The CS 028 PTC fan heater prevents formation of condensation and provides an evenly distributed interior air temperature in enclosures. The electrical enclosure heater is connected using the internal terminal connectors. The surface temperatures on the accessible side surfaces of the housing are minimized as a result of the heater design.
The CS 028″s small size make it ideal for use in enclosures where space is at a premium. These PTC heaters warm the air inside enclosures, preventing water vapor from condensing on components while providing the greatest possible air circulation and low energy consumption.
Features:
- Compact Size
- Quiet Operation
- Heating power adjusts to ambient temperature
- DIN rail or screw mount available
