PWR-IE50W-AC Description
PWR-IE50W-AC is a Cisco Industrial DIN-Rail 50W hardwired power supply for rugged Ethernet and industrial access deployments that need 24VDC output from AC or high-voltage DC input. It is listed by Cisco as PWR-IE50W-AC=, supports AC 90-264V or DC 106-300V input, delivers 24VDC at 2.1A with a 50W maximum output, and is a no-PoE supply option used with Cisco industrial platforms such as IE 1000, IE 2000, IE 2000U, and IR809 power-adapter contexts.

Application Scenarios
PWR-IE50W-AC fits Cisco industrial access builds that need a 50W no-PoE DIN-rail supply with 24VDC output rather than the 54VDC PoE supply family.
Cisco IE 1000 and IE 2000 data sheets list PWR-IE50W-AC= as a 50W power-supply option with no PoE or PoE+ support, so replacement orders should not treat it as a powered-device budget source.
Cisco IR809 hardware documentation identifies PWR-IE50W-AC as the optional AC power adapter for sites that need 110/220V AC or 88-300V DC input rather than direct low-voltage DC wiring to the router.

- In a PWR-IE50W-AC vs PWR-IE50W-AC-L comparison, both are hardwired 50W no-PoE DIN-rail supplies, but PWR-IE50W-AC accepts AC or high-voltage DC input and carries Class 1 Div 2 or Zone 2 approval.
- The PWR-IE50W-AC difference from PWR-IE50W-AC-IEC is the input connector and input profile: PWR-IE50W-AC is hardwired and supports AC or high-DC input, while the IEC model is plug-in and AC-only.
- For a PWR-IE50W-AC vs PWR-IE65W-PC-AC comparison, the key difference is output role. PWR-IE50W-AC provides 24VDC no-PoE output, while PWR-IE65W-PC-AC provides 54VDC output with PoE support.
- Buyers comparing which model to choose should verify hardwired versus plug-in input, 24VDC versus 54VDC output, PoE requirement, and hazardous-location approval in the comparison table.
Selection Guide
1. Select the 24VDC no-PoE supply profile
Select PWR-IE50W-AC when the Cisco industrial device requires a 50W hardwired supply with 24VDC output and no PoE power budget.
2. Separate IEC plug-in installations early
Move the order to PWR-IE50W-AC-IEC only when the installation expects the IEC C14 plug-in connector instead of terminal-block source wiring.
3. Do not substitute it for PoE loads
Use PWR-IE65W-PC-AC or another Cisco-documented PoE supply when the BOM requires 54VDC PoE output rather than the 24VDC output on PWR-IE50W-AC.
4. Check industrial approval and platform context
Review Class 1 Div 2 or Zone 2 requirements, IP20 enclosure assumptions, and the Cisco platform document that lists the supply before releasing the quote.
Ordering Checklist

|
PID format |
Base PID PWR-IE50W-AC and Cisco ordering part PWR-IE50W-AC= |
Keeps the catalog record aligned with Cisco spare notation |
|
Input source |
AC 100-240V/1.25A at 50-60Hz or DC 125-250V/1.25A |
Avoids ordering an AC-only 50W variant for a high-DC cabinet |
|
Output requirement |
24VDC at 2.1A with 50W maximum output |
Prevents a 54VDC PoE supply or higher-wattage line from being substituted by habit |
|
Connection method |
Hardwired DIN-rail input connection |
Avoids expecting an IEC plug-in power cord on the base SKU |
|
Environmental fit |
IP20, -40C to +75C operating temperature, and no derating |
Matches the supply to enclosure and cabinet temperature assumptions |
|
Approval boundary |
Class 1 Div 2 or Zone 2 approval listed for PWR-IE50W-AC= |
Keeps the order separate from 50W variants not approved for hazardous locations |
|
Platform context |
Cisco IE 1000, IE 2000, IE 2000U, and IR809 documentation list this 50W supply in defined power contexts |
Prevents treating it as a generic DIN-rail converter |
