Product Description
Product Overview
The Belfuse A41 Series All-4-One International Transformers are designed to provide high isolation, creepage, and clearance, essential for complying with international safety standards. These transformers offer lower cost and improved 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, and the current leakage meets UL 60601-1 and IEC/EN 60601-1 standards. The insulation class is F (155 C), and the bobbin and shroud material meet UL 94-V0 flammability rating. These transformers are RoHS compliant and available in chassis mount configurations. Custom versions are available upon request.
