Allied Telesyn International AT-PWR4 Power Supply

The Allied Telesis AT-PWR4 Power Supply is a hot-swappable AC power module designed for the AT-MCR12 Media Conversion Rack-Mount Chassis, providing redundant power in a compact, 12-slot chassis. The unit ships preinstalled in the MCR12 and is built for quick replacement without powering down the system, aligning with Allied Telesis’ hot-plug power approach. It accepts AC input voltages of 100/220 VAC and is rated to deliver up to 80 W of power, making it suitable for global mains environments and uptime-critical deployments. As an AC redundant, plug-in power supply, AT-PWR4 enables maintenance or failure replacement without interrupting connected modules, helping keep network services running in edge and distribution scenarios that rely on the MCR12 chassis.
