PTC heaters for communication cabinet

Application Area

The heaters are designed to heat the air in communication cabinet under either low termperature or high humidity,so as to faciliate ventilation or natural convection.Then electronic components inside could be well protected from condensation and work under appropriate temperature and humidity.

Features & Advantages

Patented for two technologies on inner structure, the automatic-constant-temperature and energy-conserved heater features in small thermal resistance and high heat-transfer efficiency. There are four types, two of  ventilation and two of natural convection, which have the following characteristics:  

1) Minimize power consumption by automatically adjusting output under different temperatures and improve energy efficiency through rapid-heating PTC elements;  

2) Unique patented structure to gurantee rapid heating-up and self-regurated temperature even under fan failure.Non combustible          

3) Long sevice life of more than 10 years;  

4)Applied in a wide range of voltage, with power varing little under either low voltage of 3-36V or high voltage of  110-600V         

5)Fast fixed into rail in cabinet due to the patented slot.
