Description
Tripp Lite 3 phase Monitored PDU / Power Distribution Unit offers real-time remote monitoring of voltage,
frequency and load levels via built-in network connection. PowerAlert interface supports custom notification of
user-specified remote conditions via email, secure web, SNMP, Telnet or SSH interface. PDU output current
consumption in amps is displayed per-phase via front panel lighted digital display and can be monitored remotely
to warn of potential overloads before critical IT mains breakers trip.
