PTC heater SM 45W 110/240V SM 45 110-240

Compensating heater for electrical cabinets

PTC heater with a power of 45W, designed to maintain the appropriate temperature inside electrical cabinets. Its universal power supply (110-240V AC/DC) ensures wide compatibility with various installations. This simple solution prevents condensation and provides optimal working conditions for components.

Construction and application

The PTC (Positive Temperature Coefficient) heating element is characterized by self-regulation – its electrical resistance increases with temperature, which reduces the risk of overheating. Thanks to this, the heater maintains a stable temperature without the need for additional regulators. It is ideal for protecting sensitive components from the effects of low temperatures and humidity. Dimensions 150 x 28 x 50 mm allow for easy installation in a limited space.

Key features and benefits

• Wide power supply range (110-240V AC/DC): Enables use in different electrical networks without the need for transformers.
• PTC heating element: Provides self-regulation of temperature and protects against overheating, which increases the safety and lifespan of the device.
• Compact dimensions (107 x 67 mm): Facilitate installation even in tight electrical cabinets.
• Power 45W: Provides efficient heating with relatively low energy consumption.
• Application in electrical cabinets: Protects against condensation, corrosion and damage to components caused by low temperature.

The SM45 heater is a reliable solution for installers and end-users who care about the proper functioning of their electrical installations. Its simple construction and easy installation make it a practical choice for many applications.
