PWR-IE170W-PC-DC Description
The PWR-IE170W-PC-DC is a Cisco Industrial DIN-rail 170W low-voltage DC power supply for PoE-capable industrial switches in DC-fed cabinets. The supply takes a 12-54V nominal DC input (10.8-60V supported) and delivers 54VDC at 3.2A through a hardwired connection. The unit is rated IP20, operates from -40 to +75 C without derating and is approved for Class 1 Division 2 and Zone 2 hazardous locations.

Application Scenarios
A substation cabinet running on a station battery bus can power a PoE switch from the 12-54V DC feed through this supply. The 54VDC output feeds PoE ports directly and the Class 1 Division 2 approval covers the cabinet location.
The IE 2000U data sheet maps the 170W DC supply to PoE and PoE+ support on the switch ports in DC environments. The unit mounts on a DIN rail beside the switch.

PWR-IE170W-PC-DC and PWR-IE170W-PC-AC both deliver 54VDC at 3.2A for 170W, but PWR-IE170W-PC-DC takes a low-voltage DC feed of 12-54V nominal (10.8-60V supported), while PWR-IE170W-PC-AC takes AC 100-240V or DC 125-250V, so the cabinet feed decides between them. A PoE load that stays within 65W can use PWR-IE65W-PC-DC, which accepts DC 24-48V and outputs 54VDC at 1.2A. Loads above 170W need PWR-IE240W-PCAC-L at 240W, which takes AC only and, unlike PWR-IE170W-PC-DC, is not approved for hazardous locations, so a DC-fed site cannot swap it in.

Ordering Checklist
- IE 2000 hosts: Match the supply to IE 2000 switches such as IE-2000-8TC-G-B, which list PWR-IE170W-PC-DC= in the power supply table. Keep the switch and PoE load within the 170W budget.
- IE 3100 hosts: Use the supply with IE 3100 switches except IE-3100-4P2S-E, IE-3100-8P2C-E, IE-3100-3P1U2S-E and IE-3100-6P2U2C-E. PWR-IE170W-PC-DC= is not supported on those four PoE models.
