Finder 7H.51.8.230.0400 Riscaldatore a convezione PTC 400W 110-230V AC/DC guida DIN

This PTC convection heater from Finder stands out with its self-regulating heating element, which automatically adjusts output as the ambient temperature changes, eliminating the need for external thermostats in many applications. Designed for electrical enclosure heating and anti-condensation, it operates on a wide voltage range of 110-230 V AC/DC, making it suitable for diverse industrial environments.

Highlights

• Self-regulating PTC heating element for safe, maintenance-free operation
• Wide input voltage range: 110-230 V AC/DC
• Compact DIN rail mounting for easy installation
• Anodized aluminum housing for efficient heat dissipation
• Passive convection design – no fan, silent operation

In daily use

The heater is mounted on a standard 35 mm DIN rail inside an electrical enclosure. Once connected, it warms the air inside the enclosure, preventing condensation and ensuring reliable operation of sensitive electronics. The PTC element self-limits its temperature, so the heater cannot overheat even if airflow is blocked. Its compact dimensions (93.1 x 88.2 x 98 mm) allow installation in tight spaces.
