From PLCs and I/O modules to sensors, communications, and safety equipment, stable DC power ensures systems operate continuously and predictably. The Weidmüller PROeco II power supply range, available through Pacific Automation, has been designed to meet these requirements with high efficiency, compact design, and intelligent diagnostics.
PROeco II power supplies are suited to modern industrial environments where space, reliability, and energy efficiency are critical.
Industrial DC Power Designed for Critical Automation Systems
The PROeco II series covers a wide range of applications, with power ratings from 72 W to 960 W and 24 V and 48 V DC output options. This flexibility allows the range to support everything from small control systems through to more demanding automation installations.
Designed for continuous operation, these power supplies deliver stable output even under fluctuating load conditions, making them well suited to critical control and automation tasks.
Built for Reliable Operation in Industrial Environments
Industrial systems often operate in harsh and electrically noisy environments. PROeco II power supplies incorporate comprehensive protection features, including overload, short-circuit, and overvoltage protection, helping to protect connected equipment and reduce the risk of unexpected downtime.
These features contribute to long-term system reliability and provide confidence in applications where uninterrupted operation is essential.
High-Efficiency Power Supplies for Control Panels
Energy efficiency plays an increasingly important role in control panel design. PROeco II power supplies achieve efficiencies of up to 95 %, significantly reducing energy losses during power conversion.
Higher efficiency translates to lower heat generation inside enclosures, helping to improve overall system reliability, extend component life, and potentially reduce the need for additional cooling. This can deliver both operational and long-term cost benefits.
Diagnostics and Monitoring for Industrial Power Systems
To simplify commissioning and ongoing maintenance, PROeco II power supplies feature a three-colour LED status indicator. This allows technicians to quickly identify operating status, warning conditions, or faults directly at the device.
In addition, floating relay contacts provide the ability to integrate power supply status into higher-level monitoring or control systems. This enables faster fault detection and supports proactive maintenance strategies in complex automation environments.
Compact DC Power Supplies for Space-Constrained Panels
Control panel space is often limited, particularly in retrofit projects or compact machine designs. PROeco II units are approximately 15 % more compact than the previous generation, allowing more efficient use of DIN rail space.
For applications requiring higher capacity or increased availability, up to three power supplies can be connected in parallel. The range also integrates seamlessly with Weidmüller power management components such as DC UPS modules and diode modules, supporting scalable and redundant power architectures.
Supporting Efficient Engineering and System Design
PROeco II power supplies are designed to support modern engineering workflows. Digital planning data and compatibility with Weidmüller configuration tools allow engineers to design, document, and validate power systems during the project planning phase.
This helps reduce design effort, minimise errors, and streamline commissioning during installation.
A Reliable Power Supply Solution for Industrial Automation
For OEMs, system integrators, and industrial operators, the PROeco II range delivers a practical and reliable solution for powering automation systems:
- Stable DC power for industrial control equipment
- High efficiency to reduce energy loss and cabinet heat
- Integrated diagnostics for faster troubleshooting
- Compact design for efficient panel layouts
- Scalable configurations supporting redundancy and expansion
Whether designing a new automation system or upgrading existing infrastructure, PROeco II power supplies provide a dependable foundation for modern industrial control applications.
