What is a rack PDU?
A rack PDU (Power Distribution Unit) is a power distribution device designed to distribute power to computers, servers, network switches and other IT equipments in a rack in either vertical (0U) or horizontal (1U or more) position. PDUs come in a variety of model from Basic PDU, Metered PDU, Monitored & Switched PDU.

Which power distribution unit is best for your application?

Basic PDU : Basic PDUs are designed for cost efficient and reliable power distribution in data center. It can be used in an A/B Circuit configuration but does not supply any extra features other than power distribution.

Metered PDU : It has a LED status display built into unit itself. This feature allows current local monitoring for each PDU. It easily prevents circuit overloads during equipment installation and allows users to plan the capacity based on actual real time current monitoring or when load balancing an A/B feed installation.

Monitored & Switched PDU : It is Intelligent PDU / Smart PDU / IP PDU / Monitored PDU. It has the ability to remotely monitor the state of the PDU, the current draw down to the outlet level and report history trends and provide remote on/off outlet switching functionality. Access to these models is typically accomplished through dedicated remote access software, Web-based GUI or 3rd Party DCIM via SNMP V2/V3.
