 3>.Temperature probe interface: connect NTC probe parameter 10K B=3950. 4>.Alarm signal port (WORK):High level output during normal operation,low level output when the fan is abnormal. 5>.Relay interface (RELAY):Expansion interface.Drives a 9V or 12V relay,which can be used to control the fan power line.When the fan control stops,the relay opens. Package: 1pcs PWM 4-Wire Fan Temperature Controller 1pcs NTC Temperature Sensor
