It features a robust construction for reliable performance in demanding environments.

## Long description

The BREVE STM 100VA isolation transformer is a professional-grade single-phase device engineered to provide secure galvanic separation between electrical circuits. Operating with a power rating of 100VA and a 230V/230V voltage ratio, this unit is specifically designed to enhance electrical safety and minimize interference in sensitive electronic systems. Its robust construction ensures consistent performance and durability, making it a reliable component for industrial and technical environments where circuit isolation is essential for operational stability.
Advantages
This isolation transformer offers significant benefits by effectively decoupling circuits, which helps in preventing electrical shocks and reducing the impact of ground loops or power line noise. The high-quality build ensures long-term reliability even in demanding professional settings. By maintaining a stable 230V output from a 230V input, it provides a secure power source that protects connected equipment from common electrical disturbances and surges, thereby extending the lifespan of sensitive electronic components.
Suitable for
Industrial control systems requiring galvanic isolation
Professional electronic testing and measurement setups
Medical or laboratory equipment where electrical safety is critical
Protection of sensitive automation components from power interference
When it may not be suitable
This transformer is not intended for applications requiring voltage transformation, such as stepping up or stepping down voltage levels, as it maintains a 1:1 ratio. It is also not suitable for high-power industrial machinery that exceeds its 100VA capacity.
Key specifications
Power rating: 100VA
Input voltage: 230V AC
Output voltage: 230V AC
Phase: Single-phase
Function: Galvanic isolation
How to use
The transformer should be installed by a qualified professional in a dry, well-ventilated area. Connect the primary side to the 230V power source and the secondary side to the equipment requiring isolation. Ensure that all wiring connections are secure and comply with local electrical safety standards. Proper grounding of the transformer housing is recommended to maintain optimal safety and performance levels.
What to consider before purchase
Verify that the 100VA power rating is sufficient for your specific load requirements
Ensure the installation environment is free from excessive moisture or extreme temperatures
Confirm that the 230V/230V configuration matches your equipment needs
Usage recommendations
Always verify that the total power consumption of the connected devices does not exceed the 100VA limit to prevent overheating and ensure the longevity of the transformer.
