The PWR-IE65W-PC-DC is a 65-watt, low-power, DC-to-DC power supply module designed specifically for Cisco Industrial Ethernet (IE) switches and routers. Unlike standard power supplies that convert AC wall power to DC, this unit takes an existing DC power source and converts it to the stable, clean DC power that sensitive networking equipment requires.

Key Features and Benefits

1. DC Input for Industrial Settings: This is its defining characteristic. It accepts a wide range of DC input voltages (commonly 12V, 24V, or 48V), making it ideal for environments where AC power is unavailable, unstable, or unsafe. Common sources include vehicle electrical systems, solar power setups, telecommunications battery plants, and industrial control panels.

2. Built for Tough Conditions: Industrial environments are tough. They can be subject to extreme temperatures, dust, moisture, and vibration. The PWR-IE65W-PC-DC is built to withstand these challenges, ensuring your network stays online where it’s needed most.

3. Hot-Swappable Redundancy: Many Cisco IE devices support dual power supplies. The PWR-IE65W-PC-DC is hot-swappable, meaning you can install or replace it without shutting down the switch. This allows for the creation of a redundant power system. If one power source fails, the second one instantly takes over, providing maximum uptime for mission-critical operations.

4. Compact and Efficient: Its small, modular form factor is designed to fit neatly into the power supply bay of compatible Cisco IE switches, saving valuable space in compact industrial enclosures.

Where Is It Used?

You’ll find this power supply hard at work in a variety of demanding scenarios:

• Transportation: In trains and buses for passenger Wi-Fi and surveillance systems.

• Manufacturing: On the factory floor, connecting PLCs, sensors, and robotic arms.

• Oil & Gas and Mining: In remote and hazardous locations where reliable power is non-negotiable.

• Smart Cities: Powering outdoor wireless access points and traffic management systems.

• Telecommunications: As a backup or primary power source in cell site routers.

The Bottom Line

The Cisco PWR-IE65W-PC-DC may not be the most glamorous piece of tech, but it is a critical component. It is the reliable heart that powers essential network infrastructure in the world’s most challenging environments. Therefore, it provides robust, flexible, and redundant DC power. As a result, it ensures that the connected systems we rely on can operate continuously, no matter where they are installed.
