The CUI Inc. VOF-550C-48-CNF is an enclosed AC-DC power supply designed for industrial and commercial applications. It delivers a 48V output voltage with a maximum output power of 550W under airflow conditions, and 320W under natural convection.
This power supply operates with a wide input voltage range of 90-264 Vac and features active Power Factor Correction (PFC), achieving a typical efficiency of 94% at 230 Vac. Key electrical specifications include a maximum output current of 11.46A, a maximum ripple and noise of 200mVp-p at full load, and a hold-up time of 10ms at 115/230 Vac.
Designed for robust performance, it operates within a temperature range of -40°C to 70°C with derating. The unit has a 3" x 5" footprint and is suitable for chassis mounting. Additional features include standby output, power good signal, and remote sense capabilities.
Safety certifications include CE, cURus, and UKCA, with design compliance to 60335-1 and 62368-1 standards.
The converter accepts 90-264 Vac (47-63 Hz) and 127-370 Vdc.
48 Vdc output, rated at 550W maximum with airflow or 320W under natural convection.
