Product description
DK PDU managed, high-end power distribution incl. energy measurement, switching and monitoring functions per output slot, with network interface and display, WLD: 44x1495x70 mm, IEC 60 320: 12x C19
Feature: Per-output energy measurement with monitoring translates to immediate business impact: precise cost allocation, capacity planning, and fault detection. Application: IT racks in data centers or colocation facilities benefit from granular energy data, enabling you to identify hot spots and optimize workload placement. The 12 C19 sockets and 400 V input deliver scalable power for multi-server configurations, while the 3-phase infeed and 22 kW rating accommodate dense IT deployments. Feature: Integrated display and rotatable controller enable on-site status checks without tools. Business impact: faster troubleshooting and reduced mean time to repair. Application: IT rooms with limited console access can rely on the built-in display and web interface for rapid status checks across outputs. Feature: Built-in network interface with two RJ45 ports, one PoE, enabling remote management and PDU web server power via PoE. Business impact: continuous monitoring and reduced downtime through remote configuration and alerting. Application: data centers seeking centralized rack power management across multiple frames. Feature: Compatibility with VX IT enclosure frames and zero-U mounting enables efficient use of rack space and tool-free installation in tight IT environments. Business impact: faster deployment and improved rear cabling management. Application: rack installations in telecom rooms, edge data centers, and enterprise IT closets. Feature: Optional Type 3 overvoltage protection with interchangeable arresters, residual current measurement per feed, and CAN bus sensor support for ambient monitoring. Business impact: enhanced protection and compliance with monitoring requirements. Application: critical IT deployments needing robust surge protection and environmental awareness. Feature: Protocols and security options include HTTP/HTTPS, SSL, SSH, Telnet, and NTP, plus 12 outputs monitored via a 2x RJ45 interface. Business impact: secure, auditable access and accurate time synchronization for logs. Application: data centers requiring compliant, traceable power management.
