Middle Atlantic MPR Module, 20 A, Duplex, ISO Ground – 2 x NEMA L5-20R, 115V Power Distribution for MPR Series

Engineered for professional AV installations and demanding commercial environments, the Middle Atlantic MPR Module delivers dependable, scalable power distribution exactly where you need it. This 20 A duplex ISO Ground module is built from steel and finished with a black textured powder coat to withstand the rigors of racks, stages, and control rooms. Featuring two NEMA L5-20R outlets, 115V input power, and a unique genderless connector, it offers a compact, modular solution that integrates seamlessly with the renowned MPR Series raceways. The MPR Module is designed to be customized to match the exact needs of any project—whether you’re configuring a compact desktop rack, a touring rig, or a fixed installation in a broadcast environment. With its modular philosophy, you can expand or reconfigure power distribution as your system evolves, saving time during installation and minimizing downtime during upgrades.

• Modular customization for project needs: The MPR Series is designed to be assembled module by module, allowing you to tailor power distribution to fit your exact equipment lineup. This MPR Module provides 20 A of capacity across two outlets (2 x NEMA L5-20R) and can be combined with additional MPR modules to create a power strip that precisely matches the scope and layout of your installation. Its modular nature makes it simple to add circuits, reconfigure outlet layouts, or expand capacity as your system grows, without replacing the entire power distribution solution.
• Rugged steel construction with durable finish: Built to survive the daily stresses of rack rooms and live environments, this module uses a steel chassis with a black textured powder coat finish. The robust construction helps resist impact, corrosion, and wear from frequent instrumentation changes, plugging and unplugging, and rack movement. The finish not only looks professional but also conceals scuffs that are common in busy installations, keeping the system looking clean and professional over time.
• ISO Ground for cleaner power delivery: The ISO Ground design isolates the ground path to minimize electrical noise and interference that can affect sensitive audio, video, and control gear. By reducing hum and ground-loop issues, your critical equipment—mixing consoles, reference monitors, media servers, and real-time controllers—can perform more consistently and with improved clarity. This feature is particularly valuable in studio environments, broadcast suites, and live production settings where clean power is essential.
• Genderless connector for simplified wiring: The MPR Module uses a unique genderless connection that streamlines field wiring and reduces inventory headaches. Installers can mate modules and raceway sections without worrying about gendered insertions, speeding up assembly and minimizing the chance of mis-wiring. This design choice also simplifies maintenance and future upgrades, since replacements or expansions can be completed quickly and accurately.
• Easy integration with MPR Series raceways: Compatibility with the MPR Series ensures a seamless, integrated power distribution system. The module is engineered to slot directly into MPR raceways, aligning with existing module interfaces and the system’s overall mechanical and electrical standards. This cohesion helps you achieve a neat, professional installation with predictable performance and straightforward servicing, which is highly valued in installations that require repeatable results across multiple rooms or venues.
