The VMS-200C-15-CNF is a 200W AC/DC converter manufactured by CUI Inc. This off-board power supply delivers a nominal 15V DC output capable of sourcing up to 13.3A. The unit operates with a typical efficiency of 93% when connected to a 230 Vac line. It accepts a universal AC input ranging from 85 to 264 Vac at frequencies between 47 and 63 Hz. Input current draws peak at 3.0A under 115 Vac conditions and 2.0A under 230 Vac conditions. Cold start inrush current reaches 40A at 115 Vac and 75A at 230 Vac.
Design engineers should account for the specified inrush characteristics when sizing upstream fuses or circuit breakers. The datasheet explicitly warns that adjusting the output voltage requires care to avoid exceeding the rated 200W power limit or 13.3A current threshold. While the nominal output is listed as 15V, technical specifications indicate adjustable operational windows spanning 11.8 to 12.6 Vdc and 14.7 to 15.8 Vdc.
This converter is suited for applications requiring robust, regulated DC power within standard industrial and commercial enclosures. Its wide input voltage tolerance allows deployment across global mains standards without external transformers. Proper ventilation must be maintained to sustain the 93% efficiency rating and prevent thermal derating during continuous operation.
