Legrand Raritan iX Rack-PDU 0U with 18x C13 / 18x HDOT Cx, 3-phase 400V 32A, Input Metered (PX4-1699-E7V2)

Three-phase power distribution in the data center — why 22 kVA makes the difference

In professional data centers with increasing rack density, a robust three-phase power distribution is indispensable. The Legrand Raritan iX Rack-PDU 0U (PX4-1699-E7V2) delivers the necessary capacity for high-density server cabinets with 22.2 kVA and 36 outlets (18x C13, 18x HDOT Cx). The three-phase architecture evenly distributes the load across all three phases (Alternating Branch), avoids load spikes and uses the available capacity optimally. Billing-grade metering (Class 0.5) and full remote management via Gigabit Ethernet provide maximum transparency and control. The IEC 60309 inlet (3P+N+PE, 32A) with a 3 m power cord enables direct connection to three-phase power sources. Six overload-protection breakers with 10 kAIC interrupting capacity protect connected devices reliably. The mechanical plug latching on all 36 outlets prevents accidental unplugging and significantly increases operational safety during live operation.

What advantages does the PX4-1699-E7V2 offer compared to single-phase rack PDUs?

Single-phase PDUs are often sufficient for smaller installations — however, in high-density environments they quickly reach their limits. The three-phase Legrand Raritan PX4-1699-E7V2 provides many times the capacity of a single-phase PDU with 32A and 22.2 kVA. The 36 outlets with mechanical plug latching enable the powering of entire racks from a single PDU. Six 10 kAIC breakers reliably protect connected equipment from overload. The hot-swappable controller allows maintenance during live operation — a decisive advantage in environments with high availability requirements. The vertical 0U form factor occupies no rack units and thus maximizes capacity for servers, switches and storage systems. In data centers with growing device density, side mounting also reduces cable management effort and improves airflow within the cabinet — an important factor for cooling efficiency and the sustainable operation of the IT infrastructure.

How can the Raritan iX PDU be integrated into existing DCIM systems?

The Legrand Raritan PX4-1699-E7V2 supports a wide range of open interfaces for seamless integration into existing DCIM platforms and monitoring systems: Redfish API, SNMP v2/v3, MODBUS-TCP, JSON-RPC and HTTP(s) are available for automated data collection. PDU Linking can combine up to 8 PDUs into a single management unit. Additionally, up to 32 PDUs can be cascaded over a single Ethernet port — ideal for large data centers that require a scalable and IP-efficient infrastructure. The dual Gigabit Ethernet connection with optional Wi‑Fi provides a redundant network link and minimizes the risk of connectivity loss. Environmental sensors for temperature, humidity, airflow, differential pressure, water leak and motion extend monitoring capabilities beyond power alone. Automated provisioning via TFTP, DHCP and USB flash drives accelerates commissioning and reduces manual configuration effort. Data logging via HTTP/S or MQTT enables complete documentation of all measurements for compliance evidence and energy audits. The maximum operating temperature of 60 °C at full load confirms the PX4-1699-E7V2’s reliability even in thermally demanding environments. CE certification ensures conformity with European safety standards. With the iOS and Android app, administrators also have mobile access at any time to measurement data, alarms and configuration settings — for maximum flexibility and fast response times in daily data center operations. The combination of three-phase high-power distribution, precise billing-grade energy measurement and extensive remote management capabilities makes the Legrand Raritan PX4-1699-E7V2 a future-proof solution for professional data centers and server rooms of any size.
