VE-2ND-EX Equivalent & Substitute Parts Reference
Part Overview
The VE-2ND-EX from Vicor Corporation is an isolated DC-DC converter module in the VE-200™ (75W) series, delivering 85V output at up to 882mA from a 36V–76V input range. Key features include full brick package, 3kV isolation, and protections such as OCP, OTP, OVP, and SCP. The part is ROHS3 compliant and intended for ITE (Commercial) applications. As the VE-2ND-EX is classified as obsolete, identification of suitable equivalent or substitute models is essential for ongoing designs, maintenance, or replacement in existing systems.
