Single-phase transformer STM 400VA 400/230V IP00 isolation or safety transformer with single-chamber housing 16252-9907

Single-phase transformer for wide applications

This STM single-phase transformer with a power of 400VA and a voltage of 400/230V is a reliable solution for powering devices requiring galvanic isolation or voltage reduction. Its construction, based on an EI core, makes it ideal for use in industrial, electrical and internal device installations. Manufactured by the renowned manufacturer Breve-Tufvassons, it guarantees high quality and compliance with applicable standards.

Construction and application

The STM transformer is an open model, without a housing, designed for mounting on a flat surface. The IP00 protection class means there is no protection against the ingress of solids and water, therefore its operation requires appropriate environmental conditions. Its main task is to convert the network voltage of 400V AC to a safer 230V AC. Thanks to this, it finds application in powering various types of electrical devices, providing them with stable and safe operation. Insulation class B (130°C) ensures long-lasting and trouble-free operation even at elevated ambient temperatures (up to 40°C).

Key features and benefits

• Galvanic isolation: Ensures user safety by isolating the secondary circuit from the primary, minimizing the risk of electric shock.
• Power 400VA: Allows powering devices with a power demand of up to 400VA.
• Voltages 400/230V: Enables adaptation of the transformer to standard power networks and devices.
• Compact dimensions: Dimensions of 120 x 103 x 125 mm facilitate mounting in a limited space.
• Compliance with standards: Meets the requirements of EN 61558-2-4 and EN 61558-2-6 standards, which confirms its safety and reliability.
• Insulation class B: Guarantees resistance to high temperatures and long device life.
• Weight 4.6 kg: Facilitates transport and installation of the transformer.

This transformer is particularly recommended for installers due to its simple installation and wide range of applications. For end users, it is a reliable source of safe power for their electrical devices. Its solid construction and compliance with standards ensure long-lasting and trouble-free operation.
