Photovoltaic inverter is designed to accommodate up to six separate sub-arrays for enhanced siting flexibility. PV sub-arrays can be placed on multiple roof planes, thereby requiring 43% less roof space than competitive inverters with higher voltage string configurations, according to the manufacturer.

Power distribution strips are said to bring advanced control and visibility to rack-level power distribution. The power strips are available in multiple configurations that provide a choice of capacities, number of receptacles and monitoring and control capabilities to meet the power management requirements of rack-mounted equipment. They internally connect output receptacles to the power bus via printed circuit board design and are available with monitoring only and monitoring and control capabilities.

Serial encrypting transceiver is designed to protect existing and new communications links between power control centers, electrical substations and generating plants. A cyber attack, for example, can secretly monitor sensitive information on data links, or send messages to operate equipment or change settings. Attackers could steal data that would identify biggest customers, usage patterns, delivered power quality, and production rates, or to identify physical targets. The transceiver protects critical infrastructure from attack and complies with industry requirements and recommendations. It uses encryption and session authentication, and locks out unauthorized control. For more information on the 3021 from SEL, click here .

Power distribution unit has power monitoring function to support rack-mount applications with either single-phase or three-phase power, as well as full-rack power utility ranging from 7,300 watts up to 22,000 watts. Available PDUs include single mount models with 39 receptacles and dual mount models with 78 receptacles. For more information on PDUs from Hewlett Packard, click here .
