Vicor VE-274-MY Equivalent & Substitute Parts Reference
Part Overview
The Vicor VE-274-MY is a DC-DC converter module designed for isolated power applications requiring a single 48V output at 1.04A. Housed in a full brick package, it operates with a wide input voltage range of 100V to 375V and provides up to 50W of power. As a member of the VE-200™ (50W) series, the VE-274-MY offers 3kV isolation, ITE (Commercial) compliance, and multiple protective features including OCP, OTP, OVP, and SCP. This model is listed as obsolete, creating a need for alternative parts with matching electrical, mechanical, and compliance specifications.
