Overview The PDU40TDUAL 3.8kW Single-Phase Dual-Circuit 120V Basic PDU works as two independent PDUs in a single housing, perfect for networking, telecom, security, audio/video and sound reinforcement applications. Ideal for high-density network equipment with dual redundant input cables, it features 40 NEMA 5-15/20R outlets split evenly into two separate power circuits. Each power circuit, including its input plug, power cord, breaker and outlets, is color-coded black or gray for easy identification. Both 10-foot power cords feature NEMA L5-20P input plugs and come with optional adapters to convert them to NEMA 5-20P plugs, which are not color-coded. Connect the plugs to separate mains input power sources, generators or protected UPS systems to distribute AC power to connected equipment. The switchless design prevents an accidental shutdown, which could lead to costly downtime. Dual 20A circuit breakers protect connected equipment from dangerous overloads. The 70-inch all-metal housing supports toolless 0U vertical mounting in EIA-standard 19-inch racks, as well as on a wall or workbench or under a counter with user-supplied hardware.
