As the preheating and softly-starting component of the electronic ballasts and energy-saving lamps, the intelligent ptc thermistor without power consumption can greatly increase the light switching time and operating time. Meanwhile, it can overcome the disadvantage of temperature-rising after preheating and starting of the electronic ballasts and energy-saving lamps, therefore improve the amount of the flowing light and the lighting efficiency of the lamps. It can be considered as another breakthrough revolution of green illumination electric appliances.
PTCR for time delay of lighting&ballast,which are applicable to various types of fluorescent lamp,electronic ballast,electronic energy-saving lamp and digital multi-meters. it can change hard start of the ballast and electronic energy saving lamp to pre-heated start and preheating time of the filament can come up to 0.4-2.0 seconds,which can greatly prolong service life of the fluorescent tube by over 4 times.
Advantages:
1. Used in the frequent-switching,typical switching life can pass over 100,000 times;
2. High reliability, good performance of safety and stability;
3. Wide operating temperature range;
-25 ~ +125℃(when V=0V)
0~ +60℃(when V=Vmax)
4. The withstanding voltage can reach to over 420-1000VAC;
5. The resistance will not drift in normal temperature.
6. Small dimension
7. Complete specifications
8. Stable delayed time
PTC thermistor Sensor Protection temperature range: 60～130℃- quick action time- good stability- small size and convenient installment- no setting again after over-heat protection- applied in: transformers, power parts, and all types of electricity machinery that work continuously, such as: switching power ...
With the characteristic of constant temperature, the PTC heater does not need the temperature-controlling system.-.If the PTC heater is used to heat the cold wind, it will not be destroyed when the wind is stopped. If the PTC heater is used to heat the liquid (eg: water), it will not be destroyed when the ...
Starting-circuit with PTC Thermistor has more advantages than the previous heavy-hammer starting-circuit.-. No trigger or noise, free Switching, and Long Operating Life-. It can control the current without other controller. The small size can be connected directly to compressors for use-. Support most of ...
MZ 31 series of PTC thermistor is a million- time safety device of automatic protection,recoverability, using repeatedly, and no trigger, noise or protective components that could protect and restore from abnormal temperature and current automatically,which called "auto restore fuse" and "ten-thousand-time ...
High reliability, good performance of safety and stability, and Used in the frequent-switching. The withstanding voltage can reach to over 600-1000VAC.Switching current can pass over 100,000 times: the resistance will not float.Applied in: energy-saving lamps, fluorescent electronic ballasts, and digital ...
NTC thermistor is a negative temperature coefficient thermistor. It is to use a single high-purity material, with close to theoretical density structure of high-performance ceramics. Thus, in the realization of miniaturization, it is also a resistance value, temperature characteristics of fluctuation is ...
