This amazing 12V temperature controller comes with a 10 - amp relay and a 3 - digit display. The display is super useful for setting and showing the temperature. The relay, which is normally open, closes when the temperature goes above the set value. It only re - opens when the temperature drops 2 degrees Celsius below the set temp. It's a great choice for automatically controlling an exhaust fan in the rear of a cargo van. Here are the key specs: Accuracy is ± 0.1 °C, control and backlash accuracies are 0.1 °C, refresh rate is 0.5S, temperature range is - 50 - 110 °C, high - temperature protection is from 0 - 110°C. It runs on DC12V, uses an NTC (10K0.5%) waterproof sensor for measuring. It can work in an environment of - 10 °C to 60 °C with 20% - 85% humidity. Its size is 48.5mm * 40.1mm * 15.8mm, hole size is 46 * 26.5mm. Power consumption is low with static current ≤35MA and pull current ≤65MA, and it weighs just 22.3G.
Using this temperature controller is easy. First, connect it to a 12V DC power source. Then, use the 3 - digit display to set your desired temperature. The controller will start monitoring the temperature right away. When the temperature goes above the set value, the relay will close, and when it drops 2 degrees Celsius below the set temp, the relay will open. If you're using it to control an exhaust fan in a cargo van, just connect the fan to the relay. As for maintenance, keep it in an environment within - 10 °C to 60 °C with 20% - 85% humidity. Don't expose it to extreme temperatures or high humidity for long periods. Check the connections regularly to make sure they're secure. If there are any issues, refer to the technical specifications or contact customer support.
