The CUI Inc. VMS-350-58 is an open-frame AC/DC power supply designed for chassis mounting. It provides a single output of 58V with a maximum current of 3.02A, delivering up to 175W of continuous power, or 350W with forced air cooling.
This power supply operates with a universal input voltage range of 90-264 Vac and features power factor correction (PFC), contributing to its high efficiency of up to 94%. It includes features such as adjustable output, a standby output, and protection against over-voltage, over-current, and over-temperature conditions.
The unit has a compact footprint with dimensions of 5.00" x 3.00" x 1.00" (127.0mm x 76.2mm x 25.4mm) and an operating temperature range of -40°C to 70°C with derating. It is suitable for applications requiring reliable power conversion, including medical equipment, due to its compliance with various safety and EMC standards like CB Scheme, FCC, and IEC.
Key electrical specifications include a line regulation of ±0.5%, load regulation of ±0.5%, and a switching frequency between 50-300 kHz. The VMS-350-58 also includes a 12V/0.5A fan output.
The input voltage range is 90 to 264 Vac.
The unit measures 127.0 mm x 76.2 mm x 25.4 mm (5.00 x 3.00 x 1.00 inches) and uses an open frame, chassis mount design.
The operating temperature range is -40°C to 70°C with derating.
It provides 58 Vdc at a maximum output current of 3.02 A.
Efficiency is up to 94%.
The converter is approved under CB Scheme, EN, FCC, IEC, TUV, and UL standards for medical applications.
