III. Core Functions

1. Multi-channel Isolated Voltage Stabilized Output, System-level Power Assurance

As the core power supply unit of the control station, it can simultaneously output multiple isolated DC voltages, covering all the power supply requirements of system logic, analog I/O, and digital I/O. The output has high precision and low ripple, avoiding the impact of voltage fluctuations on the stability of control signals. It supports dual power redundancy parallel connection (2N redundancy), and two power units of the same model can operate synchronously with equal current distribution. In case of any power failure, it can achieve seamless switching without power interruption, ensuring the continuous operation of the DCS system.

2. Wide-range Adaptive AC Input, Global Grid Adaptability

Supports a wide range of AC input from 120–240VAC, with frequency adaptable to 47–63Hz. It can automatically identify 110V/120V or 220V/240V power grids without manual switching, adapting to industrial power supply standards of various countries around the world. The input side integrates EMI filter circuits, effectively suppressing grid surges, spike pulses, and electromagnetic interference, enhancing the system's anti-interference ability in complex electromagnetic environments.

3. Complete Protection Mechanism, Fault Automatic Protection

Built-in multiple industrial-grade protection functions, including overvoltage protection, overcurrent protection, short-circuit protection, and over-temperature protection. When output overload, short circuit, or environmental temperature exceeds the limit, the power supply can automatically limit output power or cut off power supply. After the fault is resolved, it can automatically recover, avoiding damage to the power supply and the subsequent controller, I/O card, and preventing the spread of faults, reducing the risk of failure escalation.

4. Hot Swap Design, Maintenance Without Shutdown

Supports online hot swap function. In the normal operation of the system, it can directly plug in and replace the faulty power supply without shutting down the control station or interrupting the production process, significantly simplifying the maintenance process and shortening the fault handling time, suitable for 24-hour continuous production conditions.

5. Real-time Status Monitoring, Operation Visualization

The power panel is equipped with LED status indicator lights, which can directly display the power operation status, including normal power, fault alarm, overload indication, etc. Maintenance personnel can quickly identify the power working status and promptly detect potential faults, reducing the difficulty of maintenance.

6. Industrial-grade Robust Design, Adaptability to Harsh Conditions

Uses high-strength aluminum alloy and steel shells, with surface treated for anti-static and anti-corrosion coating, possessing anti-vibration and anti-shock capabilities, capable of adapting to high-temperature, high-dust, and strong electromagnetic interference harsh industrial environments. Without fan natural convection cooling design, it reduces the risk of fan aging faults and improves long-term operational stability. 2. Output Parameters

VII. Compatibility and Replacement Relationship

1. Compatible Enclosures

Single-rack enclosure: 1D54580G01 (configures 1 1D54582G01 power supply)

Dual-rack enclosure: 1D54580G02 (configures 2 1D54582G01 power supplies, redundant configuration)

2. Alternative Models

Downward Compatibility: Can directly replace 1D54581G03, 1D54581G04 power supplies without modifying wiring, compatible with original enclosures and systems

Series Comparison: 1D54574G01/G02 are 1D series low-power power supplies (approximately 120W), suitable for low-end enclosures; 1D54582G01 is a high-power version, suitable for enclosures with 32 I/O cards fully loaded, with stronger load capacity.

VIII. Typical Application Scenarios

1. Thermal Power Generation

Used for redundant control stations of core equipment such as boilers, steam turbines, and generators to ensure stable operation of key control functions such as unit start-stop, load regulation, and safety interlock, suitable for long-term and high-reliability requirements in the thermal power industry.

2. Petrochemical Industry

Applied to DCS control cabinets of large-scale refining and chemical plants, reaction vessels, compression units, distillation towers, etc., suitable for high-temperature, corrosive, and flammable/explosive environments, ensuring uninterrupted operation of the control system during 24-hour continuous production.

3. Metallurgy / Cement

Compatible with core control stations of equipment such as blast furnaces, rolling lines, kilns, mills, etc., adapted to high-temperature, high-dust, and strong-vibration environments, ensuring precise control of temperature, pressure, and flow parameters during production.

4. Other Industrial Fields

Widely used in water treatment, natural gas, papermaking, etc. industries' key automation control systems, providing stable redundant power supply for DCS, PLC control stations, reducing the risk of production shutdown caused by power failure.

IX. Maintenance and Selection Suggestions

1. Spare Parts Selection

For maintenance of old systems, 1D54582G01 is preferred, as it has greater power and stronger stability, suitable for full-load enclosure load requirements; when budget is limited, original refurbished parts can be selected, with particular attention to checking output precision, load capacity, and protection functions.

2. Daily Maintenance

Regularly check the status of the power LED indicator lights, check if the connection terminals are loose and if the enclosure is dusty; conduct a load test once every 6 months to verify if the output voltage and current are normal, ensuring reliable redundant switching function.

3. Upgrade Suggestions

For new projects or system upgrades, consider the new redundant power supply solution of Ovation 4.0 platform, with better performance and maintainability; when expanding the old system, prioritize matching the same model 1D54582G01 power supply to ensure redundant compatibility.
