PDU Power Distribution Unit Standard

Power Distribution Units (PDUs) are designed to safely distribute electrical power to multiple devices, with specifications varying by capacity, form factor, input/output configuration, and environmental tolerances. General OverviewPDUs provide a single electrical input and multiple outputs, typically as outlets, to power multiple devices in data centers or enterprise environments, ensuring reliable and scalable power distribution. They are available in basic, metered, and intelligent models, supporting both single-phase and three-phase power systems.

Electrical Specifications

Input Voltage and Frequency: Standard PDUs operate at 208/120 VAC, with input frequency options of 50 Hz ± 5% or 60 Hz ± 5%. Non-standard voltages can be customized. Power Capacity: PDUs range from small units with a few kVA to high-capacity units supporting 300 kVA to 2,000 kVA.

Eaton Power

Hub 2 PDUs support 400–1,250 kVA. Phase Compatibility: Available in single-phase or three-phase configurations, including Delta or WYE systems. Outlets: Basic PDUs can feature up to 54 outlets (vertical 0U) or 16 outlets (horizontal 1U/2U), with C13 and C19 outlet types commonly used.

Mechanical and Mounting Features

Form Factor: PDUs are designed for vertical (0U) or horizontal (1U/2U) rack mounting. Mounting Flexibility: Units include threaded inserts and mounting buttons for secure installation in standard racks or cabinets. Footprint and Density: High outlet density and compact form factors maximize space utilization in data centers.

Environmental and Operational Tolerances

Operating Temperature: 0°C to 40°C (32°F to 104°F) with ambient cooling air not exceeding 40°C; 24-hour average should not exceed 30°C. Storage Temperature: -100°C to 400°C (-330°F to 1040°F), with extended ranges available upon request. Humidity: 0% to 95% non-condensing.

Altitude: Operating up to 1,000 m (3,300 ft); storage and transport up to 12,200 m (40,000 ft),. Audible Noise: Compliant with NEMA-ST20 standards.

Safety and Compliance

Standards: PDUs are typically UL 1062 listed and tested to UL 1950 standards.

Hyper PD

Us also adhere to UL1062 and ISO9001 quality processes. Protection Features: Many PDUs include surge protection, thermal monitoring, and compatibility with breaker and metering technologies for enhanced safety and reliability.

Additional Features

Cable Management: Some PDUs feature cable tie-compatible outlets for secure cord retention. Monitoring: Intelligent PDUs allow proactive monitoring of thermal conditions and power usage to prevent failures and optimize energy efficiency. Material Options: Available in copper or aluminum construction to meet specific operational requirements.

PD

Us are critical for ensuring reliable, scalable, and safe power distribution in mission-critical environments, with specifications tailored to the size, load, and configuration of the data center or enterprise infrastructure.
