It features an input voltage of 400V and an output voltage of 230V with a power rating of 100VA. Operating at a frequency of 50-60 Hz, this transformer is ideal for industrial and control applications requiring reliable galvanic isolation and stable power supply for sensitive equipment.

## Long description

The Eaton STI0,1 isolation transformer is a robust single-phase unit engineered for precise voltage conversion in industrial and control environments. With an input voltage of 400V and an output of 230V, this 100VA transformer provides essential galvanic isolation, ensuring that sensitive electronic equipment remains protected from electrical interference and voltage fluctuations. Its compact design and adherence to international safety standards make it a reliable component for maintaining stable power distribution in various control systems.
Advantages
This transformer offers exceptional operational reliability due to its high-quality construction and compliance with rigorous IEC and VDE standards. The galvanic isolation feature significantly enhances safety by decoupling the output circuit from the input supply, which is critical for preventing electrical hazards in complex control panels. Its efficient design supports a short-time rating of 0.24 kVA, providing the necessary flexibility for applications with varying power demands while maintaining consistent performance across a standard frequency range of 50 to 60 Hz.
Suitable for
Industrial control panels and automation systems
Galvanic isolation for sensitive electronic instrumentation
Safety-critical power supply applications
Voltage conversion in machinery and equipment
When it may not be suitable
This unit is not designed for outdoor use or environments where it may be exposed to moisture, dust, or corrosive elements, as it features an IP00 degree of protection. It is also not intended for high-power applications exceeding its rated capacity of 100VA for continuous operation.
Key specifications
Rated power: 0.1 kVA
Short-time rating: 0.24 kVA
Input voltage: 400V (+/- 5%)
Output voltage: 230V
Frequency: 50-60 Hz
Degree of protection: IP00
Dimensions: 85 mm x 89 mm x 91 mm
How to use
Installation should be performed by qualified personnel in accordance with local electrical regulations and the provided technical documentation. The transformer must be mounted within a protective enclosure to compensate for its IP00 rating. Ensure that the input and output terminals are connected securely according to the wiring diagram, maintaining proper ventilation around the unit to prevent overheating during operation. Verify that the input voltage matches the 400V specification before energizing the system.
What to consider before purchase
