Description: It is a step up down power supply module. It can be used as a power source. Feature: 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>.Under normal working conditions,the four values will be displayed in turn.You can quickly switch the value manually by pressing the + Button and - Button at any time.After manual switching,you will stay at this value for a long time before entering the wheel display state.You can shield the display of channel 2 as needed. Parameter: 1>.Work Voltage:DC 8V~60V. 2>.Control Board Working Current:35mA(12V),22mA (24V). 3>.Control Output Range:10%~100% . 4>.Temperature Probe Specification:NTC 10KB=3950. 5>.Temperature Measurement:-9.9℃~99.9℃. 6>Acceleration Temperature:5℃~94℃. Package: 1 x PWM 4-Wire Fan Temperature Controller 1x Buzzer 1x NTC Temperature Sensor
