Delta DIN Eco Series 3-Phase DIN Rail Power Supplies
Efficient 3-Phase Power for Expanding Industrial Systems
As industrial systems become more complex, power supplies must do more than simply convert voltage. They must support high system availability, efficient panel integration, broad environmental tolerance, and stable operation under demanding grid conditions.
With the new DIN Eco Series 3-Phase DIN Rail power supplies, Delta addresses exactly these requirements. The series combines high conversion efficiency, compact mechanical design, and robust industrial certification in a product platform developed for modern industrial infrastructure.
Available through FORTEC Switzerland, the DIN Eco Series offers a scalable 3-phase DIN rail solution for applications where space, efficiency, and uptime are equally important.
Designed for Modern Industrial Infrastructure
The DIN Eco Series has been developed for industrial systems that require reliable DC power from 3-phase AC grid connections while maintaining compact panel design.
A key advantage of the series is its support for 3-phase AC input from 340 to 575 Vac, and it can also operate from 2-phase input within the same voltage range, depending on system architecture. The design does not require a neutral line, which simplifies integration in many industrial installations.
These characteristics make the series especially suitable for power architectures where flexibility and simplified wiring are essential.
High Efficiency for Lower Losses and Better Sustainability
Energy efficiency is one of the central strengths of the DIN Eco Series. With conversion efficiency of up to 95.5%, the power supplies reduce energy loss during operation and help minimize heat generation inside the control panel.
This provides several practical advantages:
- reduced thermal load inside the cabinet
- lower cooling requirements
- improved overall system efficiency
- reduced operating carbon emissions
For applications that run continuously or at high load, this efficiency improvement contributes directly to lower operating costs and more sustainable system design.
Broad Output Range for Diverse Applications
The DIN Eco Series is designed as a scalable platform and is available in 120 W, 240 W, 480 W, and 960 W versions, with 24 V and 48 V output options.
This makes the series suitable for a broad range of applications, including:
- industrial control panels
- data center cooling distribution units (CDUs)
- green energy systems
- EV charging stations
- other industrial systems with centralized DIN rail power architectures
The broad output range allows designers to align power level, panel space, and system demand within a consistent product family.
Compact Design for Efficient Use of Panel Space
In industrial control cabinets and distribution panels, available space is often one of the most limiting design factors.
The DIN Eco Series addresses this with a slim and compact high-power-density design, helping maximize usable space inside the enclosure. This is especially valuable in systems that need to be expanded later, because it allows additional functionality to be integrated without forcing enclosure redesign.
For machine builders and panel designers, this means more flexibility for future scaling with less mechanical redesign effort.
Stable Operation Across a Wide Temperature Range
Industrial installations are rarely exposed to ideal environmental conditions. Power supplies must therefore remain stable not only electrically, but also thermally.
The DIN Eco Series supports a wide operating temperature range from -40 °C to +70 °C, allowing reliable use in both low-temperature and high-temperature industrial environments.
This broad temperature capability makes the series suitable for systems installed in outdoor cabinets, industrial halls, energy infrastructure, and other demanding operating conditions.
Safety, Reliability, and Industrial Compliance
Delta has designed the DIN Eco Series with a strong focus on operator safety, equipment protection, and long-term reliability.
The series is certified to major international standards, including:
- IEC / EN / UL 62368-1
- IEC / EN / UL 61010-1
- IEC / EN / UL 61010-2-201
- GB 4943.1
These certifications support protection against electrical, thermal, and mechanical hazards in industrial environments.
In addition, the DIN Eco Series is SEMI F47 compliant, which is particularly relevant in semiconductor manufacturing and other sensitive industrial processes. This allows systems to ride through short power fluctuations without unnecessary interruption.
Additional Features for Industrial Integration
Beyond basic power conversion, the DIN Eco Series includes several features that support practical integration in industrial systems.
Depending on model, these include:
- built-in LED status indicator
- DC OK relay on models above 480 W
- surge protection capacity of 4 kV/2 kV
- optional 3ENA variants supporting 600 Vac and conformal coating
These features support system diagnostics, increase grid robustness, and extend applicability into harsher installation environments.
