Specifications and Models of Computer Room Power Distribution Box

Computer room power distribution boxes, or PDUs, come in basic, metered, monitored, and intelligent models, offering scalable, reliable, and remotely controllable power distribution for server racks and data centers. Overview of PDUsPower Distribution Units (PDUs) are specialized devices designed to distribute electrical power from a single input source to multiple output receptacles in data centers and server racks. Unlike standard power strips, PDUs are engineered for high-density IT environments, providing robust construction, precise power management, and monitoring capabilities to ensure reliable operation of critical equipment.

Common PDU Models and Types

Basic PDUsProvide foundational power distribution without monitoring capabilities. Focus on robust construction and dependable performance. Ideal for environments where cost-effective, simple power delivery is sufficient.

Metered PDUsInclude local or remote metering to monitor power usage at the rack or input level. Help with load balancing and preventing overloads. Some models allow daisy-chaining multiple PDUs under a single IP address.

Monitored PDUsOffer real-time monitoring of power consumption at the rack or outlet level. Enable proactive management of energy usage and capacity planning. Often include LED displays for local monitoring.

Switched or Intelligent PDUsProvide remote on/off switching for individual outlets. Support scheduled power cycling, group reboot, and sequential socket switching. Allow full control and automation of power distribution, enhancing uptime and operational efficiency.

Technical Specifications

Input Voltage: Typically ranges from 120V to 415V AC, depending on the model and region. Current Capacity: Models support from 16A up to 400A for high-capacity applications. Outlet Types: IEC, NEMA, or universal outlets to accommodate diverse IT equipment.

Form Factor: Rack-mounted (1U–3U) or floor-mounted cabinets. Monitoring Features: Local LED displays, networked monitoring via SNMP, web interfaces, or APIs for integration with data center management systems. Safety and Reliability: Overload protection, surge suppression, and redundant power inputs for critical systems.

Use Cases

Small Network Closets: Basic or metered PDUs for simple power distribution. Enterprise Data Centers: Intelligent or switched PDUs for high-density racks, remote management, and energy optimization. Redundant Power Systems: PDUs with dual inputs or transfer switches to ensure continuous operation of critical servers.
