12V DC Cartridge Heater

12V DC Cartridge Heater

In order to obtain optimum performance from these products, it is advised that temperature sensing and control elements be used with them.Cartridge heaters have low/moderate watt density elements consisting of helical wire coils on ceramic former or high watt density elements with the heating element located close to the sheath, which is swaged to improve heat conduction.12V DC Cartridge Heater

It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation, long service life, no pollution, low price, etc. It also saves electric energy and is safe to use. It can be bent into various shapes, light and easy to assemble and disassemble.12V DC Cartridge Heater

Difference with other heaters:12V DC Cartridge Heater

1. Shape: The cartridge heater is one end (one end) outlet line, and the ordinary electric heating tube is two end outlet lines.
2. Internal structure: The winding method of the cartridge heater is different from that of the ordinary electric heating tube, especially the single-head electric head tube which is now imported, which is quite different from the ordinary electric heating tube.
3, The production process: the production process of the single-head electric heating tube has more processes than the ordinary electric heating tube, such as shrinking tube, which ensures that the single-head electric heating tube has higher power than the ordinary electric heating tube and has a long use time.

Performance requirements:12V DC Cartridge Heater

1 Heating time
Under the test voltage, the component should rise from ambient temperature to test temperature for no more than 15 minutes.

2 Rated power deviation
Under conditions of sufficient heat generation, the deviation of the rated power of the component shall not exceed the range specified below;
For components with rated power less than or equal to 100W: ±10%.
For components with rated power greater than 100W, it is +5% to -10% or 10W, whichever is greater.

3 Leakage current</DIV>
Cold leakage current and leakage current after water pressure and sealing test shall not exceed 0.5mA
The thermal leakage current at the operating temperature should not exceed the calculated value in the formula, but the maximum does not exceed 5 mA.
I=1/6 (tT×0.00001)
I—thermal leakage current mA
T—heat length mm
T-operating temperature °C
When multiple components are connected in series to the power supply, the leakage current test should be performed with this set of components as a whole.

4 Insulation resistance
Cold insulation resistance should be no less than 50MΩ at the factory inspection
After the sealing test, the insulation resistance after long-term storage or use should not exceed MΩ
The thermal insulation resistance at the working temperature shall not be lower than the calculated value in the formula, but the minimum shall be not less than 1 MΩ.
R = "(10-0.015T) / t" × 0.001
R—hot insulation resistance MΩ
T—heat length mm
T—operating temperature °C

5 Insulation compressive strength
The component shall be kept for 1 min under the specified test conditions and test voltage without flashover and breakdown.

6 Ability to withstand power failure
The component shall be capable of undergoing 2000 electrical and electronic tests under the specified test conditions without damage.

7 Overload capacity
The component shall withstand 30 cycles of overload test under specified test conditions and input power without damage.

8 Heat resistance
The component shall withstand 1000 cycles of heat resistance test under the specified test conditions and test voltage without damage.
