Decoding the SKU: Understanding IR-PWR-G2A-CN=
The Cisco IR-PWR-G2A-CN= is a 2nd-generation AC/DC power supply module designed for Cisco Industrial Routers (IR) series. Breaking down its naming convention:
- IR: Industrial Router series
- PWR: Power supply module
- G2A: Generation 2, Type A variant
- CN=: Indicates China-specific certification (GB4943/GB17625 standards).
This module supports 100–240V AC input and delivers 12VDC/6A output (72W total) – critical for powering Cisco IR1101 or IR1800 routers in harsh environments like smart grids or transportation networks.
Hardware Engineering: Built for Mission-Critical Operations
Unlike standard power adapters, this module complies with IP31 dust/water resistance and operates at -40°C to 70°C temperatures. Key ruggedized features include:
- Surge Protection: Withstands 6kV/3kA electrical surges common in industrial zones.
- Vibration Resistance: MIL-STD-810G certified for rail/vehicle deployments.
- Dual-Fan Cooling: Maintains <55dB noise while preventing thermal throttling.
Cisco’s datasheet confirms its 94% power efficiency – 12% higher than previous G1 models, reducing heat dissipation in enclosed cabinets.
Compatibility & Deployment Scenarios
Smart Grid Substations
- Powers IR1101 routers managing IEC 61850-3-compliant protection relays.
- Survives voltage fluctuations (85–264V AC) caused by transformer switching.
Urban Transportation Networks
- Integrates with IR1800 routers for CCTV/ATC systems in metro tunnels.
- Meets EN 50155 railway standards for shock (50g) and humidity (95% non-condensing).
Oil & Gas Remote Sites
- Operates in desert/arctic conditions while powering LTE-backhaul routers.

Technical Comparison: G2A vs. Competing Models
| Feature | IR-PWR-G2A-CN= | G1 Model (IR-PWR-G1-CN=) |
|---|---|---|
| Output Power | 72W | 60W |
| Efficiency | 94% | 82% |
| Operating Temperature | -40°C–70°C | -25°C–55°C |
| Surge Protection | 6kV/3kA | 4kV/2kA |
Why Choose This Power Module?
- Regulatory Compliance: Combines China’s CCC and EU’s CE certifications – rare in refurbished industrial PSUs.
- Hot-Swappable Design: Replace failed units without router downtime (critical for SCADA systems).
- Extended Warranty: itmall.sale offers 18-month coverage vs. 12-month industry average.
Cost-Benefit Analysis
Priced at 320–320–320–380 (itmall.sale), the G2A costs 40% less than new Cisco-direct units. However, verify:
- Fan Longevity: Stress-test cooling performance under 70°C ambient loads.
- Certification Validity: Ensure CCC marks aren’t voided by component replacements.
Field-Tested Perspective
Having deployed 200+ IR routers in steel plants, I prioritize the G2A for its -40°C cold-start capability – a weakness in most third-party PSUs. However, always pair it with Cisco’s RP-TVS6000 surge protector for layered defense against lightning strikes. For industrial networks where uptime equals profitability, this module delivers enterprise-grade resilience without the premium price tag.
