Cisco PWR-IE50W-AC-L - Industrial 50W AC-DC Power Supply, 24V DC Output, 30mm DIN Rail, Fanless Lite - Cisco Refresh

The Cisco PWR-IE50W-AC-L is a fanless, compact 50W AC-to-DC industrial DIN-rail power supply that supplies the 24V DC switch logic input on Cisco Catalyst Industrial Ethernet rugged switches — including the IE3000, IE3100, IE3200, IE3300, and IE3400 Rugged Series. Output is a regulated 24V DC nominal at 2.1A (50W max), drawn from a universal 90–264V AC mains input (100–240V AC nominal, 50/60 Hz). Important: per Cisco datasheet this part does NOT supply PoE/PoE+ — the IE3200, IE3300, and IE3400 platforms require a separate 54V DC supply (e.g. PWR-IE65W-PC, PWR-IE170W-PC, PWR-IE240W-PCAC-L, or PWR-IE480W-PCAC-L) for PoE operation on downstream ports. The Lite (-L) variant is silent fanless, uses a terminal-block input, and is NOT approved for hazardous-location installations (use PWR-IE50W-AC= for Class 1 Div 2/Zone 2 deployments). This unit is supplied as Cisco Refresh — Cisco-certified remanufactured. IP20 rated — must be installed inside a suitable enclosure.

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

• 50W AC-to-DC Conversion, Universal Input: Delivers a regulated 24V DC nominal output at 2.1A from a 90–264V AC mains input (100–240V AC nominal, 50/60 Hz). A single SKU covers North America, EMEA, and APAC deployments without reconfiguration.
• 88% Typical Efficiency: 88% typical efficiency per Cisco datasheet (test conditions not specified in the public document) — reduces cabinet heat load relative to lower-efficiency variants in the same family.
• Fanless Lite Design — Silent Operation: No fan, no moving parts — eliminates a mechanical wear point and audible noise; ideal for quiet control rooms, sealed enclosures, hospitality cabinets, and noise-sensitive deployments.
• Ultra-Compact 30mm-Wide DIN Rail Footprint: Just 30 mm wide × 75 mm high × 89.5 mm deep (1.18 × 2.95 × 3.52 in), 0.39 lb (0.18 kg) — substantially smaller than the standard PWR-IE50W-AC=. Snaps onto standard 35 mm DIN rail for tight cabinet builds.
• Industrial Operating Range with Defined Derating: Operates from -20°C to +70°C ambient with storage -40°C to +85°C; published power derating of 3.33%/°C above +55°C and 2%/°C below -10°C. 5–95% RH non-condensing humidity.
• Built-In Protection & 20ms Hold-Up: Built-in over-voltage, over-current, over-temperature, and short-circuit protection; 20 ms hold-up time at 100% load rides through brief AC dropouts.
• Cisco-Certified Refresh: Supplied as Cisco Refresh — Cisco-certified remanufactured to original factory specifications.

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

• Will the PWR-IE50W-AC-L power PoE on my IE3200, IE3300, or IE3400 switch?
  No. Per the Cisco Industrial DIN-Rail Power Supplies datasheet, the PWR-IE50W-AC-L has no PoE/PoE+ support — it provides 24V DC for switch logic only. The IE3200, IE3300, and IE3400 DIN-rail platforms require a separate 54V DC power supply (such as PWR-IE65W-PC, PWR-IE170W-PC, PWR-IE240W-PCAC-L, or PWR-IE480W-PCAC-L) for PoE operation on downstream ports.
• Which Cisco switches is this power supply compatible with, and what does it actually power?
  The PWR-IE50W-AC-L supplies the 24V DC switch logic input on the Cisco Catalyst IE3100, IE3200, IE3300, IE3400 Rugged Series and the Cisco IE3000 family. It powers the switch itself; it does not power PoE downlinks (see PoE FAQ above) and is not a PSU for Cisco Catalyst (non-IE) enterprise switches or Cisco IP phones. Always confirm against your switch's hardware installation guide before deploying.
• What's the difference between the PWR-IE50W-AC-L, PWR-IE50W-AC, and PWR-IE50W-AC-IEC?
  All three deliver 50W (24V DC @ 2.1A). The -L (Lite, this part) is fanless, very compact (30 mm wide), uses a terminal-block input, and is NOT approved for hazardous locations. The PWR-IE50W-AC= is a fan-equipped, larger 51 mm-wide unit that accepts both AC (90–264V) and high DC (106–300V) input and IS approved for Class 1 Div 2/Zone 2 hazardous locations. The -IEC variant uses an IEC 60320 C14 inlet instead of a terminal block; AC-only, also not haz-loc approved.
• Can the PWR-IE50W-AC-L be used in hazardous-location installations?
  No. Per Cisco datasheet the PWR-IE50W-AC-L is not approved for hazardous-location installations. For Class 1, Division 2 / Zone 2 deployments, select the PWR-IE50W-AC= (which is haz-loc approved) instead.
