12V CPU Fan Temperature Control PWM Speed Controller Module Alarm Buzzer Sensor

Description

12V PC CPU 4 Wire Fan Temperature Control PWM Speed Control Module with Alarm + Buzzer & SensorFeatures Support all within 12V 4A fans, synchronous rectifier output, high efficiency! Even if a large current work does not require additional heat sink! A plurality of fans can be used in parallel (total current does not exceed 5A), supports automatic temperature control and manumotive speed control, temperature control speed with four temperature zones for setting up, easy to apply in a variety of applications! It can be opened with a three-wire fan monitoring function (stall warning).1.channel: temperature control2.channel: manual operation3.High-Temp Alarm4.Automatic temperature control regulator speedSpecificationsWorking voltage:DC12V Circuit load capacity: maximum current per output 4A, the bus currents up 9AOutput Range: The first channel 20% -100, or 40% -100 (TFL = ON) The second channel and the third channel 10% -100(Note: Above range only for PWM range, the actual control effect will vary depending on the fan.)Temperature probe parameters: 50K B = 3950Thermostat temperature zone error: error depending on the temperature probe, generally 3-5%Stall alarm minimum speed: 700-800 rpmPackage included1x WS16 DC 12V 4A PWM PC CPU Fan Temperature Control Regulator Thermostat Speed Controller Switch 1x Temperature probe1x Buzzle
