PTC termistorji za ogrevanje s konstantno temperaturo

Pregled izdelka
The constant temperature heating characteristics of PTC thermistors for constant temperature heating are determined by the material properties. The principle is that when power is applied to the PTC thermistor, self-heating causes the component’s temperature to rise, causing the resistance value to enter the transition region and the current to drop rapidly. Consequently, the surface temperature of the PTC thermistor remains constant. Ta temperatura je odvisna izključno od Curiejeve temperature PTC termistorja in uporabljene napetosti, in je v veliki meri neodvisen od temperature okolja.

PTC grelniki s konstantno temperaturo so grelne naprave, zasnovane za izkoriščanje grelnih lastnosti s konstantno temperaturo PTC termistorjev. V nizkem- in srednje močne aplikacije za ogrevanje, PTC grelniki nudijo prednosti pred tradicionalnimi grelnimi elementi, kot je ogrevanje s konstantno temperaturo, brez odprtega ognja, visoka učinkovitost pretvorbe toplote, minimalen vpliv napajalne napetosti, in dolgo življenjsko dobo. R. vse bolj daje prednost njihovi uporabi v električnih grelnih napravah&D inženirji.

PTC thermistors for constant temperature heating can be manufactured in a variety of shapes and specifications. Običajne oblike vključujejo diske, pravokotniki, trakovi, prstani, and honeycomb pores. Combining the above-mentioned PTC heating elements with metal components can create various high-power PTC heaters.

Usage Notes
1) PTC grelec ima samodejno regulacijo konstantne temperature, odpravlja potrebo po sistemu za nadzor temperature. Je osrednja komponenta vseh grelnikov PTC.
2) Na voljo so štiri vrste elektrod: brezelektrični nikelj + srebro, talilno pihan aluminij, tiskan aluminij + srebro, in tiskan aluminij.
3) The operating voltage range is very wide. Even with a 2x increase in operating voltage, the surface temperature changes minimally.
4) Ko se skupaj uporablja več grelnikov PTC, morajo biti povezani vzporedno, ne v seriji.
5) Ta izdelek nima svinčenih žic ali izolacije. Če to ni izvedljivo, please select a model with an external insulation film or a metal housing.

Usage Precautions
1) After power is applied, the heating power decreases gradually and then stabilizes. Stabilna moč je odvisna od pogojev delovanja. The power of the same PTC heater can vary several times depending on operating conditions. Hitrejše je odvajanje toplote, večja je stabilna moč; višja je površinska temperatura PTC, večja je moč.
2) Površinsko temperaturo grelnika PTC nadzira sam PTC in jo je mogoče nadzorovati z odklopom tokokroga, but not by adjusting the voltage.
3) While PTCs are inherently highly reliable and have a long lifespan, improper assembly can result in unstable power and temperature.
4) Pri uporabi več PTC-jev, morajo biti povezani vzporedno, ne v seriji.
