Overview
Delta's 2026 flagship DIN rail industrial power supplies split into two lines. The DIN Pro Series is the premium single-phase family, spanning 120 W to 960 W with a 150% power boost held for up to five seconds so downstream motor-start inrush does not collapse the rail. It also accepts a 400 VDC input, which lets the supply run from the DC bus of an AI cooling distribution unit or an energy-storage rack instead of an AC feed.
The DIN Eco Series is the three-phase counterpart, reaching up to 95% efficiency. Both families fit widths down to 30 mm, cold-start at -40C, operate to 80C ambient while holding full load at 60C, and carry SEMI F47 compliance for the voltage-sag immunity that semiconductor tools demand.
Key Benefits
30 mm width returns cabinet space on dense control panels. 150% boost for 5 seconds rides through motor and contactor inrush without oversizing the supply. 400 VDC input unifies AI CDU racks on a DC bus. SEMI F47 + conformal coating suit semiconductor fabs and polluted industrial floors.
Applications
AI data-centre cooling distribution units, semiconductor process equipment, collaborative-robot controllers, EV charging pedestals, control-cabinet power for machine tools and packaging lines, and energy-storage and green-energy infrastructure.
