PTC Thermistors for Constant Temperature Heating

產品概述
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. 該溫度僅取決於PTC Thermistor的Curie溫度和施加的電壓, 並且主要與環境溫度無關.

PTC constant temperature heaters are heating devices designed to utilize the constant temperature heating characteristics of PTC thermistors. 低- 和中型加熱應用, PTC heaters offer advantages over traditional heating elements, such as constant temperature heating, no open flames, 高熱轉化效率, 電源電壓最小的影響, 和壽命很長. 它們在電氣加熱設備中的使用越來越受到R的青睞&D工程師.

PTC thermistors for constant temperature heating can be manufactured in a variety of shapes and specifications. 常見形狀包括光盤, 矩形, 條, 戒指, and honeycomb pores. Combining the above-mentioned PTC heating elements with metal components can create various high-power PTC heaters.

Usage Notes
1) PTC加熱器具有自動恆溫控制, 消除對溫度控制系統的需求. 它是所有PTC加熱器的核心組成部分.
2) 有四種電極類型可用: 電鎳 + 銀, 融化的鋁, 印刷鋁 + 銀, 和印刷鋁.
3) The operating voltage range is very wide. Even with a 2x increase in operating voltage, the surface temperature changes minimally.
4) 當多個PTC加熱器一起使用時, 他們應該並行連接, 不串聯.
5) 該產品沒有導線或絕緣材料. 如果這不可行, 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. 穩定的功率取決於操作條件. The power of the same PTC heater can vary several times depending on operating conditions. 散熱速度越快, 穩定力量越大; PTC表面溫度越高, 力量越高.
2) PTC加熱器的表面溫度由PTC本身控制，可以通過斷開電路來控制, 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) 使用多個PTC時, 他們應該並行連接, 不串聯.
