PTC Heat Conductor Features


PTC Heat Conductor

Taiwan KLC’s PTC Heat Conductors comes in various sizes and mounting options for ease of installation. Utilizing PTC’s self-regulating characteristics, PTC Heat Conductors is a safe and energy-saving choice for your product design. Some of its typical applications includes, PC mother board heating, steam ironing, moisture control, frost protection and any medium to low heating products.  PTC heat conductors of LCH-H~K series are effective natural convection heaters, with aluminum extrusion fins allowing effective heat transfer into ambient air without the use of fan. Nevertheless, types LCH-I and K can also be used as air heaters (please select LCH-H ~LCH-K tab below for more information).

  • High heating efficiency
  • Low electricity consumption
  • Low cost
  • Very low to no noise level (compared with fan heater)
  • Available in wide voltage range (12V~600V)
  • High reliability with self-regulating characteristic
  • Heating power(W) and self-regulating function is in correlation to the ambient environment (temperature, air flow, air volume)
  • Most suitable for heating, heat retaining and constant temperature maintaining, with almost unlimited applications!

Our NEW Multi-Stage Heating PTC Heat Conductor provides higher flexibility in temperature control, by allowing two or three temperature settings in a single heating unit. Multistage heating unit can be designed into all LCH types (LCH-A to LCH-I) PTC heat conductors. For more information on this compact multi-stage heater, please select the “Multi-Stage Heating” tab below.

Suitable for medical assistance, beauty treatment, stream ironing, moisture control, electronic heating, health treatment, air purifier etc. for all medium to low heating products.

 

PTC Heat Conductor General Specifications


  • Power : 2W ~ 2000W
  • Surface Temperature : 60°C ~ 240°C
  • Voltage :AC/DC 5V~500V
  • Standard Lead Wire :22AWG 210mm (black)

 

PTC Heat Conductor Application Notes


  • The power(wattage) of PTC heat conductor increases with the heat dissipation rate. When heat is retained under condition with no airflow (low heat dissipation), the surface temperature of the PTC conductor will reach curie temperature (Ct), the power(W) will then decrease dramatically. On the other hand, when the heat dissipation rate is high (under the condition of low ambient temperature, underwater or large airflow), this will cause the surface temperature of PTC heat conductor to decrease, the power of PTC heat conductor will then increase to regulate the temperature.
  • The wattage(power) in the MAX POWER is the power(W) under the most effective heat transmission condition based on surface temperature of 240°C. The General heat transmission power is 5%~80% of the maximum power specified. For indirect heating of water, the power may be just 15%~60% of the maximum power.  The power(W) varies in relation to the contact material, heat sink, heat dissipation area, ambient temperature, airflow and product application.
  • Customized models can be designed according to customers’ requirement (tooling cost may apply).
  • Calculation of Relative Power for other Surface Temperatures:
    The Maximum Power listed in the Specifications tables is for PTC Heat Conductors with surface temperature of 240°C (220°C for some LCH types). If the required surface temperature is 120°C, the relative power of the Max. Power(W) can be calculated using the formula below:
    Temperature Rise(@240°C) = 240°C – ambient temperature = 240°C – 20°C = 220°C
    Temperature Rise(@120°C) = 120°C – ambient temperature = 120°C – 20°C = 100°C
    Relative Power(@120°C)  = Max. Power from table x Temp. Rise(120°C)/Temp. Rise(240°C)
    = 120W x 100°C/220°C = 54.5W
    Relative Power is approximately 54.5W for 120°C

LCH-H~K Type Specification

The PTC heat conductors from LCH-H model to K model all feature a heat dissipation fin design that promotes natural heat convection. They can effectively raise the ambient temperature without the need for an additional fan. With PTC characteristics and heat dissipation fins, the PTC heat conductors of the LCH-H to K series not only ensure safety but also operate quietly (without the noise generated by fans). If there is a need for rapid heating in the environment, both the LCH-I and LCH-K models can be equipped with an additional fan on the heat conduction side to facilitate quick heat dissipation and rapidly raise the ambient temperature.
