Product Description
Product Overview
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 configurable for series or parallel operation. Terminals are of the solder lug / quick connect type. 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.
