1. Characteristics
After switching on, the heating power is large, and then decrease, finally it become steady state. The steady state power change with appliance conditions. Faster is the heat conduction, higher is the steady state power; higher is the surface temperature, higher is the steady state power.
The surface temperature of PTC can be controlled by itself, control circuit may be omitted in most appliances.
Our PTC products are high reliable, long aging, but if they are assembled improperly, the end product may be loose, power or temperature may be instable.
1.4 It operates in long life, and has excellent insulation on high voltage. The surface temperature changes 5~10ºC only, when supplied voltage changes 2 time. In liquid heating appliance, when liquid was dried in the container, it's no problem.
Parallel connection is necessary for two or more PTC connection.
2. Application
Hair straightener, hair crimper, wax melting heater, vapor generator, humidifier, water boiler, liquid warmer, coffee warmer, polymer press-coating heater, hot glue gun, chocolate extruder, shoe dryer, hand/foot warmer, massager, physical therapy heater.
