Product Overview
The Belfuse A41 Series All-4-One International Transformers are designed to provide high isolation, creepage, and clearance, ensuring compliance with international safety standards. These transformers offer lower cost and better performance, suitable for applications requiring robust isolation. They feature dual primaries (115/230 V - 50/60 Hz) and dual secondaries configurable for series or parallel operation, with solder lug/quick connect terminals. The series meets UL 60601-1 and IEC/EN 60601-1 leakage current requirements and boasts Class F (155 C) insulation. Bobbin and shroud materials meet UL 94-V0 flammability rating. Custom versions are available upon request.
