The Eaton STN0,1 is a professional-grade single-phase control transformer designed to provide reliable voltage conversion for industrial electrical systems. With a rated power of 100VA, this unit efficiently steps down a nominal input voltage of 400V to a stable 24V output. Engineered for durability and safety, it is built to meet rigorous international standards, making it a dependable component for control panels and automation equipment.

Advantages

This control transformer offers exceptional operational reliability due to its robust construction and adherence to strict safety standards such as IEC/EN 61558-2-2 and UL 506. Its compact design allows for efficient space utilization within electrical enclosures, while the high-quality winding materials ensure consistent performance even under demanding conditions. The unit is specifically designed to support long-term stability in industrial environments, minimizing the risk of voltage fluctuations in sensitive control circuits.

Suitable for

• Industrial control panels
• Automation and robotics systems
• Powering 24V control circuits
• Machine tool equipment
• Electrical distribution systems

This transformer may not be suitable for applications requiring high-power output beyond its 100VA rating or for environments where a high degree of ingress protection is required, as this unit features an IP00 rating and must be housed within a protective enclosure.

Key specifications

• Rated power: 100VA
• Short-time rating: 0.16kVA
• Input voltage: 400V (+/- 5%)
• Output voltage: 24V
• Degree of protection: IP00
• Dimensions: 85mm x 75mm x 91mm
• Standards: IEC/EN 61558-2-2, VDE 0570, UL 506

Installation should be performed by qualified personnel in accordance with local electrical regulations. The transformer must be mounted within a suitable protective enclosure to prevent accidental contact with live parts, as the unit is rated IP00. Ensure that the input and output wiring are correctly sized for the current load and that all connections are tightened securely to prevent overheating.

What to consider before purchase

• Verify that the 100VA power rating is sufficient for your specific load requirements.
• Ensure the installation environment provides adequate ventilation to manage heat dissipation.
• Confirm that the unit will be installed inside a protective cabinet to comply with safety standards.
• Check that your supply voltage remains within the specified 400V +/- 5% range.

For optimal performance and longevity, ensure the transformer is not operated continuously above its rated power capacity and that it is installed in a clean, dry environment free from excessive dust or moisture.
