YOKOGAWA SPW482-53

Advantages and Features

• Dual Output Stability: Delivers 5.1V and 24V DC power for control and field devices, ensuring consistent performance.
• Wide Input Range: Supports 220–240V AC with ±10% tolerance, suitable for fluctuating power grids.
• 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.
