PTC (Positive Temperature Coefficient) heating elements can be heated by passing an electric current through them. When an electric current is applied, the resistance of the PTC material increases, causing it to heat up. This self-regulating property makes PTC heating elements efficient and safe for various applications such as heating pads, automotive heaters, and hair dryers. The amount of heat produced can be controlled by adjusting the voltage or current supplied to the PTC element. **

I would recommend the Corsair AXi Series AX1500i and the EVGA SuperNOVA 1600 T2 as 1500W power supplies. Both of these power supplies are highly efficient, with 80 Plus Titanium certification, and offer excellent performance and reliability. They also come with fully modular cables, allowing for easy cable management and customization. Additionally, they have received positive reviews from users and are known for their high build quality and stability. **

1. NTC thermistors: These are negative temperature coefficient thermistors that have a resistance that decreases as temperature increases. They can be used as an alternative to PTC KTY11 in temperature sensing applications. 2. RTD sensors: Resistance temperature detectors are another alternative to PTC KTY11. They are made of pure metals or metal alloys and their resistance changes with temperature. 3. Thermocouples: These are temperature sensors that consist of two different conductors that produce a voltage proportional to the temperature difference between the ends. They are commonly used in industrial and scientific applications. 4. Infrared sensors: These sensors detect temperature by measuring the infrared radiation emitted by an object. They can be used as an alternative to contact-based temperature sensors like PTC KTY11. 5. IC temperature sensors: Integrated circuit temperature sensors are small, low-cost sensors that can be used to measure temperature in electronic devices and systems. 6. Fiber optic sensors: These sensors use optical fibers to measure **

A PTC (positive temperature coefficient) re-settable fuse works by using a polymer material that has a high resistance at normal operating temperatures. When a high current or overcurrent condition occurs, the PTC fuse heats up and its resistance increases dramatically, effectively limiting the current flow and protecting the circuit. Once the overcurrent condition is removed, the PTC fuse cools down and its resistance decreases, allowing the circuit to function normally again. This self-resetting feature makes PTC fuses ideal for protecting electronic circuits from overcurrent events. **
