Specifications of Carbon Fiber Heating Pad

Our carbon fiber heating pad is made with carbon fiber, not metal wire. It is waterproof and safe to dress, rub, fold or wash. The switch with  LED controller has four heating modes (Preheat, High, Mid and Low) for heat setting. The wire is specially designed and manufactured to fit the heating clothing requirements. The 12V DC power is lithium battery with high quality and high performance. All of them are integrated seamless to form the electric heating system for heated workwear. The following are the specifications of carbon fiber heating pad .

 

Inspection Process for Electric Heating  Sheet

All our Carbon Fiber Heating Pad for heated clothing should be inspected with strict processes to assure the quality before integrating into the heated clothes. The followed are the standard inspection processes.

1. Prepare the DC power supply and adjust the voltage to direct 12V.

2. Connect the heating sheet correctly with the power then turn on the switch.

3. Electric Current Testing. Open the electric heated sheet to see if the current meets the requirements of the above table. If it is out of range, the electric heating sheet should be rejected. The current value of the test will consistent with the tolerance of ±0.02A.

4. Washable Testing. Put the entire electric heating sheet into the water after immersed. Rub the sheet to simulate the effect of water washing at the same time. The sample is randomly selected for 5%.

5. Temperature protection Testing. Wrap up the electric heat sheet and monitor the temperature with the infrared thermostat. The current will be cut off (value 0) when the temperature reached 50ºC (+/- 5 ºC), and the current will be automatically connected when cooling, random sampling is 10%. The function will help avoiding fire if the user forgets to close the power.

6. All finished heated clothing products require 100% inspection.
