Monitored PDUs offer the same features as metered PDUs, with the addition of a built-in network interface and included software. The interface and software allows managers to remotely view PDU load levels via an Ethernet network connection. Managers can view the increased load from the remote computer and take proactive steps to increase input capacity (with the addition of more or larger UPS systems or additional utility circuits). They can also view user-defined PDU alarm conditions (including input/output voltage and load thresholds) using the included software. Tripp Lite monitored PDUs are available in both single-phase (single-phase in and single-phase out) and 3-phase (3-phase in and single-phase out) configurations.
