Description

1. Product Description

The YOKOGAWA PW502 is a high-reliability power supply module designed for industrial automation systems, particularly Yokogawa’s CENTUM VP/VE/VN Distributed Control Systems (DCS). Engineered for stable and efficient power distribution, the PW502 delivers 24V DC output at 50A (1200W) with 90% efficiency, supporting continuous operation in harsh environments. Its compact design (240 mm x 140 mm x 70 mm) and IP66 protection rating ensure resistance to dust, moisture, and vibrations, making it suitable for manufacturing, energy, and chemical processing industries. The module accepts a wide input voltage range (100–240V AC) and features overload/short-circuit protection, minimizing downtime. As part of Yokogawa’s industrial control portfolio, the PW502 integrates seamlessly with DCS components, providing redundant power for critical systems.

6. Selection Recommendations

  • Voltage Requirements: Choose PW502 (220–240V AC) or PW501 (100–120V AC) based on local power standards.
  • Environment: Opt for IP66-rated models (PW502) for outdoor/ dusty/wet environments; use IP20 models for controlled indoor settings.
  • Power Needs: Match output current (50A) to system load; consider redundancy for critical applications.
  • Compatibility: Ensure integration with Yokogawa DCS (CENTUM VP/VE/VN) or third-party systems via standard interfaces.

7. Precautions

  • Installation: Mount vertically for optimal heat dissipation; ensure adequate ventilation (clearance ≥50 mm on all sides).
  • Wiring: Use shielded cables for signal lines; separate power and signal wiring to prevent interference.
  • Redundancy: Configure dual PW502 modules for fault tolerance (follow Yokogawa’s redundancy guidelines).
  • Maintenance: Schedule annual inspections for dust buildup; replace modules every 10 years (per Yokogawa’s lifecycle recommendations).
  • Safety: Disconnect power before servicing; follow local electrical codes for grounding.
