The characteristics and main parameters of the safety tube of PTC electric heater, the rated current refers to the larger working voltage that the safety tube can withstand after it is broken. The operating voltage on both sides of the fuse is much lower than its rated current during access. There are many types of fuses. The most common fuse bonds can be divided into three categories: glass tube fuses with low discriminant gas, ceramic tube fuses with high discriminant gas, and polymer material self-recovery fuses made of PPTC plastic polymers. Electric heaters do not need occupational thermostats and temperature reactions such as thermal resistance platinum thermal resistance and other humidity sensors can be burned, and its temperature regulation depends on its own raw material characteristics, so the product is much higher than the rest of the products. When applying safety tubes, the ordinary rated current should exceed the reasonable operating voltage of the power supply circuit. Rated voltage: Rated voltage is a large amount of current that occurs during the permanent operation of the safety tube. Assuming that the holding current is Ir, the rated voltage of the fuse tube should be the reduction rate of different standard fuse tubes. The higher the operating temperature, the hotter the fuse supervisor will work, and the shorter the application life. The point here is that the gas temperature around the safety tube should not be confused with room temperature. PTC ceramic heaters are diligent and thrifty, and have a long application life.
The higher the output power of the PTC heater, the faster the heating rate. PTC electric heater motor: electric heating (PTC electric heater, electric heating furnace, etc.). The sheer volume of the applied current indirectly is independent of power, voltage, difference, power factor (also known as power). RF coaxial connection has the advantages of radiation-free safety and good vibration resistance. The energy savings of PTC heaters are due to the fact that their output power decreases significantly as the ambient temperature rises. When the air volume remains fixed, the power of the PTC heater will be reduced to a certain extent, which plays a certain role in the benefit of automatic power adjustment. On the other hand, the lower the room temperature. Best without resistance and power dissipation. When the circuit is very large, the current is too large or the circuit is short-circuited, the power supply can be quickly cut off, and the circuit and other components can be guarded.
With the increase of the surface temperature of the PTC electric heater, the power increases. Please pay attention to the application of PTC electric heater electric furnace. PTC heaters have automatic thermostatic effect. No temperature control system is required. Can simply start the power. Liquids (such as water) are heated with a positive temperature coefficient heating sheet, and the positive temperature coefficient heating plate will not be damaged after drying. If a positive temperature coefficient heater is accepted to heat cold air, the positive temperature coefficient heater of the high temperature fan will not be damaged in the absence of air supply. It has a long application life, which can exceed 10 years in normal environments. The work is reliable, and the temperature control inside the PTC heater is exercised to achieve overtemperature. Unstable operating voltage width: A change in double operating voltage has little effect on the surface temperature. If multiple PTC electric heater fever plates are applied at the same time, the parallel method should be accepted instead of the series connection. The difference in heat dissipation rate makes the heating power of PTC heaters change greatly. After start-up, the heating power is stable from high to low. Power stability is related to application conditions, unified PTC electric heater fever, different application conditions, the power can be several times different. The electronic heater heat corresponds quickly, the temperature is accurately mastered, and the summary heat obeys high.
