RS PRO Toroidal Transformer 230 V ac to 2 x 25 V ac Dual Output 225 VA 671-9173

RS PRO model 671-9173 is a high-quality toroidal transformer designed with a 230 V ac primary voltage and dual secondary outputs of 2 x 25 V ac. It delivers a rated power of 225 VA, supporting various electrical and electronic applications requiring stable and low-noise voltage transformation.

This Toroidal Transformer features an open wound design with dual 115 V ac primary windings suitable for operation at standard mains frequencies of 50 Hz and 60 Hz. The twin secondary windings allow flexible configurations - either in series, parallel, or individually - to meet diverse voltage output requirements.

The compact and lightweight construction, with a diameter of 120 mm and height of 50 mm, provides easy integration into electrical assemblies while minimizing electromagnetic interference. Copper conductor terminations ensure strong and reliable electrical connections, and the primary leads are double insulated for enhanced electrical safety.

Compared to traditional stacked lamination transformers, this toroidal variant produces extremely low radiated magnetic fields and minimal hum noise, making it suitable for sensitive electronic equipment and power supplies in industrial, laboratory, manufacturing, and HVAC applications.

Weighing approximately 2.3 kg, this transformer is easy to handle and mount. It comes shipped without mounting hardware, which can be sourced separately. Users should take care to avoid simultaneous contact of both ends of the fixing bolt with the metal chassis to prevent dangerous shorted-turn conditions.

Features a dual 115 V ac primary winding suitable for 50/60 Hz operation. Compact open wound toroidal design offers low weight and reduced electromagnetic interference. Extremely low levels of radiated magnetic fields and minimal induced noise.

The transformer has twin secondary windings configurable in series, parallel, or independent use. Primary leads are double insulated for enhanced safety. Termination is via copper conductor for reliable connections. Dimensions include 120 mm diameter and 50 mm height for easy integration.

Operates efficiently within frequency range of 50 Hz to 60 Hz. Gross weight is 2.3 kg, supporting easy mounting and handling. Ideal for electronic component, power supply and transformer applications in industrial and commercial settings.
