Whether we're talking about a transformer, a transformer, or a step-up transformer, we're talking about a component for converting alternating current (AC). The operating principle is simple: Two coils are plugged onto a common magnetic core. The input voltage (e.g., 230VAC) is applied to the primary coil, and the output voltage (e.g., 12VAC) is tapped off the secondary coil. The coils are not connected (galvanically isolated); power is transferred via electromagnetic induction. Selecting the right AC/AC transformer is crucial for achieving the best results during installation and operation. ProConnecting offers numerous application-specific step-up transformers from Breve. Top-hat rail AC/AC transformers are ideally suited for mounting on standard TS35/TH35 DIN rails. With apparent power ratings from 10VA to 100VA and output voltages such as 12VAC and 24VAC, a wide range of loads can be reliably supplied. Breve's single-phase AC/AC transformers also impress with high performance at an affordable price. The Breve STM series transformers are ideal for use in electrical installations. Even demanding devices can be operated with ease thanks to apparent power ratings of up to 2,500 VA. The Breve TTH series, on the other hand, is designed for halogen lamps. Transformers with 50 VA, 105 VA, or 150 VA ensure the supply of a wide variety of lighting systems.
