Single-phase transformer STM 160VA 230/24V IP00 isolating or safety transformer with single-chamber housing 16224-9922

Safety and Isolation Transformer – Reliability in a Compact Housing

This single-phase STM transformer with a power of 160VA and a voltage of 230/24V is a solid solution for a wide range of applications. Designed for both installers and end-users, it provides safe and efficient power supply for devices. The single-compartment housing design simplifies installation and protects against accidental contact.

Features and Application

The STM transformer is a safety or isolation device, which means it effectively isolates the secondary circuit from the primary circuit, minimizing the risk of electric shock. It is ideal for use in industrial installations, electrical equipment, and anywhere where protection against short circuits and overloads is required. Insulation class B (130°C) guarantees long-lasting and reliable operation even at elevated ambient temperatures (up to 40°C). Thanks to its compact dimensions (96 x 87 x 114 mm), the transformer easily integrates into existing infrastructure.

• Safety first: Designed as a safety transformer, it provides protection against electric shock.
• Versatile application: Suitable for industrial installations, electrical equipment and other applications requiring galvanic isolation.
• Durable construction: Insulation class B and IP00 protection rating ensure reliability and long life.
• Compact dimensions: Facilitate installation even in limited space.
• Compliance with standards: Manufactured in accordance with EN 61558-2-4 and EN 61558-2-6 confirms the high quality and safety of the device.

Technical parameters and construction

The STM transformer is characterized by a solid construction based on an EI-shaped core. Its rated power is 160 VA, and the primary voltage is 230 V AC. The secondary voltage is 24 V AC, making it suitable for powering many popular low-voltage devices. The IP00 degree of protection indicates no protection against the ingress of solids and water – therefore, the transformer is intended for installation in dry and well-ventilated places. It is made in Class I insulation, which means it has a protective earth connection.

STM transformers manufactured by Breve Tufvassons Sp. z o.o. are valued for their reliability and durability, and their construction meets the latest safety standards.
