Procurement Decisions

PDUs and UPS units are both core parts of rack power infrastructure, but they serve completely different functions — and people often confuse the two....

Three-phase PDUs are gaining traction in modern data centers, driven by soaring rack power density for AI, HPC and high-performance server hardware. AFCOM’s 2025 State...

Yes, basic PDUs are often the better choice for specific data center architectures: low-density racks, edge sites, high-security environments, and deployments with limited management needs....

The terms “1U” and “2U” describe how much vertical rack space a horizontal power distribution unit (PDU) occupies. The measurements follow the EIA-310-D industry standard,...

Metered power distribution units (PDUs) measure and display power usage at the rack, while unmetered PDUs distribute power to connected equipment without built-in power monitoring....

The three main types of rack power distribution units (PDUs) are basic PDUs, metered PDUs, and switched PDUs. They differ in monitoring capabilities, remote control...
