Single-phase transformer TMM 100VA 400/230V IP00 isolating or safety transformer with a two-chamber housing. 16252-9983

Single-phase transformers – safety and reliability in your installation

This TMM single-phase transformer with a power of 100VA and a voltage of 400/230V is a solid solution for separation and safety applications. Designed for installation in electrical installations and industrial devices, it provides stable power and protection against short circuits and overloads. Manufactured in accordance with EN 61558-2-4 and EN 61558-2-6 standards, it guarantees compliance with applicable standards.

Design and application

The TMM transformer is characterized by a separation design, which means that the primary and secondary circuits are galvanically isolated. This is crucial for ensuring the safety of users and protecting sensitive devices. This minimizes the risk of electric shock and electromagnetic interference. The two-compartment housing further increases safety by protecting against accidental contact with live parts. The rated apparent power of 100 VA makes the transformer ideal for applications requiring a stable power supply of medium power.

Key features and benefits

• Galvanic isolation: Provides a high level of safety for users and protects connected devices.
• Two-compartment housing: Additional protection against contact with live parts, increasing the safety of the installation.
• Compliance with standards: Meets the requirements of EN 61558-2-4 and EN 61558-2-6 standards, guaranteeing reliable operation and safety of use.
• Insulation class B: Allows operation in ambient temperature up to 40°C, providing a wide range of applications.
• Dimensions: Compact dimensions – width 84 mm, height 74 mm, depth 100 mm – make it easy to install even in limited space.
• Voltages: Adapted to work with a primary voltage of 400V and a secondary voltage of 230V – typical values in most electrical installations.
• Protection degree IP00: Means no protection against access to live parts and against the influence of the external environment – the transformer is intended for mounting inside enclosures or electrical cabinets.

The TMM transformer is a reliable solution for both professional installers and end-users looking for a safe and effective way to separate electrical circuits or provide safe power to devices. Its solid construction and compliance with applicable standards guarantee long-term and trouble-free operation.
