20W Wide Input range PCB Mount AC-DC Encapsulated Power Module with 4000 VAC Isolation

BFC20 Series

20W Board Mount AC to DC Industrial and ITE Power Conversion (Module) - High Efficiency, wide input range

The ARCH BFC20 is a 20W AC-DC power module designed for industrial and embedded systems, featuring a wide input range of 85–305VAC. It supports global power grids, including 277VAC applications, and ensures stable operation under high-line conditions. Compared to conventional 90–264VAC power modules, BFC20 provides greater input tolerance, reducing design limitations in real-world industrial environments.

Optimized for Real-World Application Requirements

BFC20 is engineered to meet the practical needs of most industrial applications rather than pursuing extreme specifications. It focuses on key performance factors such as wide input range, stable output, industrial-grade temperature capability, and cost efficiency. This approach allows engineers to select a power solution that fits actual system requirements without overdesign or unnecessary cost burden.

Balanced Performance, Size, and Cost Efficiency

Within the 20W class, BFC20 offers a combination of 85–305VAC input, up to 87% efficiency, 4000VAC isolation, and an operating temperature range of -40°C to +85°C, along with 5000m altitude capability. These specifications make it suitable for a wide range of industrial control boards, communication modules, and embedded systems, while maintaining strong cost competitiveness.

Reducing Overdesign and Selection Risks

For engineers, the most effective power solution is not necessarily the highest-spec one, but the one that achieves the right balance between performance, cost, and system requirements. BFC20 is positioned to deliver stable operation under typical industrial conditions, minimizing the need for additional front-end design while avoiding the cost impact of over-specified solutions.
