Belelli 800VA 50 60Hz 0-480V Pri 0-21-110 220V Sec Transformer

Belelli 800 VA 50/60 Hz single‑phase autotransformer provides flexible voltage conversion from a common winding, enabling a 0–480 V primary input with taps for 0, 21, 110, and 220 V on the output. This multi‑tap arrangement lets equipment designed for 110/220 V be powered from higher mains by selecting the matching output tap, without isolation between windings. Rated at 800 VA, it supports modest loads in lab, workshop, or testing setups that require mixed‑voltage operation, while operating at standard line frequencies of 50 or 60 Hz. Belelli, an Italian manufacturer of transformers and related magnetics, designs such devices for configurable voltage stepping on a single winding to simplify power delivery in environments where multiple end voltages are in use. The product aligns with Belelli’s monophase transformer range and is suitable for applications that need reliable, adjustable voltage conversion without the need for separate isolation between windings.
