Compact EN55032 Class B EMC Compliant AC/DC-DC Converter with Class II Isolation for Industrial and Consumer Applications

The SWAC0TS Series is a compact, high-performance AC/DC-DC converter module designed for global applications, featuring dual wide-range AC and DC input with built-in lightning/surge protection, pulse group attenuation, and differential/common mode filters. With synchronous rectification delivering up to 88% efficiency and ultra-low no-load power consumption below 0.1W, this vacuum-potted module ensures reliable operation in harsh environments by resisting dust and moisture. Compliant with EN55032 Class B EMC and Class II isolation safety standards, it requires no peripheral circuit design and supports natural cooling, making it an ideal power solution for space-constrained applications.
