PWR-IE50W-AC Description

Cisco PWR-IE50W-AC is a compact 50W industrial DIN-rail power supply that converts AC mains into regulated 24V DC output for powering Cisco Industrial Ethernet switches, routers, and IoT gateways. Also referred to as the Cisco 50W AC industrial PSU, it delivers 2.1A at 24VDC, ensuring reliable power for edge networking devices in harsh environments. With universal AC 90–264V input and typical 80% efficiency, the unit provides stable operation across wide temperature ranges (-40°C to +75°C) and humidity conditions.Designed for DIN-rail mounting, the PWR-IE50W-AC is fanless, lightweight (0.64 kg), and has a high MTBF of over 1.6 million hours, making it ideal for mission-critical deployments. Built-in protections against over-voltage, over-current, over-temperature, and short circuit enhance reliability in industrial automation, transportation, utilities, and energy networks.

Questions & Answers

  • What is Cisco PWR-IE50W-AC used for?

    A 50 W industrial AC power supply providing regulated DC output for ruggedized switches and IoT gateways. It’s compact, DIN-rail mountable, and designed for reliable operation in harsh environments.

  • What input and output specs matter most?

    Confirm wide-range 100–240 VAC input and the DC output voltage/current required by your device. Review inrush and hold-up time, especially with UPS or generator feeds.

  • PWR-IE50W-AC vs PWR-IE65W-PC-AC—how to choose?

    Choose 50 W for small loads; choose 65 W when you need extra headroom or plan device additions. Both are industrial-rated and DIN-rail friendly.

  • Does it support protections?

    Yes. Over-current, short-circuit, and over-temperature protections are standard. Investigate downstream wiring if protections trip frequently.

  • Is it suitable for extended temperatures?

    Yes. It’s rated for industrial temperature ranges. Apply derating when ambient rises; ensure adequate ventilation and spacing.

  • How to wire safely?

    Use ferruled conductors, correct polarity, proper grounding, and strain relief. Label AC/L/N and DC +/– for quick service checks.

  • What about EMC and surge immunity?

    Industrial PSUs include EMC filtering and surge handling suitable for noisy cabinets near motors. Additional suppression may be used for extreme events.

  • Typical applications?

    Small IE switches, IoT gateways, serial servers, and protocol converters in automation cabinets.

  • How to calculate margin?

    Sum steady-state power and startup surges, then add 20–30% reserve. Consider future growth to avoid premature upgrades.

  • Maintenance checklist?

    Tighten terminals, dust the cabinet, verify output at load, and replace aging units on a planned cycle.
