APC NetShelter Rack PDU Advanced (11K Series) provides reliable power distribution to IT equipment within server and/or networking racks. PDU level power metering provides power visibility and notification of potential overload. 4-in-1 combination outlets which can be used as either C13, C19, C15, or C21 outlets provide unparalleled deployment flexibility. Maximum outlet density with 42 outlets in a 2.2 in. (5.6 cm) wide form factor allows for more equipment in the rack. Outlets on the PDUs are color coded and labeled by breaker. Live Swap the NMC3 to minimize downtime in the unlikely event of an NMC power event. The rack PDU integrates with EcoStruxure IT through an NMC3 and can be accessed and configured via web, SNMP, and command line interface (CLI). A 10-foot (3-meter) input cord makes it easier for the PDU to reach the power supply. Rated to operate up to 60 C (140 F) at full load ensures reliability and availability even in today's high-density deployments. One gigabit Ethernet/network port (10/100/1000) enhances and standardizes network connectivity. Two link ports are available to cascade to up to 32 PDUs, with a network port sharing (NPS) feature to enable power sharing between Rack PDUs in the cascading group. Track or bill power usage confidently with 1% metering accuracy. Two environmental sensor ports allow for optional sensors (sold separately) to be connected. For data center deployments across multiple regions, these PDUs have the following certifications: UL, CE, CSA, UKCA, Nemiko, PSE, KC, China RoHS, RCM, and CMIM. This model’s input power cord is IEC-309 20 A 3P+N+PE and features 21 count C13/C15/C19/C21 combo outlets and 21 count C13/C15 outlets.
