Dimensions of Smart PDUs for Security Applications

Smart PDUs for security applications are typically available in standard rackmount sizes, including 1U to 3U heights, with vertical and horizontal configurations to fit standard 19-inch racks, and depths ranging from 10 to 30 inches depending on model and features.

Standard Form Factors

Smart PDUs are designed to fit within standard 19-inch server racks and are available in both horizontal (rackmount) and vertical (zero-U) configurations. Horizontal PDUs usually occupy 1U to 2U of rack space, while vertical PDUs are mounted along the side of the rack without consuming traditional U space, making them ideal for high-density environments . Depths vary depending on the number of outlets, integrated monitoring, and security features, typically ranging from 10 to 30 inches .

Security Integration

For security-sensitive applications, Smart PDUs often include electromechanical locking systems and RFID-enabled access control. For example, nVent Enlogic PDUs integrate with Security Access Control eHandles, allowing the PDU to act as a hub for both power monitoring and cabinet access management . These features do not significantly alter the standard rack dimensions but may require additional clearance for cabling and handle operation.

Electrical and Mounting Considerations

Smart PDUs are available in single-phase and three-phase configurations, with current ratings up to 100A per unit . Vertical PDUs are ideal for racks with limited horizontal space, while horizontal PDUs are suitable for smaller racks or where outlet accessibility is critical . Many models include hot-swappable controllers, OLED displays, and multi-sensor ports, which may slightly increase depth but maintain standard width and height compatibility .

Summary

• Width: Standard 19-inch rack compatible
• Height: 1U–3U for horizontal; zero-U for vertical
• Depth: 10–30 inches depending on features
• Mounting: Horizontal or vertical
• Security Features: RFID, electromechanical locks, integration with access control systems
• Electrical: Single-phase or three-phase, up to 100A These dimensions and configurations ensure that Smart PDUs can be deployed in secure IT environments, providing both power distribution and access control without compromising rack space or operational efficiency .
