PWR-IE170W-PC-DC Description
PWR-IE170W-PC-DC is a Cisco Industrial DIN-Rail 170W low-DC-to-DC power supply for industrial Ethernet PoE power designs that need a hardwired DC input source. It is listed as the Cisco ordering PID PWR-IE170W-PC-DC= and provides 54VDC, 3.2A output with 170W maximum output power from a DC 12-54V/23A nominal input, supporting a DC 10.8-60V input range for cabinet and DIN-rail deployments. The unit is IP20 rated, operates from -40C to +75C without derating, and appears in Cisco industrial switch power contexts including IE 2000U PoE/PoE+ DC environments and Catalyst IE3100 power-supply option tables where the documented unsupported-model footnote applies.

Application Scenarios
PWR-IE170W-PC-DC belongs in industrial cabinets where the available feed is low-voltage DC and the switch design still needs the 170W PoE output class.
Cisco IE 2000U documentation maps the 170W DC supply to maximum PoE and PoE+ port support in a DC environment, with separate outputs feeding the base unit and PoE input.
Operations teams can keep this SKU separate from PWR-IE170W-PC-AC= so a low-DC cabinet is not mistakenly staged with the AC or high-DC version.

- In a PWR-IE170W-PC-DC vs PWR-IE170W-PC-AC comparison, the key difference is input design: the DC model accepts DC 12-54V input, while the AC model accepts AC or high-voltage DC input.
- The PWR-IE170W-PC-DC difference from PWR-IE65W-PC-DC is output class. Both are low-DC PoE supplies, but the 170W model provides 54VDC at 3.2A while the 65W model provides 54VDC at 1.2A.
- For a PWR-IE170W-PC-DC vs PWR-IE240W-PCAC-L comparison, the 240W unit is an AC-input supply with a larger output class, so it does not replace the low-DC input role of PWR-IE170W-PC-DC.
- Buyers comparing which model to choose should start with input voltage, output wattage, hardwired installation, and the documented PoE power plan.
Selection Guide
1. Start with the cabinet voltage
Choose PWR-IE170W-PC-DC when the installation provides a low-voltage DC feed and the design requires a hardwired DIN-rail supply.
2. Keep the AC sibling out of low-DC BOMs
Use PWR-IE170W-PC-AC only when the cabinet is built for AC or high-voltage DC input. Matching the 170W output class does not make the input side interchangeable.
3. Separate 65W and 170W PoE planning
Select PWR-IE65W-PC-DC only where the lower 65W output class satisfies the switch and powered-device plan. Cisco separates the 65W and 170W PoE supply rows.
4. Confirm industrial compliance before assignment
Check Class 1 Div 2 or Zone 2, UL 508, IEC 61850-3, IEEE 1613, IP20, and temperature requirements before the supply is released for an industrial cabinet.
