Delta DIN Pro and DIN Eco Series - New DIN Rail Industrial Power Supplies for 2026
Power Stability and Compact Design as a Dual Strategy
Control cabinet space is a finite resource. As industrial systems grow more complex, the pressure to fit more functionality into smaller enclosures increases – while simultaneously, the power demands of modern automation, AI infrastructure, and green energy installations are rising sharply.
Delta's two new DIN rail industrial power supply series for 2026 address both sides of this challenge simultaneously. The DIN Pro Series and DIN Eco Series are designed around a common set of priorities: minimal cabinet footprint, reliable operation under harsh environmental conditions, and the performance characteristics demanded by high-end industrial and infrastructure applications. Both series feature housing widths as narrow as 30 mm, maximising the number of components that can be installed within a standard control cabinet layout.
DIN Pro Series - High-Power Single-Phase Supply for Demanding Automation
The DIN Pro Series is a single-phase power supply covering an output power range from 120 W to 960 W, designed for applications where power stability and thermal resilience are critical requirements.
Key characteristics include:
- 150% power boost capability sustained for up to 5 seconds, providing the energy reserve needed to handle high inrush currents during motor startup without interrupting system operation
- Operating temperature up to 80 °C with full-load output maintained at 60 °C, supporting deployment in thermally demanding enclosures
- Cold start capability down to -40 °C for reliable initialisation in extreme ambient conditions
- 400 V DC input support for AI cooling distribution units (CDUs), green energy infrastructure, and energy storage system integration
- SEMI F47 compliance for semiconductor equipment voltage sag immunity, ensuring uninterrupted power on precision production lines
Target applications for the DIN Pro Series include AI thermal management CDUs, semiconductor manufacturing equipment, collaborative robots (cobots), and EV charging station infrastructure.
DIN Eco Series - Three-Phase Efficiency for Smart Factories and Green Energy
The DIN Eco Series is a three-phase power supply engineered for cost-effective, high-efficiency operation in modern industrial environments.
Key characteristics include:
- Up to 95% efficiency, significantly reducing energy losses in continuous-operation industrial installations
- Three-phase AC input range of 340-575 V AC as standard, with 3ENA models supporting input voltages up to 600 V AC for environments with frequent grid fluctuations or unstable supply conditions at remote sites
- Cold start capability down to -40 °C
- SEMI F47 compliance
- 30 mm housing width for space-efficient cabinet installation
The DIN Eco Series is aimed at smart factory automation systems and green energy facilities where three-phase supply infrastructure is available and operational efficiency is a primary design criterion.
Shared Features Across Both Series
Both the DIN Pro and DIN Eco series are built around a common set of environmental and reliability requirements that define their suitability for demanding industrial deployment:
- Housing widths from 30 mm for maximum space efficiency in control cabinets
- Cold start at -40 °C for operation in extreme temperature environments
- SEMI F47 standard compliance for semiconductor and precision manufacturing applications
- Designed for harsh industrial environments with high reliability as a baseline requirement
