The VMS-450B-12 is a 450W AC/DC converter from CUI Inc. designed for industrial and commercial applications. It accepts a wide input voltage range of 90-264 Vac at 47-63 Hz and provides a regulated 12V output at up to 37.5A. Typical efficiency is 90%, with ripple and noise limited to 240 mVp-p.
The converter includes comprehensive protection features: over voltage protection shuts down at 150% of nominal output, over current protection automatically recovers at 130%, and short circuit protection with auto recovery. It also provides a 12V fan drive output rated at 600 mA and a 5V auxiliary output at 1A.
This unit is suitable for systems requiring high power density and reliable performance. Its compact design and built-in protections make it ideal for powering equipment in telecom, networking, industrial control, and LED lighting applications.
