Product information

Description

The Eaton STI0,4 is a high-quality single-phase isolation transformer engineered for precise voltage conversion from 400V to 230V. Designed for industrial and commercial environments, this unit provides essential galvanic isolation, which enhances safety by decoupling the output circuit from the input power source. Its robust construction and adherence to international standards ensure reliable performance and stable power delivery for sensitive electrical equipment.

Advantages

This transformer offers significant benefits in terms of operational safety and electrical stability. By providing galvanic isolation, it effectively protects connected devices from voltage spikes and interference originating from the main power grid. The unit is built to withstand demanding conditions, featuring a durable design that supports both continuous operation and short-time power requirements. Its compact dimensions allow for efficient integration into control panels and electrical cabinets where space is limited.

Suitable for

Industrial control systems
Commercial power distribution
Galvanic isolation of sensitive electronic equipment
Voltage conversion in machinery

When it may not be suitable

This transformer is not intended for outdoor use without an appropriate protective enclosure, as it has an IP00 degree of protection. It is also not suitable for applications requiring three-phase power conversion or for loads exceeding its rated power capacity of 0.4 kVA.

Key specifications

Rated power: 0.4 kVA
Short-time rating: 1.1 kVA
Input voltage: 400V (+/- 5%)
Output voltage: 230V
Frequency: 50-60 Hz
Degree of protection: IP00
Dimensions: 121 mm x 100 mm x 131 mm

How to use

Installation should be performed by a qualified electrician in accordance with local electrical regulations and the provided technical documentation. The transformer must be mounted within a suitable protective housing or electrical cabinet to ensure safety, given its IP00 rating. Connect the 400V input supply to the primary terminals and the 230V load to the secondary terminals, ensuring that all connections are secure and properly tightened. Verify that the input voltage is within the specified tolerance range before energizing the system.

What to consider before purchase

Ensure the total power consumption of your connected devices does not exceed the 0.4 kVA continuous rating.
Confirm that the installation environment provides the necessary protection against dust and moisture.
Check that the available mounting space accommodates the physical dimensions of the unit.

Usage recommendations

Always verify that the input voltage matches the transformer's rated input before connection. Ensure adequate ventilation around the unit to prevent overheating during operation.
