EMERSON SDN 20-24-100C 24VDC 20A Industrial DIN Rail Power Supply – Sola/Hevi-Duty SDN Series
When a DIN rail power supply fails on the production floor, the consequences are immediate and costly: PLCs lose power, control panels go dark, safety interlocks drop out, and entire lines halt within seconds. For facilities running 24/7 operations — automotive assembly, food processing, water treatment, or discrete manufacturing — an unplanned shutdown can cost thousands of dollars per minute. The EMERSON SDN 20-24-100C is engineered to eliminate that risk, delivering stable, regulated 24VDC power to your most critical control circuits with the reliability that industrial environments demand.
The SDN 20-24-100C sits at the high-current end of Emerson’s Sola/Hevi-Duty SDN Series — a globally recognized family of DIN rail power supplies trusted by OEMs and system integrators across more than 80 countries. With a 20A continuous output rating at 24VDC, this unit is purpose-built for demanding panel applications where load stability, wide input voltage tolerance, and compact footprint are non-negotiable. It is a direct replacement and upgrade path for legacy Sola and Hevi-Duty units, making it a preferred choice for MRO procurement teams worldwide.
