The CUI Inc. VSBU-120-T3125B is an open-frame AC-DC power supply designed for various applications. It delivers up to 120W of continuous power with a universal input range of 90-260 Vac.
This model features triple outputs with specific voltages of 3.3V, 12V, and 5V, each capable of delivering up to 6A, 0.8A, and 0.8A respectively. The power supply boasts an efficiency of 80% and includes active power factor correction (PFC).
Designed for easy integration, it has an industry-standard 3" x 5" footprint and chassis mount type. The unit operates within a temperature range of 0°C to 70°C with derating and includes protections against input surge current, over voltage, overload, and over current.
Key features include an internal EMI filter and no minimum load requirement, making it suitable for ITE (Commercial) applications. It is compliant with various standards including 55024, 55032 Class B, 60950-1, 61000-3-2, and 61000-3-3.
The converter accepts 90 to 260 Vac input and provides 3.3 Vdc, 12 Vdc, and 5 Vdc outputs.
The unit uses an open frame construction designed for chassis mounting.
The device operates continuously from 0 to 70 degrees Celsius with derating at higher temperatures.
The converter achieves 80 percent typical efficiency at full load.
Ripple and noise measure 66 mVp-p on the 3.3 V output and 120 mVp-p on the 12 V and 5 V outputs.
The chassis measures 127.0 mm in length, 76.2 mm in width, and 32.5 mm in height.
