The VMS-80-18 is a high-efficiency AC DC converter from CUI Inc. designed to deliver 18V DC at 80W from a universal input of 90-260 Vac. With an efficiency rating of 85%, it minimizes power loss and heat generation. The converter features comprehensive protections including over voltage, over current, and short circuit protection with automatic recovery. It offers a ripple and noise of 180 mVp-p and maintains regulation within ±1% line and ±7% load. The device is isolated with 5,656 Vdc input-to-output isolation and 2,828 Vdc input-to-ground. It has a hold-up time of 16 ms at 110 Vac full load. The operating temperature range is 0°C to 70°C with derating above 50°C. The MTBF is 100,000 hours per MIL-HDBK-217F. This converter is suitable for a wide range of applications requiring a reliable and efficient 18V power supply.
