The intelligent heating film control board is designed for multi-scenario temperature control needs, supporting full compatibility with carbon fiber/PTC/metal films. It integrates a PID algorithm and ±0.5°C high-precision temperature control, with triple protections against overvoltage/overcurrent/short circuits, IP68 waterproof and anti-vibration capabilities, and adapts to wide voltage inputs of 12-24V and high-power loads of 2000W. Built-in Bluetooth/WiFi IoT interfaces enable remote programming of multi-segment temperature control curves, meeting strict requirements for new energy vehicle battery preheating, industrial equipment constant temperature, and smart home heating. It is certified by CE/FCC and automotive-grade ISO 16750.
