Single-phase transformer STM 100VA 400/230V IP00 isolating or safety transformer with single-chamber housing 16252-9917

Safety and isolation transformer STM 100VA 400/230V

This single-phase STM transformer with a power of 100VA and voltages of 400/230V is a reliable solution for applications requiring galvanic isolation and protection. Designed for both industrial installations and electrical equipment, it ensures safe and efficient operation. Its core construction increases mechanical strength and simplifies installation.

Features and application

The STM transformer is open, meaning it does not have a protective housing. This makes it ideal for embedding in devices and installations where space is limited. As an isolation transformer, it effectively isolates the primary and secondary circuits, minimizing the risk of electric shock and electromagnetic interference. Additionally, it meets the requirements of a safety transformer, which increases the level of user protection. The rated apparent power of 100 VA allows powering various devices with low power consumption.

Construction and parameters

Manufactured in accordance with EN 61558-2-4 and EN 61558-2-6 standards, the STM transformer is characterized by high quality and durability. Insulation material class B (130°C) ensures resistance to high temperatures, and class I insulation guarantees safe use. The degree of protection IP00 means there is no protection against the ingress of solids or liquids – therefore, the transformer should be mounted in a dry and well-ventilated place. The dimensions of the transformer are 84 mm wide, 75 mm high and 95 mm deep, which facilitates its integration with existing systems. The primary voltage is 400 V, and the secondary voltage is 230 V.
