FAQ – KLC PTC Heat Conductors

Q1: What is a PTC Heat Conductor?
A PTC (Positive Temperature Coefficient) Heat Conductor is a self-regulating heating element that uses PTC ceramic material. As the temperature rises, resistance increases, automatically limiting the current. This feature ensures safety, prevents overheating, and makes external temperature control unnecessary.

Q2: What are the advantages of KLC’s PTC Heat Conductors?

• Self-regulating thermal behavior (no thermostat needed)

• Safe and reliable — no risk of overheating

• Silent natural convection heating (no fan required)

• Wide voltage compatibility (AC/DC 12 V – 600 V)

• Energy-saving, fail-safe design

• Available in single or multi-stage heating versions

Q3: What are the typical applications?
KLC PTC Heat Conductors are widely used in:

• Moisture and frost prevention in electronics (e.g., PC motherboards)

• Household appliances such as steam irons and air purifiers

• Beauty and medical devices (skin care tools, sterilizers)

• Industrial control equipment requiring silent, reliable heating

Q4: How does the self-regulating function work?
When the conductor heats up, the resistance of the PTC ceramic element increases. This reduces current flow and stabilizes the temperature at a safe level. If ambient temperature drops or airflow increases, the conductor automatically delivers more heat output.

Q5: What are the available specifications?

• Max Power: UP to 2000 W

• Surface temperature: 60 °C – 240 °C

• Voltage range: AC/DC12V – 600 V

• Standard lead wire: 22 AWG, 210 mm

• Special option: 2- or 3-stage heating in one unit

Q6: Can PTC Heat Conductors be used continuously?
Yes. Thanks to their self-limiting property, KLC PTC Heat Conductors can operate continuously without overheating, as long as they are used within the specified voltage and ambient conditions.

Q7: Do PTC Heat Conductors require fans for operation?
No. KLC’s design uses aluminum fins for natural convection, which allows efficient heat transfer to the surrounding air without the need for a fan. However, additional airflow can enhance heat output if needed.

Q8: What safety standards do they comply with?
KLC PTC Heat Conductors are designed to meet international safety and environmental standards, including RoHS compliance. Custom designs can also be produced to meet UL, VDE, or CSA certification requirements.

Q9: Can KLC provide custom designs?
Yes. KLC offers tailored solutions, including custom dimensions, mounting methods, power ratings, and multi-stage heating configurations to fit different application needs.

Q10: How does airflow affect the heating performance?
With higher airflow, the surface temperature decreases, but the power consumption increases—resulting in more heat output. With lower airflow, the temperature increases, but power consumption decreases. This natural balance ensures stable, energy-efficient operation.
