Segmental Insights

Why Does AC to DC Converter Dominate the Global Industrial Power Supply Market?

The AC to DC converter segment is expected to account for 47.0% of the global industrial power supply market share in 2026. AC to DC converters dominate because industrial facilities commonly receive alternating-current utility power. Industrial equipment needs regulated direct current electricity from electronic components. Programmable logic controllers, sensors, actuators, and communication systems commonly operate using DC power. Industrial automation therefore creates consistent demand for AC to DC conversion. Modern converters also offer great efficiency, compact construction, voltage regulation and protective features. These features make for dependable operation in manufacturing equipment and industrial control systems.

On May 20, 2026, Delta announced the launch of their 2026 flagship DIN rail industrial power supply, the DIN Pro Series and the DIN Eco Series on May 20, 2026. The two series are available in widths down to 30 mm for optimal utilization of space in control cabinets. Reliable operation in rugged industrial environments and uninterrupted power for precise production lines are ensured by cold start capability down to -40°C and SEMI F47 certification for semiconductor equipment immunity.

Why is Up to 500 W the Most Preferred Output Power?

The up to 500 W segment is expected to account for 38.0% of the global industrial power supply market share in 2026. Power sources up to 500 W are preferred as many industrial control systems require modest power levels. They can be used to power programmable logic controllers, sensors, relays, communication modules, and control components. 24 V DC power is supplied to all control cabinets by most industrial equipment. The moderate power ratings also make for compact equipment designs and efficient use of cabinet space. Lower-capacity supplies tend to run cooler and take up less room for installation. These features make the section suited for several industrial automation applications. For example, Carlo Gavazzi has upgraded its SPDL DIN rail power supply series to include a 480 W version in 2025. SPDL480: 24 V DC output, 20 A current rating. It is 45 mm wide thus it saves a lot of room on the control panel. Its 45-millimeter width enables substantial control-panel space savings. Efficiency reaches 95%, while integrated protection covers overload, overvoltage, short circuits, and overtemperature.

Industrial Automation Dominates the Global Industrial Power Supply Market

The industrial automation segment is expected to account for 26.0% of the global industrial power supply market share in 2026. Industrial automation dominates because automated machinery requires stable and continuous electrical power. Reliable power supply are required for programmable logic controllers, sensors, actuators, motors and industrial networks. These automation components are coupled to industrial power sources which keep the DC voltage controlled. Increasingly, manufacturing facilities are turning to automated production systems to improve consistency and control in their operations. Protection of automation equipment against voltage fluctuations, overloads and short circuits is also required. Therefore, industrial power supplies remain vital components in automated production and process-control contexts. Phoenix Contact has launched the TRIO DC UPS for use in machine construction in April 2025. The small system combines a switched-mode power supply and an uninterruptible power supply. saves control cabinet space and increases power availability during interruptions.
