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 supply, automatic lathe, electro-thermal oven and so on.
MZ5 series as a temperature sensing is in small size and low heat capacity,can display overheating situation of power components in switching mode power supply effectively. Making use of the characteristics that the resistance of PTC thermistor sensor increases sharply above curie temperature, when ambient temperature increases abnormally, protective circuit with installed PTC thermistor sensor will turn on or cut off loop through resistance changing to achieve protection purpose.
Advantages:
1.Small size and convenient installment;
2.Good stability
3.Wide protection temperature range：60-130 degree Celsius
4.Quick action
5.No resetting after over-heat protection
6.Wide application
Application:
1.Switching power supply
2.all types
of electricity machinery that work continuously such as automatic
lathe, motors, electro-thermal oven, ball grinder etc.
3.Transformers
4.Power parts
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 ...
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 ...
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 ...
