Description

This PTC (Positive Temperature Coefficient) heater plate utilizes a ceramic element whose electrical resistance increases with temperature, providing inherent self-regulation and overheat protection. Upon reaching its designated 70°C setpoint, the resistance rises sharply, automatically limiting power draw and stabilizing the output temperature without requiring external control circuitry.

Designed for dry-burn operation, the heater features an insulated aluminum housing for efficient thermal conduction. Its 24V DC rating makes it compatible with common power supplies, battery packs, and automotive electrical systems, offering a safe, energy-efficient heating solution with rapid thermal response.

Key Features

  • Self-regulating PTC ceramic heating technology for automatic temperature control.
  • Compact footprint (35x21x5 mm) with an integrated 15cm connection cable.
  • Inherent safety with no open flame, red-hot elements, or harmful emissions.
  • Suitable for operation in humid environments due to its insulated construction.
  • Rapid thermal response, reaching operational temperature within seconds of power-on.
  • Designed for continuous, long-term dry-burn operation at a constant 70°C.
  • Low-voltage 24V DC operation ensures compatibility with electronic control systems.
  • Durable aluminum shell for effective heat conduction and mechanical protection.

Applications

  • Precise temperature maintenance in small appliances like coffee machines and egg cookers.
  • Localized heating modules for automotive seat warmers or defrosting systems.
  • Thermal control in beauty and wellness devices such as massagers and hyperthermia instruments.
  • Adhesive activation in low-temperature glue guns and craft tools.
  • Humidity-resistant heating for smart toilets and other bathroom electronics.

Frequently Asked Questions

What is the operating voltage and temperature of this PTC heater?

This heater is designed for 24V DC operation and is self-regulating, meaning it will automatically stabilize and maintain a constant surface temperature of approximately 70°C when powered. Exceeding the rated voltage can damage the element.

How does the self-regulating PTC feature work?

The Positive Temperature Coefficient (PTC) ceramic element increases its electrical resistance as its temperature rises. As it approaches the 70°C design point, the resistance increases significantly, reducing current flow and power consumption, which inherently limits further temperature rise without external controls.

Is this heater suitable for direct contact with surfaces or liquids?

This unit is designed for dry-burn operation with its aluminum housing acting as a heating surface. It is not submersible. It is suitable for conductive heating of adjacent components or air, but direct liquid contact or use as a cartridge heater in a bore is not recommended unless specifically designed for such an application.

What is the purpose of the 15cm cable?

The attached 15cm cable provides pre-wired leads for easy connection to a 24V DC power source, simplifying installation. Ensure connections are secure and properly insulated. The cable length is fixed; extensions should be made with adequate wire gauge to handle the operational current.
