Low-Voltage PTC Thermostatic Heater

产品概述
Low-voltage PTC thermostatic heaters require only 3-24V voltage to maintain constant temperature heating. Their principle is that when power is applied, the PTC thermistor’s self-heating causes its resistance to enter the transition region, maintaining a constant surface temperature. 该温度仅取决于PTC Thermistor的Curie温度和施加的电压, 并且主要与环境温度无关.

PTC heaters are heating devices designed to utilize the constant-temperature heating characteristics of low-voltage PTC thermostatic heaters. 低- 和中型加热应用, PTC heaters offer advantages unmatched by traditional heating elements, including constant temperature heating, 没有开放的火焰, 高热转化效率, 电源电压最小的影响, 和寿命很长. 它们在电气加热设备中的使用越来越受到R的青睐&D工程师.

PTC thermistors for constant-temperature heating can be manufactured in a variety of shapes and specifications. 常见形状包括光盘, 矩形, 条, 戒指, and honeycomb structures. Combining these PTC heating elements with metal components can create various high-power PTC heaters. 笔记: High-power, low-voltage PTC thermostatic heaters have very high power requirements. 例如, a 500W heater with a 12V supply draws a normal operating current of 500 ÷ 12 = 41.67A. 所以, the power supply must be capable of supplying at least 50A.

Low-voltage PTC heaters
Appearance and Structure

Temperatures can be designed between 50°C and 200°C, and operating voltages can be designed between 3V and 50V, 取决于客户要求.

Notes on Use
1) PTC加热器具有自动恒温控制, 消除对温度控制系统的需求. 它是所有PTC加热器的核心组成部分.
2) 有四种电极类型可用: 电镍 + 银, 融化的铝, 印刷铝 + 银, 和印刷铝.
3) Unlike products designed for mains voltage, low-voltage products experience significant surface temperature fluctuations when the operating voltage fluctuates by more than 25%.
4) 当多个PTC加热器一起使用时, 他们应该并行连接, 不串联.
5) 该产品没有导线或绝缘材料. 如果这不可行, please select a model with an external insulation film or a metal-cased model.

Notes on Use
1) The heating power decreases gradually after power is applied, eventually stabilizing. 稳定的功率取决于操作条件. The power of the same PTC heater can vary several times depending on the operating conditions. 散热速度越快, 稳定力量越大; PTC表面温度越高, 力量越高.
2) PTC加热器的表面温度由PTC本身控制，可以通过断开电路来控制, but it cannot be controlled by adjusting the voltage.
3) PTCs are inherently highly reliable and have a long lifespan, but improper assembly can cause power and temperature instability.
4) 使用多个PTC时, 他们应该并行连接, 不串联.

We can design the temperature range from 50°C to 280°C and the operating voltage range from 3V to 50V according to customer requirements.
