PTC heater SM 20W 110-240V SM 20 110-240

Compensating heater for electrical cabinets

This is a reliable solution for maintaining optimal temperature inside electrical cabinets, especially in colder conditions. The PTC SM 20W heater is an element that protects against condensation and ensures proper operation of components. Its universal power supply (110-240V AC/DC) makes it compatible with various installations.

Construction and application

The heater uses a PTC (Positive Temperature Coefficient) heating element, which is characterized by self-regulation. This means that the heating power automatically adjusts to the ambient temperature, preventing overheating and ensuring stable operation. It is ideal for use in control cabinets, electrical switchboards and other enclosures where a minimum temperature needs to be maintained.

• Temperature compensation: Prevents condensation inside electrical cabinets.
• Self-regulation: The PTC element automatically adjusts the heating power to the surrounding conditions.
• Universal power supply: Can be powered by both alternating current (AC) and direct current (DC) in the range of 110-240V.
• Simple installation: Compact dimensions make installation easy in limited space.

Technical characteristics

The 20W heater has dimensions of 70 x 28 x 50 mm, and its width is 125 mm with a height of 67 mm. These compact dimensions allow for easy installation even in tight spaces inside the control cabinet. Made of durable materials, it ensures long-lasting and trouble-free operation. The product weight is approximately 0.19 kg – which facilitates transport and installation.
