ST1232-PTC Heater Principle and Function
The company uses technology to produce PTC heaters, which are divided into cable type and terminal type, etc. They are 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. It is an automatic constant temperature, energy-saving electric heater. One of its outstanding features lies in safety performance. Under any application, it will not produce the surface "reddening" phenomenon like electric heating tube heaters, thus causing safety hazards such as burns and fires.
ST1232-PTC Heater The most notable features are
1. Cost saving, long life.
Since the heater is not only made of special materials but also has an integrated chip internally, it can control its own heating in real time, avoiding damage caused by excessive temperature, thus having a much longer service life than other heaters.
2. Safe, green and environmentally friendly.
The designed heating temperature of the heater body is below 200 degrees Celsius in multiple levels. Under any circumstances, the body does not turn red and has a protective isolation layer. No insulation materials such as asbestos are needed for cooling treatment in any application. 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 characteristics of the material itself to adjust its thermal power output according to changes in ambient temperature. Therefore, it can optimize and minimize the power consumption of the heater. At the same time, the high heat generation efficiency material greatly improves the utilization efficiency of electric 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
• Convenient design, can be designed from low power to high power arbitrarily, and the appearance can also be designed as required
• Non-combustible, safe and reliable, PTC does not turn red or produce open flame when heating
In medium and low power heating applications, PTC heaters have advantages that traditional heating components cannot match, such as constant temperature heating, no open flame, high heat conversion rate, minimal influence from power supply voltage, and long natural life. Their application in electric heating appliances is increasingly favored by R&D engineers.
Usage Notes :
(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 due to excessive heating in electrical equipment.
(2) When PTC heating elements are used to heat liquids (such as water), they will not be damaged if the liquid dries up.
(3) If PTC heating elements are used to heat cold air, they will not be damaged when there is no air supply.
(5) Long service life, under normal environment, the life can reach more than 10 years.
(6) Reliable operation, using the internal characteristics of PTC heating elements to control temperature, never overheating.
(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 the PTC heating element is controlled by the PTC itself, or can be controlled by disconnecting the circuit, but cannot be controlled by adjusting the voltage.
(13) The PTC itself has high reliability and long life, but if improperly assembled, the product may experience unstable power and temperature.
