The CUI Inc. VMS-275-58 is an AC-DC power supply designed for various applications, including medical. This open-frame unit provides a nominal 58V output and can deliver up to 160W of power under natural convection cooling, or 275W with forced air.
Key electrical specifications include a wide input voltage range of 80-264 Vac, a power factor of 0.95 at full load, and high efficiency up to 92%. The operating temperature range is -40°C to 70°C with derating. Protections include over-voltage, over-current, and short-circuit protection.
The VMS-275-58 features an industry-standard 3" x 5" footprint with a low profile of 0.75". It is designed for chassis mounting and includes features like adjustable output, power factor correction, and a standby output for a fan.
Compliance is met with standards such as IEC 60601-1-2:2014 (4th edition), FCC, UL, and TUV, making it suitable for demanding environments.
The VMS-275-58 provides a nominal 58V output with a maximum current of 4.74A.
The operating temperature range is -40°C to 70°C.
It accepts a universal input of 80 to 264 Vac at 47 to 63 Hz.
It includes over voltage protection (110-140%), over current protection (110%), and short circuit protection, all with hiccup mode and auto recovery.
The maximum efficiency is 92%.
The dimensions are 127.0 mm x 76.2 mm x 19.1 mm (5.00" x 3.00" x 0.75").
It holds medical safety approvals including EN 60601-1, UL, TUV, CB Scheme, and FCC Class B.
