Middle Atlantic Multi-mount Rackmount Power, 16 Outlet, 20A, 3-Step Sequencing

Designed for professional-grade AV setups, broadcast suites, and data-intensive rack environments, the Middle Atlantic Multi-mount Rackmount Power delivers dependable power distribution in a compact, adaptable package. With 16 outlets arranged for flexible use, a 20A capacity, and a three-step sequencing feature, this unit helps you organize power efficiently while protecting your gear during startup and routine cycling. Its shallow 4" depth and 1U form factor make it an ideal solution for tight racks, while the ability to mount horizontally or vertically lets you tailor placement to your workspace. Whether you’re assembling a studio rig, live event system, or networked AV installation, this rack-mount power distribution unit (PDU) keeps power orderly, accessible, and ready when you need it most.

• Comprehensive 16-outlet power distribution with a robust 20A capacity, featuring sixteen NEMA L5-20R receptacles. This layout is ideal for housing multiple devices—AV processors, amplifiers, servers, media players, and auxiliary gear—in a single, centralized power hub.
• Three-step sequencing for smarter power management by staggering power delivery to connected devices. This sequencing helps manage inrush during startup, reduces electrical strain on equipment, and supports orderly power restoration after outages, which is particularly valuable for complex AV rigs and live production environments.
• Flexible mounting for any rack configuration with horizontal or vertical installation options. The adaptable mounting design enables clean integration into both switched and standalone rack layouts, streamlining cabling routes and aligning with your existing rack hardware.
• Compact, space-saving design features a shallow 4" depth and 1U height, preserving precious rack space for essential gear while keeping power distribution easily accessible. The compact footprint makes it suitable for compact control rooms, portable rack kits, and studios where space is at a premium.
• Reliable 120V power with professional-grade outlets uses a NEMA 5-20P input connector and 16 NEMA L5-20R outlets to deliver stable, high-current distribution in professional settings. The configuration supports clean, organized power delivery across a range of equipment without sacrificing outlet availability.

How to install Middle Atlantic Multi-mount Rackmount Power, 16 Outlet, 20A, 3-Step Sequencing

Installing this rack-mount power unit is a straightforward process designed to integrate smoothly into existing rack systems. Begin by selecting the mounting orientation that best suits your rack configuration—horizontal for side-by-side equipment or vertical for tight, stacked arrangements. Secure the unit to the rack rails using the appropriate hardware, ensuring it sits firmly and remains level for cable routing and airflow. Once mounted, plug the NEMA 5-20P input cord into a properly rated 120V, 20A power source, confirming that the circuit can handle the combined load of all connected devices. Distribute equipment across the 16 NEMA L5-20R outlets according to your operational priorities, giving critical devices priority placement on the first or preferred steps of the sequencing feature. After wiring, route power and data cables neatly to minimize cable clutter and improve airflow. Finally, configure or verify the 3-step sequencing order to align with your startup and shutdown procedures, then power on the system to observe that outlets provide power in the intended sequence. Periodically re-evaluate outlet assignments as your rack evolves, ensuring that new equipment remains within the protected and organized power distribution framework the unit provides.
