Delta’s New 3-Phase DIN Rail Power Supplies DIN Eco Series Empower Diverse Industrial Applications

As industrial systems expand and high uptime becomes more critical, Delta has launched the new DIN Eco Series 3-Phase DIN rail power supplies. With high conversion efficiency of up to 95.5%, the Series minimizes energy loss, heat buildup, and operating carbon emissions, perfectly aligning with the goal of sustainability. This DIN Eco Series offers 120 W, 240 W, 480 W, and 960 W models with 24 V and 48 V output options, engineered for diverse applications, including industrial control panels, data center cooling distribution units (CDU), green energy systems, and electric vehicle (EV) charging stations.

Moreover, the Series supports 3-phase AC grid connections from 340–575 Vac without requiring a neutral line. Its compact, high-power-density design maximizes space utilization within distribution panels, facilitating easy system expansion without the need for enclosure modifications. Additionally, with a wide operating temperature range of –40°C to 70°C, the DIN Eco Series ensures stable performance in even the most extreme industrial environments.

Designed for maximum safety, the DIN Eco 3-Phase Series delivers long-term reliability and uncompromising protection for both operators and critical equipment. It is certified to the most stringent international standards, including IEC/EN/UL 62368-1, 61010-1/-2-201, and GB 4943.1, providing comprehensive defense against electrical, thermal, and mechanical hazards. Beyond safety, the Series is SEMI F47 compliant, empowering systems to ride through brief power fluctuations and maintain uninterrupted operation in demanding semiconductor manufacturing environments.
