The Aimtec AMESR-3-12S277NZ is a board-mount AC/DC converter designed to deliver a single 12V output at 0.25A with a total power rating of 3W. It features a wide universal AC input range of 85 to 305 VAC, making it suitable for global applications, and also accepts a DC input of 70 to 430 VDC.
This converter offers an efficiency of 73% and is designed for reliable operation over an extended temperature range of -40°C to 85°C, with derating applied at higher temperatures. The compact package measures 16.1mm in length, making it suitable for space-constrained designs.
Typical applications include industrial control systems, instrumentation, and embedded electronics where a regulated low-power isolated supply is required. The single-output design simplifies integration into systems needing a 12V rail.
The output voltage is 12 VDC and the output current is 0.25 A.
The AC input voltage range is 85 to 305 VAC, and the DC input voltage range is 70 to 430 VDC.
The operating temperature range is -40°C to 85°C with derating.
The power rating is 3 watts.
