Equivalent & Substitute Parts for LDE20-20B12

Part Overview

The LDE20-20B12 from Mornsun America, LLC is an enclosed AC DC converter with a single 12V output rated at 1.66A (20 W total power). The device features a universal AC/DC input range of 85~264 VAC or 100~370 VDC, targeted at ITE (Commercial) applications. With its obsolete status, there is a necessity to identify strictly parametric equivalents for continued production, direct replacement needs, or BOM maintenance.
