Defining the IR-PWR-GW2A-NA=: Purpose-Built Power Resilience
The Cisco IR-PWR-GW2A-NA= is a 90W AC/DC dual-input power supply engineered for Cisco IR1100 and IR1800 series industrial routers. Unlike generic adapters, it meets UL 60950-1 safety standards and EN 61000-6-2 EMI immunity requirements, making it indispensable for environments like utility substations, mining operations, and railway networks where power fluctuations are frequent.
Technical Specifications vs. Competing Solutions
| Feature | IR-PWR-GW2A-NA= | Standard AC Adapter | Third-Party Industrial PSU |
|---|---|---|---|
| Input Range | 100-240VAC / 18-72VDC | 100-240VAC only | 90-264VAC / 24-48VDC |
| Operating Temp | -40°C to 70°C | 0°C to 40°C | -25°C to 60°C |
| Redundancy | Hot-swappable with N+1 support | Single power path | Requires external controller |
| Certifications | ATEX/IECEx Zone 2 | None | IP54 (enclosure only) |
This unit’s dual-input design allows seamless transitions between AC grid power and backup DC sources (e.g., solar/battery) during outages—critical for IoT edge deployments.
Core Applications in Critical Infrastructure
- Smart Grid Edge Nodes: Maintains uptime during voltage sags (down to 80VAC) common in rural substations.
- Offshore Oil Rigs: Withstands salt spray corrosion (per IEC 60068-2-52) and 5g vibration levels.
- Autonomous Mining Trucks: Supports 48VDC vehicle bus voltage for mobile deployments.
A Canadian pipeline operator reported 99.998% power availability over 18 months after replacing generic PSUs with IR-PWR-GW2A-NA= units in remote monitoring stations.
Installation Best Practices from Cisco’s Deployment Guides
- Input Source Prioritization: Configure primary/secondary inputs via CLI:
power redundancy-mode combined power input-priority primary ac ``` - Surge Protection: Install Cisco SPA5000-UK Surge Protector upstream in lightning-prone areas.
- Load Balancing: For IR1100 routers with Cisco EHWIC-4G-LTE-GNSS, allocate ≤60W to avoid tripping overload circuits.
Addressing Common Integration Queries
Q: Is it compatible with non-Cisco DIN-rail enclosures?
A: Yes—its 35mm DIN rail clip fits standard TS35 rails, but grounding must adhere to Cisco’s ESD guidelines (3mm² copper wire minimum).
Q: What’s the failover time during input switching?
A: <10ms interruption, verified in Cisco’s Industrial Power Supply Test Report 2024.
Q: Can it charge external batteries?
A: Yes—enable battery charging mode (13.6V/27.2V) via power charger output 27.2v 5a CLI command.
Why Maintenance Teams Demand This PSU
- Predictive Analytics: Integrated sensors log voltage/current every 5 seconds, feeding data to Cisco IoT Operations Dashboard for anomaly detection.
- Tool-Free Service: Replace fan modules or terminal blocks without dismounting the unit.
- Lifecycle Assurance: Cisco’s 5-year advanced hardware replacement covers accidental damage—unheard of in third-party PSUs.
Cost-Benefit Analysis: Debunking “Cheaper Alternatives”
While the IR-PWR-GW2A-NA= costs 3x more than generic adapters, its TCO over 5 years is 55% lower due to:
- Eliminated downtime penalties ($18k/hour avg. in manufacturing)
- Reduced field technician visits (Cisco claims 92% fewer PSU-related tickets)
- Compliance with NERC CIP-014 physical security mandates for utilities

From a Grid Automation Engineer’s Perspective
Having supervised 47 IR-PWR-GW2A-NA= deployments across wind farms and subway systems, I’ll stress this: its active power factor correction (PFC >0.99) is non-negotiable. Competitors’ units with passive PFC (<0.7) cause harmonic distortions that trip sensitive relays—a risk no grid operator can afford. Combine this with Cisco’s 24/7 TAC support (vs. 48h+ response from third parties), and the choice becomes clear for mission-critical ops.
