## Long description

The BREVE STM 400VA is a robust single-phase safety transformer engineered for reliable performance in industrial and general electrical environments. This unit provides efficient voltage conversion from a 400V primary input to a 230V secondary output, ensuring stable power delivery for various connected devices. Designed as an open-type transformer with an IP00 protection rating, it is intended for integration into controlled environments such as electrical cabinets or specialized protective enclosures.
Advantages
This transformer offers exceptional operational reliability due to its high-quality construction and precise engineering. By providing effective electrical isolation, it enhances the safety of power systems and protects sensitive equipment from voltage fluctuations. Its compact design allows for efficient space utilization within control panels, while the standardized voltage transformation makes it a versatile component for diverse industrial applications requiring consistent power conversion.
Suitable for
Industrial control panels and automation systems
General electrical power distribution
Equipment requiring electrical isolation
Voltage conversion in machinery
This transformer is not suitable for outdoor use or environments exposed to moisture, dust, or direct physical contact, as the IP00 rating provides no protection against these elements. It must be installed within a secondary enclosure to ensure user safety and prevent accidental contact with live components.
Key specifications
Power rating: 400VA
Primary voltage: 400V
Secondary voltage: 230V
Protection rating: IP00
Phase: Single-phase
Installation should be performed by qualified personnel in accordance with local electrical regulations. The transformer must be mounted securely within a protective enclosure that provides the necessary degree of protection against environmental factors and accidental touch. Ensure that the ventilation within the enclosure is sufficient to dissipate heat generated during operation, maintaining the ambient temperature within the specified limits for the device.
What to consider before purchase
Ensure the enclosure provides adequate protection for an IP00 rated device
Verify that the power rating of 400VA meets your specific load requirements
Confirm that the input and output voltages match your system configuration
Check available space in your electrical cabinet for mounting
For optimal performance and longevity, ensure the transformer is installed in a clean, dry environment with adequate airflow. Regularly inspect electrical connections to ensure they remain tight and free from oxidation.
