Eaton S20N08A82N Single Phase Control Transformer

Eaton S20N08A82N is a 0.100 kVA (100 VA) single-phase control transformer. Its primary winding accepts 240 VAC or 480 VAC input, while the secondary provides 24 VAC and 48 VAC outputs. This transformer is designed for control-circuit service, delivering power to relays, contactors, timers, PLC input modules, and other low-voltage control devices in electrical panels and automation equipment. With a 100 VA rating, it can supply multiple small loads from a single source—subject to not exceeding the secondary rating. Typical installations include machine control panels, automation cabinets, conveyor systems, and HVAC control circuits where a separate low-voltage supply is required. Model S20N08A82N is manufactured by Eaton and aligns with standard control-transformer applications that derive low-voltage power from a 240/480 V supply. The 24/48 V secondary arrangement supports distributing control power to devices at two common voltages from one transformer. To ensure proper performance, ensure the combined load on the 24 V and 48 V outputs does not exceed 100 VA.
