IP-addressable power distribution unit cuts energy costs and improves system reliability
Solid State Supplies  has introduced an IP-addressable power distribution unit (PDU) that enables remote control and monitoring of various equipment including fan trays. It enables start-up sequencing and monitoring of the true-RMS current drawn from each outlet, with user-defined thresholds linked to alerts that are automatically communicated via email or as SMS messages. In addition to user-defined on/off sequencing, the Smart Switched PDU is compatible with http, https, SNMP, DHCP and UDP protocols.
Closely controlling the operation of fans improves system-level thermal management, leading to greater reliability. It also avoids the need for over-provisioning the thermal management system by ensuring that only the fans required at the time are switched on. This optimises system performance and minimises energy consumption. Used as a low cost alternative to AC fan trays with built-in intelligence, the PDU is designed for 19-inch rack mounting in data centres and other electrically intensive applications.
