Features: Wide voltages input supports DC12V-24V input, which is suitable for various power supply environment (such as battery and industrial power supply). In actual test, some users can still work stably with 24V feedback. The NTC3950 thermistor is used for temperature control. The temperature control ranges of the factory is -50~110℃, and the temperature drift is about 0.2℃ (it may change due to circuit adjustment after actual modification). Digital real-time monitoring is equipped with LED display screen, which displays current temperature and set temperature in real time, and supports operation. MOS transistors output control is different from the traditional. MOS transistors is adopted to realize contactless on-off with fast response speed (microsecond level) and long service life (about 100,000 times or more), which is suitable for high-frequency control scene. Supports upper and lower temperature control and constant temperature keep modes, and the threshold can be adjusted by potentiometer or knob. Some models support pulse width modulation.
