The SWI6D and SMI6D series prioritize energy efficiency and device protection. They feature ultra-low no-load power consumption (less than 0.1 W), which lowers operating temperatures, extends adapter life, improves system reliability and reduces total costs. The over-current and short-circuit protection keep connected devices safe from electrical issues, reducing the risk of damage and failure.

Designed for worldwide use, these adapters offer global compatibility with a universal input voltage range of 90 V AC to 264 V AC, ensuring they work seamlessly with power outlets anywhere. The fixed blade adapters (SWI6D, SWI6AD) are available with U.S., EU and U.K. blades, while the interchangeable models (SMI6D, SMI6AD) feature a variety of regional adapters (NA, EU, U.K., AU, CN) for global compatibility. To provide maximum flexibility, the series includes both corded and USB-A inlet options, accommodating a wide range of devices. There will be additional stocking units with USB-C plugs to accommodate global standardization.

“The launch of our SWI6D and SMI6D series reinforces Bel Fuse's dedication to providing advanced power solutions that directly address the evolving demands of the ITE and consumer markets,” said Gen Reguera, product manager. “Our 6W fixed and multi-blade series are engineered for deep customizability, allowing our clients to collaborate directly with Bel's technical experts to achieve optimal versatility and significant cost efficiencies within their designs.”

Engineered to meet complex performance and safety standards, the SWI6D and SMI6D series comply with Level VI energy efficiency requirements and adhere to IEC 62368-1 safety standards. The comprehensive standards mitigate potential hazards and minimize power waste, providing users with assurance of reliable, safe and sustainable operation in ITE and consumer applications.
