Product Description body { font-family: Arial, sans-serif; line-height: 1.6; margin: 20px; } h2 { color: #333; } ul { list-style-type: none; padding: 0; } li { margin-bottom: 10px; } .note { color: #555; font-size: 0.9em; } Precise Details Features: 1. Crafted from high-quality materials ensuring reliability. 2. Compact size with an appealing aesthetic. 3. Temperature control speed controller for 2-3 wire fans. 4. Supports fan current range from 0.2-2A. 5. Suitable for a wide range of applications. Parameter: Design Power Supply Voltage: DC12V Voltage Range: DC9.5-14.5V (ensure compliance with fan voltage range) Circuit Self Consumption: Less than 70mA (tested at 12V) Fan Current: 0.2-2A (performance declines below 0.2A) Temperature Measurement Range: -9.9-99.9°C Temperature Measurement Error: Within 0-50°C, error < 1.2°C, otherwise error < 2°C Circuit Board Size: 70 x 19 x 11 mm (excluding protruding interfaces) Default Factory Settings: Acceleration temperature 30°C, full speed temperature 35°C, shutdown temperature 28°C, basic output 20 Key Description: Buttons "+" and "-": Switch display in operation and adjust values during parameter setting (long press for continuous adjustment). "OK" Button Functions: Short press in working mode to enter manual speed regulation setting, range 1-100. Short press again to save and exit. Long press in working mode to enter temperature parameter setting. Use "+" and "-" to modify parameters and "OK" to switch settings. Adjust settings for acceleration temperature "L**", full speed temperature "H**", and shutdown temperature "C**". Short press "OK" to save and exit without long pause. Temperature Parameter Details: "L_**": Acceleration temperature, range 5-94°C. Fan voltage increases as temperature exceeds this. "H**": Full speed temperature, range L**+5-99°C. Achieving or surpassing this results in full fan speed. "C**": Shutdown temperature, range 0-L**-2°C. If >0, low-temp shutdown is active; otherwise, the fan runs constantly at low temperatures. Note: The difference between "H**" and "L**" must be ≥5, and "C**" must be at least 2 below "L**". The system auto-adjusts to maintain these differences. Display Description: Three-digit Nixie Tube: Shows specific parameters and values. LED "x10 RPM": Displays speed; Nixie tube value multiplied by 10 is actual RPM. LED "°C": Displays temperature measured. LED "RUN": Indicates fan is running or off. Package Includes: 1x Module 1x Sensing Line (Blackhead/Ring Optional)
