Auto-Transformers Give American Appliances A Passport

Foster’s latest line of Auto-Transformers, or autoformers, allow North American appliances that operate from a 120V source to work virtually anywhere in the world. The components employ a single non-isolated winding to step up or step down the available line voltage. The autoformers are UL/C-UL recognized (file E19598), and TUV certified to EN60950-1 (Certificate R72050845).  They deliver an output rated at 115V at 1500 VA.  Input voltage taps of 100V, 115V, 127V, 200V, 220V, 230V, and 240V at 50/60 Hz are standard.  They can also be wired in parallel for increased capacity.  UL recognized Class 180 (H) insulation is used and optional resettable thermal overload protection is also available to protect against overheating.
