The Belfuse A41 Series All-4-One International Transformers are designed to provide high isolation, creepage, and clearance required for compliance with international safety standards. These transformers offer lower cost and better performance, suitable for various applications requiring robust isolation. They feature dual primaries (115/230 V - 50/60 Hz) and dual secondaries that can be configured in series or parallel. Terminals are of the solder lug/quick connect type. The current leakage meets UL 60601-1 and IEC/EN 60601-1 standards. Insulation is Class F (155 C), and the bobbin and shroud material meet UL 94-V0 flammability rating. Custom versions are available upon request.
