PTC Convection Heater Nimbus D
The PTC Convection Heater Nimbus D is a compact natural convection heater for thermal control in cabinets. Nimbus D consist of a self-regulating PTC heating element pressed into a rugged aluminum profile. The convection heater is characterized by its high performance combined with its low weight and compact design. Nimbus D features a DIN clip that can be mounted on the wide or narrow side for easy and space-saving integration into the customer application. PTC convection heaters are particularly often used in control cabinets, where they protect electronic components from moisture and frost.
Nimbus D is available in eight different power versions from 30W to 100W. The heaters are suitable for a voltage range of 110 - 240V AC or DC (multi-voltage capable).
PTC Convection Heaters come with all advantages of the PTC heating technology. Thanks to the PTC effect, the heating elements dynamically adjust their power without exceeding a maximum temperature. High operational reliability and energy efficiency without any additional switching elements.
