- 02821.9-06 CSF 028 - Touch-Safe PTC Fan Heater
Product Description
- Low surface temperature
- Integrated thermostat
- Compact size
- Wide voltage range
- Double insulated protection
- DIN rail mountable
The CSF 028 fan heater prevents formation of condensation and provides evenly distributed interior air temperature in enclosures. The touch-safe plastic housing and the small size makes it ideal for use in enclosures with a high packing density. The heater is equipped with a fixed set point thermostat and is easily wired via external pressure clamps. Two different mounting options are available – DIN rail or screw tabs. The robust screw tab mounting is particularly suitable for applications with high vibration.
