03103.9-00

Overview

The Stego HV 031 (Model 03103.9-00) is a high-performance axial fan heater designed for electrical cabinet thermal management. It features a cast aluminum body with a glass bead finish and an integrated axial fan with ball bearings. The unit utilizes a high-performance cartridge heating element protected by a built-in temperature limiter. It supports DIN rail mounting (EN 60715) in a horizontal position, operates within -45°C to +70°C, and carries UL, EAC, and VDE certifications.

Feature Summary

• Integrated axial fan with ball bearings for efficient air circulation
• Built-in temperature limiter for overheating protection
• Cast aluminum housing with durable glass bead finish
• Standardized DIN rail mounting mechanism

Applications

• Wind turbine nacelle electrical cabinets
• Converter system enclosures
• Main control boxes for pitch control systems
• Industrial automation equipment housings

Procurement Notes

Verify the specific voltage rating (e.g., AC 230 V) against your system requirements, as certification details may vary by voltage configuration. Confirm that the installation environment allows for horizontal mounting and meets the specified operating temperature range of -45°C to +70°C. Ensure the enclosure provides adequate clearance for airflow and complies with IP20 protection standards.

Selection Notes

Select this model when active heating with forced air circulation is required for medium-sized enclosures. It is suitable for applications where space constraints favor DIN rail mounting over panel mounting. Consider the power output relative to the cabinet volume and external temperature conditions to ensure adequate heat dissipation during cold weather operation.

Part Context

This component belongs to the Stego HV series of fan heaters, specifically engineered for industrial and renewable energy applications. The HV 031 variant is part of a broader portfolio including temperature controllers and ventilation filters, providing comprehensive thermal management solutions for sensitive electronic equipment in harsh environments.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Verify compatibility based on mounting dimensions, electrical connections, and thermal output. Alternative Stego models such as HVL031 series variants may offer similar functionality but require verification of specific technical parameters.
