Description

Constant Temperature PTC Heating Element Thermostat Heater Plate 5V/12V/24V/220V
Product Information:
👉
Reminder:
It is strictly forbidden to remove the yellow film on the surface, and it is strictly forbidden to soak in water, bend, or open holes. It can be dried.
👉 For example, 12V/60 ℃ refers to the voltage of 12 volts, and the surface of the heating element is dry-fired at a constant temperature of about 60 degrees. When the temperature rises, it is 2.5 watts. After the heating plate is kept at a constant temperature, the resistance becomes larger, the current becomes smaller, and the power is reduced to about 1 watt.
❗ Note:
The temperature marked here is the maximum temperature limit value of the surface temperature of the heating element in the state of empty burning, this temperature does not represent the temperature during use; the use temperature is controlled by the environment and on-site heat absorption; the surface temperature limit temperature of the empty burning surface and the use temperature They are two completely different temperatures; please explain this misunderstanding.
1. Product name
PTC is the English abbreviation of positive temperature coefficient thermistor
2. Working principle
The internal heating element of the PTC heater is a positive temperature coefficient thermistor, and its resistance value shows a step increase with the increase of the temperature of the PTC thermistor body. The higher the temperature, the greater the resistance value.
3. Product advantages
Dry burning, energy saving, long life, no open flame, suitable for low-power antipyretic preheating and dehumidification of micro equipment.
4. Power selection
It can be directly connected to the rated voltage, both AC and DC, without positive and negative poles.
Take a 12V heating plate as an example, it can be connected to AC and DC 12V, and the power supply current must be greater than the maximum heating current of the heating plate, otherwise the heating plate cannot be brought.
5. About power
After the PTC heating plate is energized, the power varies from small to large and then to small, and finally stabilizes. The stable power is directly related to the heat dissipation. The heat dissipation is fast and the power consumption is also high. We target the maximum dissipation power, and the actual power used is less than the maximum dissipation power.
It is strictly forbidden to use it in corrosive, flammable and explosive occasions, it is strictly forbidden to put it into water, it is strictly forbidden to knock it, and it is strictly forbidden to open holes.
Multiple heating pads with the same voltage can be connected in parallel, and multiple heating pads can be installed side by side.
Multiple heating pieces should be used in parallel, the more heating pieces, the higher the power.
Reducing the power supply voltage will make the heating time longer and the power smaller, but the temperature will remain basically constant (a slight drop in temperature).
6. Purpose
Battery, security, medical, scientific research, industrial motor, aerospace, and other electronic and electrical low-power heating, preheating, dehumidification and heat preservation.
It is widely used, such as electric mosquito coil heater, shoe warmer heater, incense burner heater, fan heater heater, electric cup heater, water dispenser heater, coffee maker heater, yogurt maker heater, auto parts insulation, Diesel alcohol heating, instrument heating and dehumidification, solenoid valve antifreeze, power distribution cabinet dehumidification and dehumidification, constant temperature preheating of electronic components, portable heating elements, and many other uses that can be developed.
Detailed product description
1. The power of PTC products is related to heat dissipation conditions! The better the heat dissipation, the greater the power.
2. The maximum power is to dissipate heat on both sides of the heating plate at the same time under extremely good conditions. If the heating plate only feel the object on one side, the maximum power is directly reduced to half.
3. Dry burning power is the power of natural heat dissipation when the heating plate is hung in the air without feeling anything.
4. The rated temperature we marked is the dry burning surface temperature of the heating plate, which is the surface temperature of our heating plate hanging in the air when it does not feel any objects. Different media, contact quality, size, thickness, material, ambient temperature, air circulation, etc. of the heated object all determine the stable temperature of the heated object. So this is not only determined by our heating products, it is generally recommended that users test to know.
5. Electric heating products have impulse power (impulse current), which is generally 1~2 times of the maximum power.
6. Low-voltage products must not only meet their voltage, but also need to pay attention to the current. If the power supply current cannot meet the inrush current of the product, the product will heat up slowly, the temperature will be low, and even a short circuit may occur! ! !
PTC features and advantages:
1. Safety: PTC products have the incomparable advantages of traditional heating elements, such as constant temperature heating, no open flame, high thermal conversion rate, and little influence by power supply voltage. The application in electric heating appliances is more and more favored by R&D engineers.
2. Energy saving: PTC products have the characteristics of automatic energy saving. When the heater raises the ambient temperature, its power will gradually decrease, only 90%, 80%, or less of the rated power.
3. Long lifespan: PTC products are not damaged due to their own reasons during normal use, and even tens of thousands of repeated switches have no effect on their performance. The standard for measuring their lifespan is their aging degree. The general standard is that the power attenuation after 2000 hours of operation is less than 10%.
