The HP Power Distribution Rack (PDR) is designed for end-of-row power distribution for data centers using a zoned infrastructure. Each HP PDR (Figure 2) consists of an HP 10000-series rack configured with two 400-amp 42-pole (North America) distribution panels for a maximum of 84 output circuits. Each 42-pole distribution panel is protected by a 400-amp three-pole (3P) input circuit breaker (lower amperage configurations are acceptable as well). The distribution panels support 1P, 2P, and 3P breakers of a wide range of amperage ratings to allow a variety of three-phase or split-phase distribution configurations. Figure 2.

The Local display provides a readout of AC voltage/frequency/current, total power factor, total/peak kilowatts and kilowatt/hours at the distribution panel level. Remote monitoring provides comprehensive power data from individual branch circuits to a remote terminal and/or to other management systems. Remote monitoring is facilitated with the HP PDR Management Module (Figure 3), mounted inside the HP PDR. The HP PDR Management Module enables facility administrators to monitor PDR power status through a serial or network interface using RTU or TCP protocols. Figure 3.
