Mean Well SI06W8-03 8:1 Ultra-Wide Input DC-DC Regulated Converter, Single Output 6W 3.3V 5mA

The SI06W8-03 is a regulated DC-DC converter intended for applications that need a stable 3.3V DC output from a very wide DC input range. Its 6W power rating and compact 1 inch by 1 inch DIP package make it relevant for space-constrained industrial and embedded power designs.

This model stands out for its 8:1 ultra-wide input range, which gives it more flexibility than converters built for narrower input windows. It also combines 3KVDC input-to-output isolation, no minimum load requirement, and protection features in a compact industry-standard package.

The SI06W8-03 provides a single regulated 3.3V output with a 6W power rating. It is designed as a single-output converter for systems that require low-voltage DC power with regulation.

Yes. Mean Well specifies an operating temperature range of -40°C to +90°C for this model, which supports use in demanding industrial environments. That range makes it better suited to temperature-variable applications than many general-purpose converters.

This converter includes protection for short circuit, overload, over temperature, over voltage, and input under voltage. It also offers up to 86% efficiency, 3KVDC I/O isolation, and a 3-year warranty, which helps support reliability in long-term use.
