VMS-160-12

The VMS-160-12 is a robust AC/DC converter manufactured by CUI Inc., designed for reliable power conversion in demanding environments. It provides a stable 12V DC output at up to 13.3A, delivering 100W under natural convection and scaling to 160W with forced air cooling. The unit operates efficiently at 90% typical efficiency while maintaining tight line and load regulation of ±1%. This converter accepts a wide universal input voltage range of 90-264V AC or 125-373V DC across 47-63Hz frequencies. It incorporates active power factor correction achieving a 0.98 power factor, reducing harmonic distortion on the input line. Electrical safety is ensured through a high isolation voltage of 5,656V DC between primary and secondary circuits, along with low leakage current of 275µA maximum. Built-in protections include over-voltage clamping at 130%, over-current limiting at 150%, and short-circuit protection with automatic recovery. The operating temperature range spans from -25°C to 70°C with derating applied above nominal thresholds. An integrated 12V DC fan drive output supports auxiliary cooling systems when required. Engineered for off-board power supply applications, this unit fits seamlessly into industrial control panels, telecommunications equipment, and medical devices requiring certified isolated power conversion. Its compact form factor and comprehensive electrical specifications make it suitable for space-constrained designs needing dependable performance.
