The VMS-200C-48-CNF from CUI Inc. is an AC/DC converter that delivers a nominal 48 Vdc output at up to 4.16 A, with maximum output power of 200 W. It operates from 85 to 264 Vac or 120 to 370 Vdc input and accepts line frequencies from 47 to 63 Hz. Typical efficiency is 94% at 230 Vac, with power factor correction typical values of 0.99 at 115 Vac full load and 0.95 at 230 Vac full load.
The converter provides a maximum input current of 3.0 A at 115 Vac and 2.0 A at 230 Vac. Cold-start inrush current is limited to 40 A at 115 Vac and 75 A at 230 Vac, while leakage current is 0.1 mA maximum at 240 Vac. No-load power consumption is 0.5 W maximum. Output ripple and noise are 100 mVp-p maximum at full load, initial set-point accuracy is ±1%, and line and load regulation are both ±0.5%.
Hold-up time is at least 12 ms at 230 Vac and 25°C. The regulated 48 Vdc output and 200 W rating make the converter suitable for applications requiring a single 48 V power rail, including industrial and distributed power systems where a wide input range is needed.
