The Smart PDU measures the electrical parameters per phase and outlet. Adjustable thresholds with alarms enhance the availability of connected devices. Additionally, the differential current per phase is monitored. The outputs can be switched individually either remotely or manually. An integrated display shows measurement values and the status of the PDU. Additional external sensors (temperature, humidity, and air pressure) can be connected to the communication interface. The PDU can be permanently installed in DIGITUS® racks or other housing systems with appropriate mounts.
