3X 12V PWM 2-3 Wire Fan Temperature Controller Speed Governor Display Module for PC Fan/Alarm, Blackhead Probe

3X 12V PWM 2-3 Wire Fan Temperature Controller Speed Governor Display Module for PC Fan/Alarm, Blackhead Probe Περιγραφή

Features: 2-3 wire fan temperature control speed controller, digital display of temperature and speed, speed regulation based voltage (non-pulse output, no current sound), supports 0.2-2A current range fan, and can be shut down at low temperature.
Use high-quality materials with guaranteed quality, Small size and exquisite appearance. Wide application range.
Display Description: Three digit Nixie tube: display specific parameters and values.
LED "X10 RPM": the speed unit light, which is , and the Nixie tube displays the fan speed. The value multiplied by 10 is the actual measured speed. For example, if 256 is displayed, the actual fan speed is 2560RPM (r/min).
LED "": temperature unit light, which lights , and Nixie tube displays the temperature measured by the current probe. LED "RUN": Fan running indicator light, lit when the fan is running and turned off when the fan is turned off.

Parameter:
Design power supply voltage: DC12V
Voltage range: DC9.5-14.5V (circuit working voltage, please pay attention to the fan voltage range)
Circuit self consumption: less than 70mA (tested at 12V)
Fan current: 0.2-2A (control effect deteriorates below 0.2A)
Temperature measurement range: -9.9-99.9
Temperature measurement error: within the range of 0-50 , the error is less than 1.2 , and in other ranges, the error is less than 2 .
Default factory settings: acceleration (start) temperature 30 , full speed temperature 35 , shutdown temperature 28 , basic output 20.
Notice:
This speed controller output only supports 2-wire and 3-wire fan speed regulation, and does not support 4-wire PWM fans.
The Blackhead Probe is relatively suitable for air detection;
If you need to bring your own probe, please note that the probe resistance is 10K and the B value is 3950!
Probe Type: Blackhead
