The lighting transformer is the central unit of the lighting system. A total of 50 luminaires can be connected to one 1500 VA transformer in a safe 48 V low‑voltage network. The luminaires are divided into two circuits, allowing a maximum of 25 luminaires per circuit. Connection is quick thanks to the convenient spring terminals. Cable strain relief is done on the transformer bar. The luminaires are connected to a 2×2.5 mm² twisted‑pair cable, which is used as the main line for installing the 48 V luminaires. The multi‑strand 2×2.5 mm² twisted‑pair cable has a high‑quality H07V‑R coating, making it easy to handle even in cold conditions. The transformer can be mounted on the wall using the suspension loops.
