The CUI Inc. VMS-550C-12-CNF is an enclosed AC-DC power supply designed for various applications, including ITE (Commercial) and Medical. It features a 12Vdc output voltage with a maximum current of 41.60A, delivering up to 499.2W of power under forced air cooling.
This power supply operates with a wide input voltage range of 90-264 Vac and 127-370 Vdc, incorporating active Power Factor Correction (PFC) for improved efficiency, rated at 91.0% typical at 230 Vac.
Key features include a 3" x 5" footprint, a -40 to 70 °C operating temperature range, and protections such as over-voltage, over-current, and short-circuit protection. It is certified to 60601 safety standards and designed to meet 60335 & 61558 requirements.
The unit is chassis mountable and includes features like remote sense, standby output, and power good signal, making it suitable for demanding power conversion needs.
The input voltage range is 90-264 Vac (47-63 Hz) or 127-370 Vdc.
The output voltage is 12V nominal, adjustable from 11.4 to 12.6V, with a maximum output current of 41.6A.
The operating temperature range is -40°C to 70°C with derating.
The typical efficiency is 91% at 230 Vac.
Protection features include over voltage protection (15.6V latching), over current protection (105% hiccup auto recovery), short circuit protection (continuous auto recovery), and over temperature protection (auto recovery).
The package type is enclosed with chassis mount mounting.
The dimensions are 130.0mm x 86.0mm x 43.0mm.
