The CUI Inc. VSBU-120-T305A is an open frame AC-DC power supply designed for chassis mounting. It delivers up to 120W of continuous power with a universal input voltage range of 90-260 Vac.
This power supply features triple outputs: 5V, 24V, and -12V, with maximum output currents of 3.5A, 0.8A, and 0.8A respectively. It boasts an efficiency of 80% and includes active power factor correction (PFC).
Key electrical specifications include line regulation of 0.5% and load regulation of 5%. The operating temperature range is 0°C to 70°C with derating. Protections include input surge current, over voltage, over load, and over current.
With its industry-standard 3" x 5" footprint and robust features, the VSBU-120-T305A is suitable for various ITE (Commercial) applications.
The unit provides 5V at 3.5A, 24V at 0.8A, and -12V at 0.8A.
It operates on a universal input of 90 to 260 Vac at 47 to 63 Hz.
Continuous operation is rated from 0°C to 70°C with derating applied at higher temperatures.
It utilizes an open frame construction designed for direct chassis mounting.
The 24V output exhibits a maximum ripple and noise of 240 mVp-p.
The transient response recovers within 4 milliseconds when tested at 100 Vac.
It meets 55024, 55032 Class B, 60950-1, 61000-3-2, and 61000-3-3 standards.
