This ATEN eco PDU is a rack-mounted power distribution unit rated at 32A with 24 outlets, built for data centre and server room racks that need reliable, monitored power distribution across many devices. "Metered & Switched" means it reports real-time power consumption for capacity planning and energy monitoring, and lets each outlet be individually switched on/off remotely — useful for remotely power-cycling a hung server or scheduling non-critical equipment to shut down outside business hours to save power. It's an infrastructure component for IT professionals managing rack environments rather than an end-user product, typically installed alongside servers, switches and other rack-mount gear in a comms room or data centre.
