RS PRO Enclosed Auto-Transformer 250 VA, 240 V AC Primary, 115 V AC Secondary, Wall Mount, Terminal Block 504-199

The RS PRO 504-199 Enclosed 250 VA Auto-Transformer is designed to deliver efficient and reliable voltage transformation in industrial, laboratory, and commercial environments. Featuring a primary voltage of 240 V AC and a secondary voltage of 115 V AC, it is ideal for powering equipment that requires a different operating voltage, such as US-standard machines on European voltage supplies.

This transformer is fully enclosed, offering superior protection against electrical interference, and includes a varnish-impregnated coil for increased dielectric strength. Its compact and robust construction allows for wall mounting, chassis mounting, or floor-standing flexibility, making it suitable for a wide range of installation scenarios. The terminal block termination comes with a protective cover to ensure safe and secure electrical connections.

The RS PRO autotransformer is engineered for high performance with a power rating of 250 VA, supporting an operating frequency range of 50 to 60 Hz. It has undergone extensive electrical and flash testing to guarantee safe operation under high voltage conditions. With compact dimensions (81 mm length, 136 mm width, 100 mm depth) and an 8.8 kg gross weight, it provides a stable footprint in industrial panels.

Designed for high thermal endurance, the transformer operates safely up to 105°C. Its construction adheres to international standards, including IEC, CE, and RoHS, certifying its compliance with safety and environmental requirements. It does not provide primary-to-secondary isolation, making it suitable for applications such as induction motor starting and transmission line voltage regulation.

Use cases include voltage reduction for imported equipment, laboratory power supply conversion, industrial machinery integration, and safe voltage regulation in manufacturing or HVAC settings. The transformer’s secure enclosure and tested reliability make it an excellent choice for demanding environments.
