Product information

Description

The Eaton STI1,0 is a professional-grade single-phase isolation transformer engineered for reliable voltage conversion and galvanic separation in electrical systems. With a rated input of 400V and an output of 230V, this unit is designed to provide stable power distribution while ensuring the safety of connected equipment. Its robust construction and adherence to international standards make it a dependable component for industrial and commercial power management.

Advantages

This transformer offers excellent operational reliability through its high-quality design and precise voltage regulation. By providing galvanic isolation, it effectively separates the input and output circuits, which helps in reducing electrical noise and protecting sensitive electronics from potential surges or ground faults. The unit is built to withstand demanding environments, offering a short-time rating of 2.8 kVA, which provides flexibility for applications with varying power requirements.

Suitable for

Industrial control panels and automation systems
Powering sensitive electronic equipment requiring galvanic isolation
Commercial electrical distribution setups
Safety-critical applications compliant with IEC/EN standards

When it may not be suitable

This transformer is not intended for outdoor use without a protective enclosure, as it has an IP00 degree of protection, meaning it is open and lacks resistance against water or dust ingress. It is also not suitable for high-power applications exceeding its 1kVA continuous rating or for use in environments where specific hazardous area certifications beyond the listed standards are required.

Key specifications

Rated power: 1 kVA
Short-time rating: 2.8 kVA
Input voltage: 400V (± 5%)
Output voltage: 230V
Frequency: 50-60 Hz
Degree of protection: IP00
Dimensions: 151 mm x 150 mm x 211 mm

How to use

The Eaton STI1,0 must be installed by a qualified electrician in accordance with local electrical codes and the provided technical documentation. Given its IP00 rating, the transformer should be mounted within a suitable electrical cabinet or enclosure that provides the necessary protection against environmental factors and accidental contact. Ensure that the input and output terminals are securely connected according to the wiring diagram, and verify that the input voltage matches the 400V specification before energizing the system.

What to consider before purchase

Ensure the installation environment provides adequate ventilation and protection from moisture or debris.
Verify that the 1kVA continuous power rating is sufficient for your specific load requirements.
Confirm that the mounting space within your enclosure accommodates the physical dimensions of the unit.

Usage recommendations

Always perform a thorough inspection of the connections and ensure the transformer is properly grounded before operation to maintain safety and performance standards.
