PTC Thermistors for Constant Temperature Heating

Produkto apžvalga
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. Ši temperatūra priklauso tik nuo PTC termistoriaus „Curie“ temperatūros ir taikomos įtampos, ir iš esmės nepriklauso nuo aplinkos temperatūros.

PTC constant temperature heaters are heating devices designed to utilize the constant temperature heating characteristics of PTC thermistors. In low- and medium-power heating applications, PTC heaters offer advantages over traditional heating elements, such as constant temperature heating, no open flames, high heat conversion efficiency, minimal influence from power supply voltage, ir ilga gyvenimo trukmė. Jų naudojimą elektriniuose šildymo prietaisuose vis labiau palankiai vertina r&D inžinieriai.

PTC thermistors for constant temperature heating can be manufactured in a variety of shapes and specifications. Įprastas formas sudaro diskai, stačiakampiai, juostelės, Žiedai, and honeycomb pores. Combining the above-mentioned PTC heating elements with metal components can create various high-power PTC heaters.

Usage Notes
1) The PTC heater features automatic constant temperature control, eliminating the need for a temperature control system. It is the core component of all PTC heaters.
2) Four electrode types are available: electroless nickel + silver, melt-blown aluminum, printed aluminum + silver, and printed aluminum.
3) The operating voltage range is very wide. Even with a 2x increase in operating voltage, the surface temperature changes minimally.
4) When multiple PTC heaters are used together, 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.

Temperatures can be designed between 60°C and 280°C, and operating voltages can be designed between 12V and 240V, depending on customer requirements.

Usage Precautions
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; Kuo aukštesnė PTC paviršiaus temperatūra, Kuo didesnė galia.
2) PTC šildytuvo paviršiaus temperatūra yra kontroliuojama pati PTC ir gali būti valdoma atjungus grandinę, 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) Kai naudojate kelis PTC, they should be connected in parallel, not in series.
