The VOF-225A-58-1 from CUI Inc. is an open-frame AC/DC converter designed for efficient power conversion in a compact footprint. It provides a nominal output of 58 Vdc at up to 3.88 A. Under natural convection cooling with 100-264 Vac input, it delivers 120 W of continuous output power. With 13 CFM forced air cooling, output power increases to 225 W. The converter achieves up to 94% efficiency, reducing thermal dissipation.
Input voltage range is 80-264 Vac at 47-63 Hz. It includes protections such as over voltage, over current, and hiccup short circuit protection with auto recovery. The unit offers line regulation of ±0.5% and load regulation of ±1%. Output ripple and noise is 580 mVp-p maximum.
Packaged in an open-frame chassis-mount format, the dimensions are 101.6 mm x 50.8 mm x 25.4 mm (4.00" x 2.00" x 1.00"). Operating temperature range is -40°C to 70°C with derating. Safety approvals include EN 60950-1, IEC 60950-1, and UL 6095. The converter complies with EN 55024, EN 55032 Class B, and EN 61000-3-2 / 3-3 emission standards.
