Item Type: PTC Heating Plate Element Size: Approx. 200 x 21 x 5mm / 7.9 x 0.8 x 0.2in Shell Material: Aluminum Heating Material: PTC ceramic heating sheet Line Length: Approx. 28mm / 1.1in Temperature Error: 10 Rated Voltage: AC220V Application: Coffee machine, smart toilet, massager, hyperthermia, glue gun, mosquito killer, censer, beauty salon, egg cooker Temperature Description: 1. Marked Temperature: The surface temperature of the product without touching any objects in an environment of 24 2. Use Temperature: The increase in temperature is not only determined by the heating plate. Large space, good insulation, and basic temperature are all important factors. Therefore, the stable temperature of the heated object under different use environments cannot be estimated. 3. Temperature Control: Uncontrollable, choose according to your needs, if you need to control the temperature flexibly, you can match the temperature control equipment by yourself Power Description: Maximum Power: The power marked in the option means that both sides of the heating plate can dissipate heat under extremely good conditions at the same time. If the heating plate only touches the object on one side, the maximum power is directly reduced to half Actual Power: The power of the PTC heating plate is not a fixed value, it is a range. The better the actual power is, the greater the power (similar to the principle of inverter air conditioning) Impact Power: About 2 times the maximum power Dry Burning Power: About 20% of the maximum power (power for natural heat dissipation when not touching any objects) Low-voltage Products: Not only need to meet its voltage, but also need to pay attention to the current. If the power supply current cannot meet the product's impulse current, low-voltage products will have the possibility of slow product temperature rise, low temperature, or even short circuit. PTC Features: Dissipated Power: Due to the different usage methods of users and the energy-saving characteristics of PTC itself, the power in actual use is mostly within the range of 50%-200% of its rated power (the better the heat dissipation, the greater the power) Dry Burning Power: About 20% of rated power (this product is dry burning type)
