Single-phase transformer STM 400VA 230/230V IP00 isolation or safety transformer with single-chamber housing 16252-9908

Single-phase transformers STM – safety and reliability in your installation

The STM 400VA 230/230V single-phase transformer is an ideal solution for both professional installers and end-users looking for a reliable and safe power source. The device is designed for general applications, integration into industrial and electrical installations. It provides galvanic isolation of circuits, protecting against electric shock and interference.

Construction and application

The STM transformer is manufactured in accordance with EN 61558-2-4 and EN 61558-2-6 standards, which guarantees its compliance with European safety standards. Its construction is based on insulation class B (130°C), which ensures thermal resistance and long-term operation at an ambient temperature of up to 40°C. The IP00 protection class means that the transformer requires installation in a protected housing or distribution cabinet. Thanks to its compact dimensions (120 mm width, 103 mm depth and 125 mm height), it can be easily integrated with various systems.

The device is perfect for anywhere where galvanic isolation between the primary and secondary circuits is required – for example, in control systems, lighting or powering electronic devices. This is particularly important in industrial environments where safety is paramount.
