ST1232-PTC Heater Principle and Functions
The company's technically produced PTC heaters come in several types such as cable type and terminal type, composed of PTC heating elements and corrugated aluminum strips bonded with high-temperature adhesive. This type of PTC heater has the advantages of low thermal resistance and high heat exchange efficiency, and is an automatic constant temperature, energy-saving electric heater. One of its prominent features lies in safety performance; under any application conditions, it will not produce the surface "red glow" phenomenon like tubular heaters, which can cause burns, fires, and other safety hazards.
ST1232-PTC Heater The most notable features are
1. Cost-saving, long lifespan.
Because the heater is not only made of special materials but also has integrated chips internally connected, it can control its own heating in real-time, avoiding damage caused by excessive temperature, thus giving it a much longer service life than other heaters.
2. Safe, green, and environmentally friendly.
The heater body is designed with multiple heating temperature levels below 200 degrees Celsius. Under any circumstances, the body does not glow red and has a protective insulating layer. No asbestos or other insulating materials are needed for cooling treatment in any application, and it can be used with confidence without the risk of burns or fire.
3. Energy saving.
Compared with electric heating tubes and resistance wire heating products, this product relies on the material's own characteristics to adjust its thermal power output according to changes in ambient temperature, so it can optimize and minimize the heater's electrical energy consumption. At the same time, the high heat efficiency material also greatly improves the utilization efficiency of electrical energy.
• Rapid heating, self-controlled temperature even when the fan fails, long service life
• Wide voltage range, can be designed between 12V-380V as needed
• Easy design, can be designed from low power to high power arbitrarily, and the appearance can also be designed according to requirements
• Non-combustible, safe and reliable, PTC does not glow red or produce open flames when heating
In medium and low power heating applications, PTC heaters have advantages that traditional heating elements cannot match, such as constant temperature heating, no open flames, high heat conversion rate, minimal influence from power supply voltage, and long natural lifespan. Their application in electric heating appliances is increasingly favored by R&D engineers.
Usage precautions :
(1) PTC heating elements have the characteristic of automatic constant temperature, and their own heating temperature also has a maximum value, which effectively prevents damage to themselves and other components in electrical equipment due to excessive heating.
(2) When PTC heating elements are used to heat liquids (such as water), if the liquid boils dry, the PTC heating elements will not be damaged.
(3) If PTC heating elements are used to heat cold air, when no air is blown, the PTC heating elements will not be damaged.
(5) Long service life: under normal environmental use, the lifespan can reach more than 10 years.
(6) Reliable operation: using the internal characteristics of PTC heating elements for temperature control, it will never overheat.
(7) Very wide operating voltage: when the operating voltage changes by 2 times, the surface temperature change is very small.
(9) When multiple PTC heating elements are used together, they should be connected in parallel, not in series.
(10) Different heat dissipation conditions cause significant differences in the heating power of PTC heating elements.
(11) The heating power decreases from high to low after power-on, and finally stabilizes. The stable power is related to the usage conditions; for the same PTC heater, different usage conditions may result in power differences of several times. The faster the heat dissipation, the higher the stable power; the higher the surface temperature of the PTC, the higher the power.
(12) The surface temperature of PTC heating elements is controlled by the PTC itself, or can be controlled by disconnecting the circuit, but cannot be controlled by adjusting the voltage.
(13) PTC itself has high reliability and long lifespan, but if improperly assembled, the product may experience unstable power and temperature.
