PWR-IE50W-AC-L= Industrial AC Power Supply: Technical Specifications, Deployment Strategies, and Compatibility

Introduction to the PWR-IE50W-AC-L=

The ​​PWR-IE50W-AC-L=​​ is a compact, ruggedized AC-to-DC power supply engineered for Cisco Industrial Ethernet (IE) series devices operating in harsh environments. Designed to meet ​​IEC 61850-3​​ and ​​IEEE 1613​​ standards for power substations and transportation networks, this 50W PSU provides reliable 12V DC output even in extreme temperatures, high vibration, and electromagnetic interference (EMI)-heavy settings. Its plug-and-play integration with Cisco’s IE switches and routers simplifies deployments in oil and gas, manufacturing, and smart grid infrastructures.

Core Technical Specifications

Electrical Performance

• ​​Input Voltage​​: 90–264V AC (47–63 Hz), universal compatibility for global grids.
• ​​Output​​: 12V DC ±1%, 4.16A max (50W continuous).
• ​​Efficiency​​: 88% typical at 230V AC, compliant with ​​ErP Lot 7​​ and ​​CoC Tier 2​​ efficiency standards.
• ​​Protections​​: Over-voltage (13.5V cutoff), short-circuit, and over-temperature shutdown.

Mechanical and Environmental Resilience

• ​​Housing​​: Die-cast aluminum with IP40 rating, corrosion-resistant finish.
• ​​Operating Conditions​​:
  • ​​Temperature​​: -40°C to +70°C (full load up to +60°C).
  • ​​Humidity​​: 5–95% non-condensing.
  • ​​Vibration​​: 5G @ 10–500 Hz (compliant with ​​IEC 60068-2-64​​).
• ​​Mounting​​: DIN rail (TS35/7.5/15) or direct panel mounting via M4 screws.

Compatibility with Cisco Industrial Devices

The PWR-IE50W-AC-L= is validated for use with:

• ​​Cisco IE3300/IE3400 Industrial Switches​​: Powers PoE (802.3at) ports for connected sensors and cameras.
• ​​Cisco IR1101 Integrated Services Router​​: Supports dual PSU configurations for redundancy.
• ​​Cisco IC3000 Industrial Compute Gateway​​: Delivers stable voltage for edge computing workloads.

​​Critical Note​​: Incompatible with non-industrial Cisco Catalyst 9000 or Meraki MS series due to differing connector types (4-pin terminal block vs. 3-pin IEC).

Deployment Best Practices for Critical Infrastructure

Step 1: Power Redundancy Configuration

• For mission-critical sites, deploy two PWR-IE50W-AC-L= units in ​​active/standby mode​​ using Cisco’s ​​Power Redundancy Protocol (PRP)​​.
• Ensure AC inputs are sourced from separate circuits to mitigate grid failures.

Step 2: Environmental Hardening

• Mount the PSU vertically to optimize heat dissipation in enclosed cabinets.
• In high-EMI environments (e.g., near variable frequency drives), use shielded conduit for AC input wiring.

Step 3: Integration with Cisco Management Tools

• Use ​​Cisco DNA Center​​ to monitor PSU health metrics (load %, input voltage).
• Configure ​​Cisco Cyber Vision​​ to correlate power anomalies with network security events.

Addressing Key User Concerns

​​Q: Can this PSU handle voltage sags in regions with unstable power grids?​​
A: Yes. The wide input range (90–264V AC) compensates for sags down to 90V for up to 500ms. For prolonged outages, pair with a UPS.

​​Q: Is the PSU suitable for outdoor installations without enclosures?​​
A: No. Despite its IP40 rating, prolonged exposure to rain or dust requires an additional ​​NEMA 4X-rated enclosure​​.

​​Q: How does it perform in high-altitude environments (>2000m)?​​
A: Derating is required above 2000m—reduce max load to 40W at 3000m due to reduced air density affecting cooling.

​​Q: What is the expected service life under continuous operation?​​
A: 150,000 hours MTBF at +40°C ambient, per ​​Telcordia SR-332​​ testing.

Procurement and Firmware Compliance

To ensure compatibility and warranty coverage, source the PWR-IE50W-AC-L= exclusively through authorized channels like [“PWR-IE50W-AC-L=” link to (https://itmall.sale/product-category/cisco/). Third-party units often lack firmware signatures required for Cisco’s ​​Trustworthy System​​ validations, triggering alarms in DNA Center.

Operational Insights

The PWR-IE50W-AC-L= exemplifies Cisco’s industrial design ethos: uncompromising durability over modularity. While its fixed 12V output limits flexibility compared to multi-voltage PSUs, the hardened construction reduces failure points in environments where maintenance is costly or hazardous. A notable omission is the lack of hot-swappable connectors—a drawback for uptime-sensitive sites. Future iterations should prioritize tool-less replacement mechanisms, but for now, this PSU remains a robust choice for enterprises prioritizing reliability in extreme OT environments.
