PTC termistory pre ohrev na konštantnú teplotu

Prehľad produktov
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. Táto teplota závisí výlučne od Curieovej teploty termistora PTC a aplikovaného napätia, a je do značnej miery nezávislý od teploty okolia.

PTC ohrievače s konštantnou teplotou sú vykurovacie zariadenia navrhnuté tak, aby využívali vykurovacie charakteristiky PTC termistorov s konštantnou teplotou. V nízkej- a stredne výkonné vykurovacie aplikácie, PTC ohrievače ponúkajú výhody oproti tradičným vykurovacím telesám, ako je vykurovanie na konštantnú teplotu, žiadny otvorený oheň, vysoká účinnosť premeny tepla, minimálny vplyv napájacieho napätia, a dlhú životnosť. Ich použitie v elektrických vykurovacích spotrebičoch stále viac uprednostňuje R&D inžinieri.

PTC thermistors for constant temperature heating can be manufactured in a variety of shapes and specifications. Medzi bežné tvary patria disky, obdĺžniky, prúžky, krúžky, and honeycomb pores. Combining the above-mentioned PTC heating elements with metal components can create various high-power PTC heaters.

Usage Notes
1) Ohrievač PTC je vybavený automatickou reguláciou konštantnej teploty, eliminuje potrebu systému regulácie teploty. Je základnou súčasťou všetkých ohrievačov PTC.
2) K dispozícii sú štyri typy elektród: bezprúdový nikel + striebro, tavený fúkaný hliník, potlačený hliník + striebro, a potlačený hliník.
3) The operating voltage range is very wide. Even with a 2x increase in operating voltage, the surface temperature changes minimally.
4) Keď sa súčasne používa viacero ohrievačov PTC, they should be connected in parallel, not in series.
5) This product does not have lead wires or insulation. If this is not feasible, please select a model with an external insulation film or a metal housing.

Bezpečnostné opatrenia pri používaní
1) After power is applied, the heating power decreases gradually and then stabilizes. Stable power depends on operating conditions. The power of the same PTC heater can vary several times depending on operating conditions. The faster the heat dissipation, the greater the stable power; the higher the PTC surface temperature, the higher the power.
2) The surface temperature of the PTC heater is controlled by the PTC itself and can be controlled by disconnecting the circuit, 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 použití viacerých PTC, they should be connected in parallel, not in series.
