Horizontal vs Vertical PDU: Airflow, Cable Bend Radius and Mounting Trade-Offs
TL;DR. A horizontal PDU (1U) mounts in 1U of vertical rack space and is used in shallow racks, wall-mount racks, or applications where rack space is constrained. A vertical PDU (0U) mounts in the rear vertical channel and occupies zero rack units, which is the standard for full-depth 42U or 45U d...Read more -
Monitored vs Switched PDU: Where Remote Control Actually Matters
TL;DR. A monitored PDU adds remote network access to electrical measurements; a switched PDU adds remote outlet switching on top. Switched PDUs enable hung server recovery without a service trip, sequenced startup to manage inrush current, and outlet-level access logging for SOC 2 and NIST SP 80...Read more -

What Is a Metered PDU and When Does Basic Monitoring Pay for Itself?
TL;DR. A metered PDU measures electrical parameters (voltage, current, kW, kWh) at the PDU input and often at the branch level, while a monitored PDU adds remote network access to those measurements. A switched PDU adds remote outlet switching. The four tiers are basic / metered / monitored / swi...Read more -

NEMA L5-30 vs L6-30: Choosing Locking Plugs for Rack PDUs in North America
TL;DR. For North American rack PDU installations, the two most common 30A single-phase locking configurations are NEMA L5-30 (125V / 30A / 2P3W grounding) and NEMA L6-30 (250V / 30A / 2P3W grounding). L5-30 is the standard for 120V circuits; L6-30 is the standard for 208V or 240V circuits. The tw...Read more -
