Security: PTC products feature constant temperature heating with no open flame, high heat conversion efficiency, and minimal impact from supply voltage fluctuations, offering advantages over traditional heating elements. These characteristics make PTC heaters increasingly popular among R&D engineers for use in electric appliances. Energy Saving: PTC products have automatic energy-saving functionality. As the ambient temperature rises, the power output gradually decreases, reaching as low as 90%, 80%, or less of the rated power. Durability: When used under normal conditions without external damage, PTC products maintain performance even after thousands of on/off cycles. The primary factor in determining lifespan is the degree of power decay. Standard aging tests show less than 10% power reduction after 2000 hours of operation.
