The VMS-180C-12 from CUI Inc. is an open-frame AC/DC converter designed for medical and industrial applications. It provides a single regulated output of 12Vdc at up to 15A, with 180W maximum output power. The converter accepts a universal AC input from 85 to 264 Vac or a DC input from 120 to 370 Vdc, operating at 47 to 63 Hz. Active power factor correction (PFC) ensures a typical power factor of 0.99 at 115 Vac and 0.95 at 230 Vac, meeting harmonic distortion requirements. Efficiency reaches 93% typical at 230 Vac, and no-load power consumption is below 0.5W. The VMS-180C-12 includes comprehensive protections: over voltage (16-60Vdc), over current (110% min), short circuit (continuous hiccup mode with auto recovery), and over temperature (auto recovery). Line and load regulation are each ±0.5%. Output ripple and noise is 60 mVp-p maximum at full load. The converter is certified to IEC 60601-1 (medical), IEC 60335-1 (household), and IEC 61558 (safety isolating transformer) standards, with CE and cURus approvals. It can be used in Safety Class I or II installations. The open-frame package measures 101.6 x 50.8 x 25.4 mm (4.00 x 2.00 x 1.00 inches) and is chassis mountable. Operating temperature range is -40°C to 70°C with derating. The output voltage is adjustable between 11.8Vdc and 12.6Vdc via an internal trim pot.
The output voltage is 12 Vdc nominal, adjustable from 11.8 to 12.6 Vdc, with a maximum output current of 15 A and output power of 180 W.
The AC input range is 85 to 264 Vac, and the DC input range is 120 to 370 Vdc, with a frequency of 47 to 63 Hz.
