The CUI Inc. VF-D320-D1224A is an open-frame AC-DC power supply designed for ITE (Commercial) applications. It provides dual outputs of 12V and 24V, delivering a total of 320W of power. This unit features a universal input voltage range of 90-132/180-264 Vac and operates with an efficiency of up to 75%.
Key electrical specifications include line and load regulation of ±5%, a hold-up time of 20ms at 120 VAC, and a transient response that returns output voltage within 1% in under 2.5ms for a 50% load change. Protections include over-voltage, over-current (foldback mode), short circuit, and over-temperature auto-recovery.
Mechanically, the power supply is chassis mounted with dimensions of 152.4mm x 101.6mm x 38.1mm. It operates within a temperature range of 0°C to 70°C with derating. The VF-D320-D1224A also includes features such as a power good signal and a fan drive output for external cooling.
Safety and compliance certifications include UL, TUV, EN, IEC, and CB Scheme, supporting its use in various commercial and industrial systems.
