HP solutions: PDR and pre-configured distribution cables

The HP Power Distribution Rack (Figure 10) consists of an HP 10000-series rack configured with two
400-amp, 42-pole distribution panels for a maximum of 84 output circuits. The HP Power Distribution
Rack allows either top or bottom entry of AC feed cable and is designed for convection (non-forced)
air cooling under full-load operation.

Each 42-pole distribution panel is protected by a 400-amp, three-pole (3P) input circuit breaker. 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.
The power infrastructure administrator can choose among several options that offer different levels of
load monitoring:
• Circuit monitoring panel provides local display of current loading at the distribution panel level.
• Enhanced monitoring provides local display of current demand, voltage levels, AC frequency, total
power factor, total/peak kilowatts and kilowatt/hours, and remote access capability with
RS-485 Modbus RTU communication port.
• Branch circuit monitoring system (BCMS) uses sensors to provide current and alarm conditions for
individual branch circuits off the distribution panel, with user-adjustable alarm levels and the
capability of remote control and status through an RS-485 Modbus RTU communication port
Monitoring at the distribution panel level allows
hundreds of branch circuits feeding tens of enclosures
to be monitored remotely through a single IP address.
HP offers a selection of power distribution cables
(Figure 11) for connecting the PDR to IT equipment rack
PDUs. The power distribution cables are available in
various lengths (Table 2) and preconfigured with
receptacles for simplified installation and
reconfiguration of a row of IT equipment racks.
