Function:PTC Thermistor Special for over current,overload protection of welding machines. MZ31 series 15P,16P,19P PTC thermistor are million- time safety thermistor of automatic circuit protection,recoverability, using repeatedly, and no trigger, noise or protective component that could protect and restore from abnormal temperature and current automatically,which called "auto restore fuse" and "ten-thousand-time fuse".Recoverability, using repeatedly, and no trigger, noise or sparks.
Read MoreSend InquiryMZ4 series PTC thermistors are used in various types of fluorescent lamps, electronic ballasts and electronic energy-saving lamps as preheating-starting components. Preheating of the electrodes lengthens the life of the lamps and the number of switching cycles significantly. Ampfort has been working at PTCR'S research, development and manufacturing for ten years.
Read MoreSend InquiryMZ5 series PTC thermistors are used in all kinds of fluorescent lamp electronic ballasts and electronic energy-saving lamps. There is no need to change the circuit and the product is directly connected to the two ends of the resonant capacitor of the lamp tube, which can change the electronic ballast and electronic energy-saving lamp. The hard start is the preheating start, and the preheating time of the filament is 0.4~2 seconds, which can extend the life of the lamp more than 4 times.
