Description
The CHR50 is a semiconductor PTC (Positive Temperature Coefficient) enclosure heater designed for efficient and self-regulating heating inside electrical control panels and industrial enclosures. It provides reliable anti-condensation and frost protection by maintaining a stable internal temperature, ensuring safe operation of sensitive electrical and electronic components.
It is widely used in automation panels, switchgear cabinets, telecom enclosures, outdoor electrical boxes, and industrial control systems where moisture control and temperature stability are essential.
The PTC heating element automatically adjusts its resistance based on temperature, making the heater energy-efficient, safe, and maintenance-free with no risk of overheating.
