Product Description
Product Overview
The Belfuse A41 Series All-4-One International Transformers are designed to provide high isolation, creepage, and clearance to comply 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 configurable for series or parallel operation. Terminals are of the solder lug / quick connect type. The series meets UL 60601-1 and IEC/EN 60601-1 leakage current requirements and utilizes Class F (155 C) insulation. Bobbin and shroud materials meet UL 94-V0 flammability rating. Custom versions are available upon request.
