The Raritan PX4-5917-E7M28V2 is a high-performance, vertical-mount intelligent three-phase rack PDU (400 V / 32 A, Wye) engineered for modern data centre power distribution. It features 24 IEC outlets (12 locking IEC C13 and 12 locking HDOT Cx outlets), all of which are individually switchable and individually metered, enabling precise per-outlet control and monitoring. The PDU provides billing-grade metering accuracy (±0.5%) and comprehensive power quality analysis, including harmonic distortion, power factor, inrush current, and voltage dips and swells. Thanks to the iX9 hot-swap controller, dual Gigabit Ethernet, optional Wi-Fi, and app-based control (iOS/Android), it enables reliable remote monitoring and efficient energy management. With daisy-chain capability (up to 32 PDUs), environmental monitoring (up to 32 sensor functions), and SecureLock-compatible outlets, it is well suited for scalable and high-availability rack environments.
