Dimensions of rack-mounted PDUs for oil and petrochemical applications

Rack-mounted PDUs typically range from 0U to 2U in height, with widths around 2 inches for narrow models, and are designed to fit standard 19-inch racks, offering flexible mounting for industrial and data center environments.

Standard Form Factors

Rack-mounted PDUs are designed to fit standard 19-inch racks commonly used in industrial and petrochemical facilities. The height of PDUs is measured in rack units (U):

• 0U PDUs: Mounted vertically along the side of the rack, often high-density with 24, 42, or 48 outlets, and a narrow width of approximately 2 inches, allowing multiple PDUs in a single rack space (Eaton G4 series) .
• 1U–2U PDUs: Mounted horizontally at the top or bottom of the rack, providing a more traditional layout for basic or metered PDUs . The cord length is typically 1 to 1.5 meters routed within the rack, so the AC power source should be within 2 meters of the rack .

Mounting and Outlet Configurations

• Vertical PDUs (0U): Ideal for high-density applications, allowing outlets to be distributed evenly along the rack height. They often include C13, C19, or combined C39 outlets to accommodate various plug types .
• Horizontal PDUs (1U–2U): Suitable for smaller racks or network closets, with outlets arranged in a single row. Some models offer switched or metered outlets for load monitoring and remote control .
• Dual input PDUs: For critical applications, PDUs may include two independent power inputs with automatic transfer switches to maintain uptime during power loss .

Industrial Considerations

For oil and petrochemical environments, PDUs must meet high operating temperature ranges, robust insulation, and safety certifications. Many industrial PDUs are configurable to isolate circuits with separate breakers and can include environmental sensors for temperature, humidity, and airflow monitoring .

Summary

• Width: Typically 2 inches for vertical 0U PDUs; standard 19-inch rack width for horizontal units.
• Height: 0U (vertical), 1U–2U (horizontal).
• Outlet types: C13, C19, or combined C39; basic, metered, or switched configurations.
• Mounting: Side-mounted (0U) or top/bottom-mounted (1U–2U).
• Industrial features: High temperature tolerance, dual inputs, environmental monitoring, and circuit isolation. These specifications ensure that rack-mounted PDUs can be safely and efficiently deployed in oil, petrochemical, and industrial data center applications, providing reliable power distribution while accommodating high-density equipment layouts.
