PTC heater SM 30W 110/240V SM 30 110-240

PTC heater SM 30W is a reliable solution for maintaining optimal temperature in electrical cabinets. Equipped with a 30W PTC heating element, it provides effective temperature compensation, protecting sensitive components from the negative effects of low temperatures. Universal power supply 110-240V AC/DC makes the heater compatible with various electrical installations.

Functionality and application

The SM 30W heater is primarily designed for use in control cabinets and electrical switchgear. Its function is to prevent condensation and maintain the temperature above the dew point, minimizing the risk of corrosion and damage to electronic components. The PTC heating element is self-regulating – its resistance increases with temperature, preventing overheating and ensuring safe operation of the device. This is particularly important in applications where temperature control is crucial for system reliability.

Construction and mounting

Compact dimensions (90 x 28 x 50 mm) allow for easy mounting of the heater in limited space. Mounting is done on a standard TS35 rail, which facilitates integration with existing infrastructure. The solid construction ensures durability and resistance to environmental conditions inside electrical cabinets. Additionally, the availability of accessories such as TRO 60, TRW 60, TWR 60 and TKW 60 allows you to adapt the heating system to individual needs.

The SM 30W heater is a product of the DEPRO (sometimes found as Rübsamen & Herr) brand, a renowned manufacturer of electrical components. Its width is 125 mm and its height is 67 mm. This makes it easy to adapt to different control cabinet configurations.
