- High Efficiency: 92% conversion efficiency reduces energy consumption and heat generation.
- Compact Design: Lightweight (0.34 kg) and space-saving for dense control cabinets.
- Rugged Reliability: ISA G3 compliance (corrosion resistance) and -20°C to 70°C operating range for harsh environments.
- Easy Integration: Plug-and-play design with Yokogawa’s DCS ecosystem, minimizing installation complexity.
Application Areas and Cases
- Industries: Petrochemical, power generation, water treatment, manufacturing.
- Case Example: A manufacturing plant integrated the SPW482-53 to power 20+ I/O modules in a distributed control system. The module’s dual outputs and voltage stability eliminated power-related downtime, improving production uptime by 15%.
Competitor Comparison
Compared to standard power supplies, the SPW482-53 offers a broader temperature range (-20°C to 70°C vs. -10°C to 55°C typical) and native DCS compatibility, reducing the need for adapters. Its dual-output configuration (5.1V + 24V) simplifies wiring versus single-output solutions, while ISA G3 compliance enhances corrosion resistance in industrial settings.

Selection Recommendations
- Voltage Requirements: Verify input voltage (AC) and output current (5.1V/24V) match system needs.
- Environment: Choose the -53 suffix (ISA G3, -20°C to 70°C) for corrosive or extreme-temperature sites.
- Scalability: Pair with Yokogawa’s field control units (e.g., FCN series) for modular system expansion.
- Budget: Balance efficiency (92%) and long-term savings against upfront costs.
Precautions
-
Installation: Use shielded cables for signal wiring; separate power and signal lines to prevent EMI.
-
Power Safety: Disconnect AC supply before module replacement; ensure grounding per NEC/CE standards.
-
Maintenance: Monitor output voltages quarterly; replace if efficiency drops below 85%.
-
Compatibility: Only use Yokogawa-approved accessories (e.g., cables, terminals) to avoid compatibility issues.
-
Redundancy: For critical systems, deploy dual modules with redundant power feeds.
