BREVE TMM 400VA Single-Phase Transformer 400/230V

The BREVE TMM 400VA is a professional-grade single-phase safety transformer engineered for reliable voltage conversion in industrial and control applications. With a power rating of 400VA and a transformation ratio of 400V to 230V, this unit provides essential electrical isolation and stable power delivery for sensitive equipment. Its robust construction ensures long-term durability and consistent performance in demanding electrical environments.

Advantages

This transformer offers exceptional operational reliability due to its high-quality winding materials and core design. It provides effective galvanic isolation, which enhances safety by separating the primary and secondary circuits. The compact design allows for efficient integration into control cabinets and machinery, while the high thermal stability ensures that the unit maintains performance even during continuous operation.

Suitable for

• Industrial control systems
• Power supply for automation equipment
• General electrical isolation tasks
• Voltage adaptation in machinery

This transformer may not be suitable for applications requiring power outputs exceeding 400VA, as overloading can lead to overheating and potential failure. It is also not intended for high-frequency power electronics or environments with extreme moisture or corrosive atmospheres without additional protective housing.

Key specifications

• Power rating: 400VA
• Primary voltage: 400V
• Secondary voltage: 230V
• Phase: Single-phase
• Design: Safety transformer

How to use

Installation should be performed by qualified electrical personnel in accordance with local safety regulations. The transformer must be mounted in a well-ventilated area to allow for proper heat dissipation. Connect the primary 400V supply to the designated input terminals and the secondary 230V load to the output terminals, ensuring that all connections are tightened securely and that the circuit is properly fused 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 total load requirements.
• Ensure the input voltage matches your local power grid configuration.
• Check the available space in your enclosure for mounting dimensions.
• Confirm that the environmental conditions meet the manufacturer's operational standards.

Usage recommendations

Always ensure that the transformer is installed with appropriate circuit protection devices to safeguard against electrical faults and to extend the service life of the unit.
