The VMS-200-12 is a 200W AC/DC converter from CUI Inc. that provides a regulated 12V output at up to 16.67A. It accepts a universal input voltage range of 90 to 264 Vac at 47-60 Hz, making it suitable for global applications. The converter achieves up to 92% efficiency at full load and includes active power factor correction meeting EN 61000-3-2. It features low ripple and noise of 150 mVp-p and a hold-up time of 10 ms at 115 Vac. Protection features include over voltage protection (16 Vdc, recycle AC to restart) and under voltage shutdown (69-83 Vac). The open-frame design supports forced air or baseplate cooling to achieve full 200W output; with convection cooling, output is derated to 180W at 220 Vac. A fan output provides 12 Vdc at 300 mA for open-frame or 500 mA for covered configurations. The converter is suitable for applications requiring low leakage current (0.3 mA at 264 Vac, 0.1 mA enclosure/patient).
The input voltage range is 90 to 264 Vac.
The output voltage is 12 Vdc and the maximum output current is 16.67 A.
The minimum efficiency is 92% at full load, 25°C, 230 Vac input.
It includes over voltage protection (16 Vdc, recycle AC to restart) and under voltage shutdown (69-83 Vac).
Ripple and noise is 150 mVp-p maximum.
Hold-up time is 10 ms minimum at 115 Vac.
