Overview
The PWR-IE170W-PC-AC is a high-reliability industrial power module built for extreme operational environments. It converts wide-range AC mains input into regulated direct current to drive Cisco Industrial Ethernet (IE) switches and connected PoE field devices. Engineered without moving cooling parts, it withstands severe thermal stress, mechanical vibration, and electromagnetic interference inside control enclosures.

Frequently Asked Questions (FAQ)
Does the PWR-IE170W-PC-AC require forced air cooling inside a closed control cabinet?
No, the unit utilizes passive convection cooling and operates fanlessly. However, engineers must maintain recommended clearance around the module’s heat dissipation fins inside the cabinet to support air convection across its full -40°C to 70°C operating thermal envelope.
How do I determine if 170W is sufficient for my Cisco IE switch setup?
Calculate the base power consumption of the switch chassis plus the total maximum wattage required by all connected PoE/PoE+ field devices. If total power consumption stays under 170W, this module is optimal. For higher PoE density, dual power supplies or higher-wattage units may be required.
Can the PWR-IE170W-PC-AC handle unstable AC input lines in remote plant locations?
Yes, the internal transformer accepts a wide 90V AC to 264V AC input range at 50-60Hz. It incorporates built-in surge, over-voltage, and short-circuit protection circuits to isolate sensitive switch electronics from grid fluctuations.
Selection Guide: When should I choose the PWR-IE170W-PC-AC over a DC-input power module?
Select this AC module when your installation site supplies standard mains power (110V/220V AC) directly to the control panel and lacks a centralized 24V/48V DC bus infrastructure. It converts AC mains to required switch rail voltages in a single integrated step.
What is the recommended installation procedure when replacing a failed power module in an active cabinet?
Isolate the incoming AC power feeder line before removing the module wiring. Unbolt the module from the DIN-rail or chassis mounting plate, insert the replacement unit, verify correct terminal polarity, re-engage wire retainers, and restore AC mains. Check status LEDs on the connected switch chassis to verify normal power delivery.
