## Summary description

The Eaton STI0,5 is a single-phase isolation transformer designed for safe electrical separation. It features an input voltage of 400V and an output voltage of 230V with a power rating of 500VA. Operating at a frequency of 50-60 Hz, this transformer is ideal for industrial applications requiring reliable voltage conversion and galvanic isolation to protect sensitive equipment and ensure operational safety.

## Long description

The Eaton STI0,5 is a high-quality single-phase isolation transformer engineered to provide reliable electrical separation and voltage conversion. With a primary input of 400V and a secondary output of 230V, this unit is specifically designed to support industrial control systems and sensitive electronic equipment. It ensures operational safety by providing galvanic isolation, effectively decoupling the load from the main power supply to minimize electrical interference and protect connected devices.
Advantages
This transformer offers robust performance and high reliability in demanding industrial environments. Its design focuses on safety and efficiency, meeting rigorous international standards for control and isolation transformers. The compact construction allows for efficient space utilization within control cabinets, while the high-quality materials ensure long-term durability and consistent power delivery even under varying load conditions.
Suitable for
Industrial control panels and automation systems
Galvanic isolation of sensitive electronic equipment
Voltage conversion for machinery requiring 230V from a 400V supply
Safety-critical applications requiring electrical separation
When it may not be suitable
This transformer is not intended for outdoor use without a protective enclosure, as it has an IP00 protection rating. It is also not suitable for applications requiring power outputs exceeding its 500VA continuous rating or 1.6kVA short-time rating.
Key specifications
Rated power: 0.5 kVA
Short-time rating: 1.6 kVA
Input voltage: 400V (± 5%)
Output voltage: 230V
Frequency: 50-60 Hz
Protection degree: IP00
Dimensions: 121 mm x 120 mm x 131 mm
How to use
Installation should be performed by qualified electrical personnel in accordance with local safety regulations. The transformer must be mounted within a suitable protective enclosure to prevent accidental contact with live parts, given its IP00 rating. Ensure that the input and output terminals are connected securely according to the wiring diagram provided with the unit. Proper ventilation must be maintained around the transformer to prevent overheating during operation.
What to consider before purchase
Verify that the 500VA power rating is sufficient for your specific load requirements.
Ensure the installation environment provides adequate protection against dust and moisture.
Confirm that the input voltage matches your local power supply specifications.
Usage recommendations
Always ensure that the transformer is properly grounded and that the connected load does not exceed the specified continuous power rating to maintain optimal performance and safety.
