## Long description

The BREVE STM 400VA is a professional-grade single-phase safety transformer engineered for secure voltage conversion and galvanic isolation. With a power capacity of 400VA and a 230/230V transformation ratio, this unit is designed to maintain electrical integrity in demanding industrial environments. Its robust construction ensures reliable performance, protecting sensitive equipment from electrical disturbances while providing a stable power supply for various professional applications.
Advantages
This transformer offers exceptional operational reliability due to its high-quality winding materials and durable core design. By providing effective galvanic isolation, it significantly enhances safety by separating the primary and secondary circuits, which helps prevent electrical shocks and reduces the risk of interference in complex control systems. The compact and sturdy build allows for efficient integration into electrical cabinets and machinery, ensuring long-term stability even under continuous load conditions.
Suitable for
Industrial control systems and automation equipment
Powering professional electrical tools and machinery
Galvanic isolation in sensitive electronic circuits
Applications requiring a stable 230V supply from a 230V source
This transformer may not be suitable for applications requiring a different voltage output, such as stepping down to 24V or 110V, as it is strictly a 230/230V unit. It is also not intended for high-frequency power electronics or applications exceeding its 400VA power rating, as overloading the device can lead to overheating and potential failure.
Key specifications
Power rating: 400VA
Input voltage: 230V AC
Output voltage: 230V AC
Phase: Single-phase
Function: Safety and galvanic isolation
Installation should be performed by qualified personnel in accordance with local electrical regulations. The transformer must be mounted in a well-ventilated area to allow for proper heat dissipation during operation. Ensure that the input and output connections are securely fastened and that the device is protected by appropriate circuit breakers or fuses on both the primary and secondary sides to prevent damage from short circuits or overloads.
What to consider before purchase
Verify that the 400VA power rating is sufficient for your connected equipment load
Ensure the installation environment provides adequate space and ventilation
Confirm that your system requires a 1:1 voltage transformation ratio
Check compatibility with existing mounting hardware in your electrical cabinet
Usage recommendations: Regularly inspect the terminal connections for tightness and ensure the transformer housing remains free of dust and debris to maintain optimal cooling efficiency. Do not exceed the rated power capacity to ensure the longevity of the unit.
