HW-AC-MOD-7W-05
7 W high-efficiency AC-DC converter power supply module with universal mains input and 5 V output for industrial use.
The HW-AC-MOD-7W-05 is a Hawun AC-DC converter power supply module that delivers 7 watts at 5 volts from a universal mains input covering 85 to 264 volts AC, in a compact board-level package for industrial applications. It converts mains power into a regulated low-voltage rail directly on the board, which suits embedded and instrument products that need a small, efficient supply without a separate adapter. The universal input covers the common worldwide mains range, so one design serves several markets, and the switching conversion delivers high efficiency and a small size compared with a linear supply. Because the supply is connected to the mains, its isolation and its creepage and clearance are safety-critical, and the input protection and the filter must be chosen for the application and the standard. Its switching noise must also be managed, and a sensitive rail can be post-regulated. Every device is factory-traceable and ships with an import declaration, a certificate of origin and RoHS documentation. BeiLuo holds this part in regional stock and our FAE team supports supply selection, input protection and thermal design.
FAE Professional Review
This is the compact board-level supply we recommend when a product needs a small 5 volt rail from the mains without an external adapter. The universal input simplifies worldwide products, and the module is easy to place. Because it connects to the mains, treat the isolation and the creepage as safety-critical, and manage the switching noise with the recommended input filter and, where needed, a post-regulator for a sensitive rail.

Frequently Asked Questions
What safety points matter for a mains module?
Isolation, creepage and clearance are safety-critical, and the input protection and the fuse must be chosen for the application and the standard the product must meet.
Our FAE team helps with the safety design during design-in.
How do I reduce the switching noise?
Use the input filter the datasheet recommends, keep the switching loop small, and post-regulate a sensitive rail with a linear regulator or a low-noise converter.
Layout and filtering decide the noise.
