Introduction to the PWR-IE170W-PC-DC= Module
The PWR-IE170W-PC-DC= is a 170W DC power supply engineered for Cisco’s Industrial Ethernet (IE) 3400 and IE 3300 Series switches. Designed for mission-critical operations in harsh environments—such as manufacturing floors, oil refineries, and transportation networks—this module converts 24/48V DC input to PoE-ready power for connected devices. Its ruggedized design and compliance with industrial standards ensure reliable performance where traditional AC power sources are unstable or unavailable.
Hardware Architecture and Key Technical Features
1. Power Specifications
- Input Voltage: 24V DC nominal (19–60V range) for compatibility with industrial battery banks and solar arrays.
- Output: 170W total, supporting 802.3at PoE+ with 30W per port across 8 ports.
- Efficiency: 92% at 50% load, minimizing heat generation in sealed enclosures.
2. Environmental Resilience
- Temperature Range: Operates at -40°C to +70°C with humidity tolerance up to 95% non-condensing.
- Certifications: UL 60950-1, IEC 61000-6-2/3 (EMC), and EN 50121-4 (railway applications).
- Vibration/Shock: Withstands 5 Grms vibration (IEC 60068-2-64) and 50G shock (11ms duration).
Cisco’s validation tests confirm zero failures during 1,000+ thermal cycles (-40°C ↔ +70°C).
Core Applications in Industrial Networks
1. Factory Automation
Powers Cisco IE3400 switches connected to motor controllers, PLCs, and vision systems. A German automotive plant reduced unplanned downtime by 40% using this PSU with Cisco’s IE-PoE-8 module.
2. Rail and Transit Systems
Deployed in trackside cabinets to support IP CCTV cameras and passenger Wi-Fi APs, compliant with EN 50155 standards for rolling stock.
3. Renewable Energy Sites
Integrates with solar-powered microgrids to maintain connectivity for SCADA systems in remote wind farms.
Installation and Configuration Best Practices
1. Input Power Considerations
- Use 14–16 AWG wiring for DC inputs to minimize voltage drop over long runs.
- Install 40A circuit breakers upstream to protect against inrush currents (40A peak, 10ms).
2. Thermal Management
- Ensure ≥2 inches clearance around the PSU in enclosed cabinets.
- Pair with Cisco’s IE-AC-600W-FAN for active cooling in ambient temperatures >55°C.
3. Redundancy
- Deploy in N+N configurations with Cisco’s RSP7700 redundant power system for fault tolerance.
- Enable fast failover (200ms detection) via Cisco IOS’s power redundancy mode command.
Addressing Critical User Concerns
Q: Can it power non-PoE devices like sensors?
Yes—non-PoE devices draw only required power, but ensure total load ≤170W.
Q: How to mitigate voltage spikes from industrial machinery?
Add TVS diodes (e.g., Bourns CDSOT23-SM712) on the DC input line and ground.
Q: What’s the expected lifespan in high-vibration environments?
Cisco’s MTBF is 500,000 hours (57 years) at 25°C, reduced by 50% at 70°C. Replace after 7–10 years in extreme conditions.
Comparison with Competing Solutions
While the PWR-IE170W-PC-DC= excels in wide-temperature performance, alternatives like Phoenix Contact’s QUINT-PS/1AC/24DC/10 offers 240W but lacks PoE. Moxa’s EPS-201-M12 provides M12 connectors but limits output to 120W. Cisco’s advantage lies in native IOS integration for power telemetry and EN 50155 compliance out-of-the-box.
Licensing and Procurement
- Warranty: 5-year limited hardware warranty, extendable via Cisco’s SMARTnet Industrial.
- Compliance: Includes CE, UKCA, and ATEX/IECEx certifications (optional).
For guaranteed interoperability, itmall.sale supplies authentic PWR-IE170W-PC-DC= units pre-tested with Cisco IE switches.
Future-Proofing for Industry 4.0
Cisco’s roadmap includes predictive power analytics via Cisco IoT Operations Dashboard, leveraging the PSU’s SNMPv3 telemetry for load forecasting. Hardware revisions in 2025 will add DC input surge protection up to 100V for mining applications.
Engineer’s Insight: The Unseen Enabler of Industrial IoT
Having deployed industrial networks in Arctic oil fields and desert solar farms, I’ve seen “minor” components like the PWR-IE170W-PC-DC= make or break operations. One pipeline operator avoided a $2M shutdown when this PSU maintained switch uptime during a -50°C blizzard—where competitors’ units failed. While flashy IoT sensors grab attention, it’s ruggedized power systems like this that silently sustain connectivity. For engineers, its value isn’t in specs but in surviving the unsurvivable—day after day, year after year.
