Core Specifications and Ruggedized Design
The Cisco IR-PWR-G2A-AR= is a high-efficiency power supply module engineered for industrial IoT deployments requiring uninterrupted operation in extreme conditions. Designed to meet IP40-rated protection against dust and particulate ingress, this module operates reliably across -40°C to 70°C temperature ranges. Its 24–60 V DC input range accommodates unstable power grids commonly found in oil refineries, mining sites, and transportation systems.
Key hardware features include:
- Dual redundant power inputs: Ensures <5ms failover during power disruptions
- Fanless thermal design: Eliminates moving parts for reduced maintenance
- Galvanic isolation: 1.5kV isolation between input/output circuits for surge protection
Technical Innovations in Power Delivery
1. High-Density Efficiency
Leveraging GaNpowIR technology, this module achieves 94% peak efficiency – 10% higher than traditional silicon-based MOSFET solutions. The GaN-based architecture reduces switching losses, enabling compact designs for space-constrained industrial cabinets.
| Parameter | IR-PWR-G2A-AR= | Conventional Industrial PSU |
|---|---|---|
| Efficiency | 94% @ 50% load | 82-88% |
| Power Density | 35W/in³ | 18-25W/in³ |
| MTBF | 500,000 hours | 300,000 hours |
2. Advanced Protection Mechanisms
- Overvoltage/Undervoltage Lockout (OVP/UVP): Automatically disconnects loads during voltage anomalies
- Hot-swappable design: Supports replacement without system shutdown
- IEC 62443-4-2 compliance: Meets industrial cybersecurity standards for OT networks
Deployment Scenarios and Use Cases
Smart Grid Substations
In a 2024 U.S. utility upgrade, the IR-PWR-G2A-AR= powered phasor measurement units (PMUs) during winter storms. Its -40°C cold-start capability ensured continuous operation where competing modules failed.
Autonomous Mining Vehicles
A Chilean copper mine deployed this module to support LiDAR navigation systems on driverless haul trucks. The 50g vibration resistance (IEC 60068-2-6) prevented failures on rocky terrain.
Technical Considerations for Buyers
Q: Can it integrate with legacy 48V DC systems?
Yes, via auto-ranging DC input that accepts 24–60V without additional converters.
Q: How to ensure compatibility with Cisco Industrial Network Director?
The module supports Cisco Cyber Vision integration for real-time power analytics and threat detection.
