Single-phase transformer STM 630VA 230/230V IP00 isolation or safety transformer with single-chamber housing 16253-9999

Single-phase transformer – reliable power and safety

This STM single-phase transformer with a power of 630VA and a voltage of 230/230V is a solid solution for a wide range of applications. Designed as an isolation transformer, it provides galvanic isolation between the primary and secondary circuits, which increases safety and protects sensitive devices. Its construction makes it ideal for both industrial installations and electrical equipment.

Design and application

The STM transformer is characterized by an open construction with a single-compartment housing. Manufactured in accordance with EN 61558-2-4 and EN 61558-2-6 standards, it meets stringent requirements for safety and reliability. Insulation material class B (130°C) ensures long-term and stable operation even at elevated ambient temperatures (up to 40°C). This makes the transformer suitable for various working conditions.

• Galvanic isolation: Provides protection against electric shock and reduces electromagnetic interference.
• Versatility: Suitable for embedding in industrial installations, electrical equipment and other applications requiring a stable power supply.
• Durability: Made of high-quality materials guarantees long life and reliability.
• Compliance with standards: Meets the requirements of European standards EN 61558-2-4 and EN 61558-2-6, which confirms its safety and quality.

Key technical features

The dimensions of the transformer are 150 mm (width) x 120 mm (height) x 155 mm (depth), and its weight is 8.3 kg. The degree of protection IP00 means there is no protection against the ingress of solids or water - therefore, the transformer is intended for installation in dry and closed rooms. The lack of PCB mounting capability and the EI-shaped core construction affect its versatility in various installation configurations. The primary and secondary voltage is 230V, making it compatible with most standard electrical networks.
