Cisco PWR-IE50W-AC-L - Industrial Ethernet 50W AC to DC Power Supply, 24VDC Output, DIN-Rail Mount, Lite Version - New
Cisco PWR-IE50W-AC-L 50W Industrial DIN-Rail Power Supply

The Cisco PWR-IE50W-AC-L is a compact industrial DIN-rail AC-to-DC power supply designed to power Cisco Catalyst IE3100, IE3200, IE3300, and IE3400 Rugged Series industrial Ethernet switches and the Cisco IR1101 Integrated Services Router per the official Cisco data sheets. It accepts 100–240V AC input (90–264V supported) at 50–60Hz and delivers 24VDC at 2.1A (50W max) with 88% typical efficiency and built-in over-voltage, over-current, over-temperature, and short-circuit protections. The slim 30mm-wide enclosure mounts to standard 35mm DIN rail, is rated IP20, and operates from −20°C to +70°C — supplied as open-type equipment for installation inside an appropriately rated industrial enclosure. Note: This is the Lite (-L) version for the Catalyst IE3x00 Rugged Series and is not interchangeable with the original PWR-IE50W-AC used by the legacy Cisco IE 3000 Series switches; PoE delivery is not supported — a 54VDC supply is required to provide PoE to downstream devices.

Cisco PWR-IE50W-AC-L - Key Features & Benefits

  • AC-to-DC Power for the Cisco Catalyst IE3x00 Rugged Series & IR1101: Converts wide-range 100–240V AC (90–264V supported) at 50–60Hz into 24VDC at 2.1A (50W max) to power Cisco Catalyst IE3100, IE3200, IE3300, and IE3400 Rugged Series switches and the Cisco IR1101 Integrated Services Router — all listed as supported PSU options in the official Cisco switch data sheets.
  • Compact Lite DIN-Rail Form Factor: Slim 30mm-wide DIN-rail enclosure weighing only 0.18 kg (0.39 lb) fits tight control cabinets — substantially smaller and lighter than the original PWR-IE50W-AC.
  • 88% Typical Efficiency with Multi-Layer Protection: Runs at 88% typical efficiency with over-voltage, over-current, over-temperature, and short-circuit protection built in per the Cisco data sheet.
  • Industrial Operating Range — Open-Type Equipment: Specified for −20°C to +70°C (−4°F to +158°F) at 5–95% RH non-condensing. Supplied as open-type equipment with IP20 ingress protection — must be installed inside an appropriately rated industrial enclosure.
  • Multi-Standard Safety & EMC Certified: UL/cUL recognized to UL 62368-1 (CSA C22.2 No. 62368-1) — current safety standard replacing UL 60950-1 — also recognized to UL 60950-1 / CSA C22.2 No. 60950-1, UL 508 listed, CE marked, NEC Class 2, CB scheme to IEC 60950-1, CISPR 32 / EN 55032, and FCC 47 CFR Part 15B.

Cisco PWR-IE50W-AC-L - Frequently Asked Questions (FAQ)

  • Which Cisco switches and routers work with the PWR-IE50W-AC-L?
    This PSU is listed as a supported power supply option in the official Cisco data sheets for the Cisco Catalyst IE3100, IE3200, IE3300, and IE3400 Rugged Series industrial Ethernet switches and the Cisco IR1101 Integrated Services Router. It is not designed for the legacy Cisco IE 3000 Series (IE-3000-4TC, IE-3000-8TC, and variants) — those switches use the PWR-IE50W-AC or PWR-IE50W-AC-IEC instead, which are larger units with different connectors and hazardous-location approvals.
  • Does this power supply deliver PoE to my switch's ports?
    No. The PWR-IE50W-AC-L outputs 24VDC at 2.1A (50W) and is not a PoE source. PoE-capable IE3x00 switches (such as IE-3300-8P2S, IE-3300-8U2X, IE-3400-8P2S, IE-3100-8P2C, IE-3100-6P2U2C) require a 54VDC PSU to actually deliver PoE — typically the PWR-IE65W-PC-AC, PWR-IE170W-PC-AC, PWR-IE240W-PCAC-L, or PWR-IE480W-PCAC-L depending on the PoE budget needed. This 50W unit is the right choice when PoE is not required or when only the switch itself needs to be powered.
  • What is the difference between PWR-IE50W-AC-L and PWR-IE50W-AC?
    The -L (Lite) version is the smaller, lighter, newer module (30mm wide, 0.18 kg, 88% efficiency) designed for the Cisco Catalyst IE3x00 Rugged Series and IR1101. The original PWR-IE50W-AC is larger (51mm wide, 0.64 kg), supports both AC and DC input, is Class 1 Div 2 / Zone 2 approved for hazardous locations, and is the PSU used with the legacy Cisco IE 3000 Series. The two units are not interchangeable.
