Rack power distribution units

13 June 2018 Power Electronics / Power Management

The RS Pro range has been bolstered with easily upgradeable power distribution units (PDUs) which give flexibility to retrofit power metering or networked power monitoring cost effectively and with minimal disruption.

The new family of PDUs offer versatile configurations, presenting an elegant solution for various types of racks. Choices include up to 24 Euro 2-pin (Shuko or NF 2P+T), UK 3-pin or IEC socket outlets, and with CEE 7/7 or British-Standard (BS) mains plug, 16 A or 32 A BS4343 plug, or IEC inlet. All configurations are available as basic PDUs, which can be upgraded to metered PDUs with an ammeter module, or fully monitored PDUs featuring an SNMP management module with Ethernet ports for remote power monitoring.

A basic PDU without power monitoring can be installed quickly and easily at little cost, which can then be upgraded in the future simply by adding the desired power monitoring module, which can be ordered individually. Because the modules are hot-pluggable, operators can start monitoring power usage without having to take equipment offline. They can also save by investing in one module to share among several PDUs for temporary fault finding or data gathering.

Adding the metering module to a basic PDU gives access to power data via the module’s built-in LCD panel. The more sophisticated, firmware-upgradeable SNMP management module allows users to monitor input current, voltage, power, energy consumption and power factor via a web interface, and to set SNMP traps and receive automatic email alerts about any faults. Daisy chaining allows full monitoring of up to five PDUs.
