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 various applications requiring reliable power conversion. They feature dual primaries (115/230 V - 50/60 Hz) and dual secondaries configurable for series or parallel operation. Terminals are of the solder lug/quick connect type, and current leakage meets UL 60601-1 and IEC/EN 60601-1 standards. Insulation is Class F (155 C) and bobbin/shroud material meets UL 94-V0 flammability rating. Custom versions are available upon request.
