Yokogawa PW301 S4 Power Supply Module - Reliable Industrial DC Power Conversion
The Yokogawa PW301 S4 is an industrial-grade power supply module designed to deliver stable, regulated DC power for CENTUM VP distributed control systems and ProSafe-RS safety instrumented systems. Engineered for continuous operation in demanding process environments, this module ensures uninterrupted power delivery to critical control infrastructure with built-in protection mechanisms and diagnostic capabilities.
Core Technical Parameters
- Input Voltage: 100-120V AC, 50/60 Hz with wide tolerance range (±10%)
- Output Voltage: 5.1V DC regulated with ±2% accuracy under full load conditions
- Output Current: Maximum 10A continuous rating with 12A peak capability for transient loads
- Power Capacity: 51W nominal output for powering multiple I/O modules and communication interfaces
- Efficiency: >75% typical efficiency reduces heat generation and energy consumption
- Ripple & Noise: <50mV peak-to-peak ensures clean power for sensitive analog circuits
- Holdup Time: >20ms at full load maintains operation during brief power interruptions
- Protection Features: Overcurrent, overvoltage, short-circuit, and thermal shutdown safeguards
- MTBF: >200,000 hours calculated per MIL-HDBK-217F standards
- Operating Temperature: 0°C to +55°C ambient with derating above 45°C
Industrial Application Scenarios
The PW301 S4 serves as the primary power backbone for distributed control architectures in refineries, petrochemical complexes, pharmaceutical manufacturing facilities, and power generation plants. Its compact form factor enables dense cabinet configurations while maintaining thermal management efficiency. The module supports both standalone and redundant power configurations, making it ideal for high-availability applications where system downtime translates to significant production losses.
Redundancy & Reliability Solutions
When deployed in N+1 redundant configurations, multiple PW301 S4 modules automatically load-share through integrated ORing diodes, eliminating single points of failure. The hot-swap design permits field replacement during live operation without disrupting connected equipment—a critical capability for 24/7 process facilities. Front-panel LED indicators provide instant visual confirmation of operational status, AC input presence, and DC output health.
System Integration & Compatibility
The PW301 S4 mounts directly onto Yokogawa NFBU series base modules using standardized DIN rail or panel-mount brackets. Its universal input voltage range accommodates global power standards, simplifying spare parts inventory for multinational operations. The module interfaces seamlessly with Yokogawa's comprehensive I/O portfolio including analog input/output modules, digital I/O cards, Foundation Fieldbus interfaces, and HART communication modules.
Diagnostic & Maintenance Features
Advanced self-diagnostics continuously monitor internal temperatures, output voltage regulation, and load current draw. Fault conditions trigger both local LED annunciation and remote alarm signals to the host DCS, enabling predictive maintenance strategies. The module's conformal-coated PCB assembly resists moisture, dust, and corrosive atmospheres common in industrial settings, extending service life beyond standard commercial power supplies.
Installation & Configuration
Installation requires minimal wiring—AC input terminals accept 14-22 AWG conductors while DC output connects via high-reliability spring-clamp terminals. The module auto-detects input frequency and requires no manual voltage selection switches. Compliance with UL508, CSA C22.2, and CE directives ensures global regulatory acceptance for hazardous and non-hazardous area installations.
