The CUI Inc. VOF-275-58-1 is an AC/DC converter delivering a regulated 58 Vdc output at up to 4.74 A. The maximum output power is 160 W under natural convection and 275 W with forced air cooling. It achieves a typical efficiency of 92%. The converter accepts a universal input voltage range of 80-264 Vac at 47-63 Hz. Input current is 2.6 A at 115 Vac and 1.3 A at 230 Vac full load. Power factor correction provides a typical power factor of 0.95. The output is tightly regulated with ±1% set point accuracy, ±0.5% line regulation, and ±1% load regulation. The converter features a low no-load power consumption of 0.5 W. Operating temperature range is -40°C to 70°C with derating. Inrush current is 45 A at 230 Vac cold start. Leakage current is 0.3 mA at 230 Vac. This AC/DC converter is suitable for a variety of power supply applications requiring a 58 V output.
