12V PTC Ceramic Fan Heater Module 50W – Constant Temperature Electric Heating Element with Cooling Fan and Mounting Brackets (60×60×42mm)

Compact 12V heating for DIY enclosures and small warm-air applications: this 12V PTC ceramic fan heater module delivers convenient heat in a small footprint, combining a self-regulating PTC heating element with an integrated fan to push warm air across your target area. It is designed for makers and technicians who need controlled heating in small spaces such as project boxes, electronics cabinets, sensor housings, and prototype devices.

PTC ceramic self-regulating behavior: unlike some heating wires that can continue rising in temperature aggressively, a PTC element increases its resistance as it gets hotter. This characteristic helps the heater naturally limit overheating and maintain a more stable operating range in typical airflow conditions. In practice, this makes the module more forgiving for enclosure heating and anti-condensation tasks (final temperature depends on airflow, ambient temperature, insulation, and installation).

Integrated fan for better heat distribution: the built-in fan moves air over the PTC element and helps distribute warmth more evenly inside a box or across a small area. Airflow can improve heating efficiency and reduce hot spots, especially when the heater is mounted inside a cabinet, equipment box, or 3D-printed enclosure.

Typical use cases:

• Electronics enclosures needing mild internal heating
• Anti-condensation and dehumidifying projects (with proper ventilation)
• Small cabinets, test boxes, and instrument housings
• 3D printer or filament storage enclosures (prototype setups)
• DIY warm-air projects and educational demonstrations

Easy mounting: the module includes mounting brackets and a compact body size (approx. 60×60×42mm), making it easier to install on panels, frames, or inside project cases. Use appropriate screws and keep sufficient clearance around the air inlet and outlet to avoid restricting airflow.

Power notes: this is a DC 12V module rated around 50W under typical conditions, meaning it can draw several amps during operation. Use a suitable 12V power supply with adequate current headroom, and wire with appropriate gauge. Because power draw and temperature can vary with airflow and environment, always test your setup under real conditions before continuous use.

Safety guidance: this heater becomes hot during operation. Keep away from flammable materials, avoid touching the heating surface, and do not operate unattended in high-risk environments. Install in a ventilated enclosure and ensure the fan can run freely. For critical applications, add external temperature protection and proper fusing.

What you get: 1× 12V 50W PTC ceramic fan heater module with mounting brackets—an effective choice for small enclosure heating and DIY temperature-control projects.
