Single-phase transformer STM 250VA 400/230V IP00 isolation or safety transformer with single-chamber housing 16252-9911

Separation transformer STM 250VA 400/230V – a reliable source of safe power

This single-phase STM separation transformer with a power of 250VA and a voltage of 400/230V is a solid solution for applications requiring galvanic isolation and protection against electric shock. Designed for both industrial installations and electrical equipment, it provides safe and stable power. The single-compartment housing construction increases its durability and simplifies installation.

Construction and application

STM series transformers from BREVE-TUFVASSONS are open devices designed for integration into various installations. Designed with economy and modernity in mind, they find wide application in industrial equipment and electrical systems. Thanks to insulation class B (130°C) and compliance with EN 61558-2-4 and EN 61558-2-6 standards, they guarantee long-term and safe operation at an ambient temperature of up to 40°C. This model is particularly useful where separation of electrical circuits is required, e.g. in workshops, laboratories or when powering medical devices.

Key features and benefits

• Galvanic isolation: Provides isolation of the primary and secondary circuits, minimizing the risk of electric shock and electromagnetic interference.
• Safety: Insulation material class B and the safety transformer design (although it is not an autotransformer) increase the level of safety.
• Dimensions: Compact dimensions (96 x 100 x 114 mm) allow for easy integration with existing installations.
• Durability: Manufactured in accordance with European standards ensures high quality and reliability of the device.
• Versatility: Suitable for a wide range of applications – from powering electronic devices to securing electrical installations.
• Voltages: Adapted to work with a primary voltage of 400V and a secondary voltage of 230V, making it compatible with most electrical networks.
• Protection degree IP00: Means no protection against the ingress of solids or liquids – the transformer is intended for mounting in enclosures or dry rooms.

The STM 250VA transformer is a solid choice for professionals looking for a reliable solution for separating electrical circuits and for end-users who value safety and stable power supply.
