The CUI Inc. VOF-225A-24 is an open frame AC/DC converter from the VOF-225A series. It accepts a universal input of 80 to 264 Vac and delivers a single regulated 24 Vdc output at up to 5 A. The converter provides 120 W with natural convection cooling and up to 225 W with 13 CFM forced air.
Key electrical specifications include a typical efficiency of 93%, line regulation of ±0.5%, load regulation of ±1%, and a ripple and noise of 120 mVp-p. The unit features over voltage, over current, and short circuit protections with hiccup mode and auto recovery. A built-in trim pot allows output voltage adjustment of ±3%.
The converter measures 101.6 mm x 50.8 mm x 25.4 mm and is designed for chassis mount installation. It is suitable for ITE (commercial) applications and carries safety approvals to EN 60950-1, IEC 60950-1, and UL 6095.
The output voltage is 24 Vdc with a maximum output current of 5 A.
The operating temperature range is -40°C to 70°C with derating.
It includes over voltage protection (110-140%), over current protection (110% minimum), and short circuit protection, all with hiccup mode and auto recovery.
The typical efficiency is 93%.
The dimensions are 101.6 mm (length) x 50.8 mm (width) x 25.4 mm (height).
