The characteristics and main parameters of the PTC electric heater safety tube The rated current refers to the larger working voltage that can be subjected to after the safety tube is broken. The operating voltage experienced on both sides of the fuse is much lower than its rated current during access. There are many types of fuses. The common fuse bonds can be divided into three categories: glass tube fuses with low discriminant talent, ceramic tube fuses with high discriminant gas and polymer material self-resettable fuses made of PPTC plastic polymer. Electric heaters do not need the temperature reaction of humidity sensors such as occupational thermostats and thermal resistance platinum thermal resistance to scald, 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 delineated rated current should exceed the reasonable operating voltage of the power supply circuit. Rated voltage rated voltage is the large amount of current that occurs in 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 is working and the shorter the application life. The important point here is that the gas temperature around the safety tube should not be confused with the 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 large amount of applied current is indirectly independent of power, voltage, difference, power factor (also known as power). RF coaxial connection has the advantages of no radiation safety and good vibration resistance. PTC heaters are energy efficient because their output power decreases significantly as the ambient temperature increases. When the air volume is kept fixed, the power of the PTC heater will be reduced to a certain extent, which plays a role in automatically adjusting the power to a certain extent. On the other hand, the lower the room temperature. Optimal without resistance and power dissipation. When the circuit is very, the current is too large or the circuit is short-circuited, the power supply can be quickly cut off, and the components such as the guard circuit can be guarded.
With the elevation of the surface temperature of the PTC electric heater, the power increases. Keep an eye out for 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 supply. Liquids (such as water) are heated with a positive temperature coefficient heating sheet, and the positive temperature coefficient heating sheet 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 without air supply. It has a long application life, which can exceed 10 years in normal environments. Work reliably, exercise the temperature control inside the PTC heater to achieve overtemperature. Unstable operating voltage width: A change in twice the operating voltage has little effect on the surface temperature. If multiple PTC electric heater fever plates are used at the same time, the parallel method should be accepted instead of the series. The difference in heat dissipation rate makes the heating power of PTC heaters have a large change. After turning on, 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 different several times. The heat of the electric heater is correspondingly fast, the temperature is accurately mastered, and the general heat obeys high.
