Produktparameter und Spezifikationen

Leistungsbereich:
Household: 200W–2000W (electric heater, clothes dryer, air fryer)
Industrial: 2000W–15kW (industrial oven, car air conditioning heating system, medical device disinfection)

Betriebsspannung: 12V–480V AC/DC (global power grid compatible, error ≤±5%).

Widerstandswert: 10Ω–1000Ω (accurately matched by voltage and power, error ≤±3%).

Arbeitstemperatur:
Conventional model: continuous and stable operation 80°C–250°C (self-limiting temperature characteristics, automatic power reduction to prevent overheating).
High temperature model: short-term tolerance of 350°C (customized heat dissipation structure required).

Material:

PTC chip: barium titanate-based ceramic (Curie temperature 60°C–300°C adjustable, positive temperature coefficient characteristics).
​​    Heat dissipation structure: aluminum heat dissipation fins (thermal conductivity ≥ 200W/m·K, improve thermal efficiency).
​​    Surface treatment: anodized layer (corrosion resistant) or ceramic coating (high temperature resistant to 500°C).
Abmessungen:
Chip size: Φ10mm–Φ100mm (supports special-shaped customization).
Heat sink length: 50mm–1200mm, fin spacing 5mm–30mm.
​​    Service life: 20,000–80,000 hours (based on operating temperature and heat dissipation conditions).
​​    Customizable services: support power, voltage, Curie temperature adjustment, optional explosion-proof certification, IP protection level (such as IP68), integrated NTC sensor, etc.

Wesentliche Vorteile

​​Self-limiting temperature safety feature:
PTC ceramic Curie point effect, the resistance rises sharply when the temperature exceeds the set value, and the power is automatically reduced to a safe range, no external thermostat is required, and it prevents overheating and burning.
​​High efficiency and energy saving:
Thermal efficiency is ≥95%, electrical energy is directly converted into thermal energy, there is no open flame, and the energy consumption is 30% lower than that of traditional resistance wire heaters.
​​Fast response and silent operation:
The heating speed is ≤30 seconds (to 200°C), there is no mechanical vibration noise, and it is suitable for silent home appliances (such as air purifiers, medical equipment).
​​Long life and reliability:
There is no risk of oxide wire burning, the life is 2-3 times longer than that of resistance wire heaters, and it is resistant to frequent start and stop (>10,000 cycle tests).
​​Environmental adaptability:
Moisture-proof, dust-proof, and corrosion-resistant design (optional IP68/IP69K protection level), suitable for humid or harsh industrial environments.
​​Lightweight and compactness:
The aluminum heat sink has a low density (2.7g/cm³), and the volume is 50% smaller than that of traditional heaters, which is suitable for space-constrained scenarios.
​​Intelligent compatibility:
Supports PWM power regulation and IoT access (APP remote temperature control), and is suitable for smart home/Industry 4.0 systems.
​​Global Compliance​​:
CE, UL, CCC, RoHS certified
