Low-Voltage PTC Thermostatic Heater

Обзор продукта
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. This temperature is dependent solely on the PTC thermistor’s Curie temperature and the applied voltage, and is largely independent of the ambient temperature.

PTC heaters are heating devices designed to utilize the constant-temperature heating characteristics of low-voltage PTC thermostatic heaters. In low- and medium-power heating applications, PTC heaters offer advantages unmatched by traditional heating elements, including constant temperature heating, Нет открытого пламени, high heat conversion efficiency, minimal influence from power supply voltage, and a long lifespan. Their use in electric heating appliances is increasingly favored by R&D Инженеры.

PTC thermistors for constant-temperature heating can be manufactured in a variety of shapes and specifications. Common shapes include discs, rectangles, strips, rings, and honeycomb structures. Combining these PTC heating elements with metal components can create various high-power PTC heaters. Примечание: High-power, low-voltage PTC thermostatic heaters have very high power requirements. Например, a 500W heater with a 12V supply draws a normal operating current of 500 ÷ 12 = 41.67A. Поэтому, 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, depending on customer requirements.

Notes on Use
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 + серебро, melt-blown aluminum, printed aluminum + серебро, and printed aluminum.
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) When multiple PTC heaters are used together, они должны быть связаны параллельно, не в серии.
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-cased model.

Notes on Use
1) The heating power decreases gradually after power is applied, eventually stabilizing. Stable power depends on operating conditions. The power of the same PTC heater can vary several times depending on the operating conditions. Чем быстрее рассеяние тепла, Чем больше стабильная сила; the higher the PTC surface temperature, Чем выше сила.
2) The surface temperature of the PTC heater is controlled by the PTC itself and can be controlled by disconnecting the circuit, 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) When using multiple PTCs, они должны быть связаны параллельно, не в серии.

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.
