Niskonaponski PTC termostatski grijač

Pregled proizvoda
Low-voltage PTC thermostatic heaters require only 3-24V voltage to maintain constant temperature heating. Their principle is that when power is applied, the PTC thermistor’s self-heating causes its resistance to enter the transition region, maintaining a constant surface temperature. This temperature is dependent solely on the PTC thermistor’s Curie temperature and the applied voltage, and is largely independent of the ambient temperature.

PTC grijači su uređaji za grijanje dizajnirani za korištenje karakteristika grijanja konstantne temperature niskonaponskih PTC termostatskih grijača. U niskom- i primjene grijanja srednje snage, PTC grijači nude prednosti neusporedive s tradicionalnim grijačima, uključujući grijanje na konstantnoj temperaturi, bez otvorenog plamena, visoka učinkovitost pretvorbe topline, minimalan utjecaj napona napajanja, i dug životni vijek. R. sve više daje prednost njihovoj upotrebi u električnim grijačima&D inženjeri.

PTC thermistors for constant-temperature heating can be manufactured in a variety of shapes and specifications. Common shapes include discs, rectangles, strips, rings, and honeycomb structures. Combining these PTC heating elements with metal components can create various high-power PTC heaters. Bilješka: High-power, low-voltage PTC thermostatic heaters have very high power requirements. Na primjer, a 500W heater with a 12V supply draws a normal operating current of 500 ÷ 12 = 41.67A. Stoga, the power supply must be capable of supplying at least 50A.

Low-voltage PTC heaters
Appearance and Structure

Temperatures can be designed between 50°C and 200°C, and operating voltages can be designed between 3V and 50V, depending on customer requirements.

Notes on Use
1) The PTC heater features automatic constant temperature control, eliminating the need for a temperature control system. It is the core component of all PTC heaters.
2) Four electrode types are available: electroless nickel + srebro, melt-blown aluminum, printed aluminum + srebro, and printed aluminum.
3) Unlike products designed for mains voltage, low-voltage products experience significant surface temperature fluctuations when the operating voltage fluctuates by more than 25%.
4) When multiple PTC heaters are used together, treba ih spojiti paralelno, ne u seriji.
5) This product does not have lead wires or insulation. If this is not feasible, please select a model with an external insulation film or a metal-cased model.

Low-Voltage Metal-Cased PTC Heater

Appearance and Structure

Notes on Use
1) The heating power decreases gradually after power is applied, eventually stabilizing. Stable power depends on operating conditions. The power of the same PTC heater can vary several times depending on the operating conditions. Što je brže odvođenje topline, veća je stabilna snaga; the higher the PTC surface temperature, veća je snaga.
2) The surface temperature of the PTC heater is controlled by the PTC itself and can be controlled by disconnecting the circuit, but it cannot be controlled by adjusting the voltage.
3) PTCs are inherently highly reliable and have a long lifespan, but improper assembly can cause power and temperature instability.
4) When using multiple PTCs, treba ih spojiti paralelno, ne u seriji.

We can design the temperature range from 50°C to 280°C and the operating voltage range from 3V to 50V according to customer requirements.
