The PDU33105 is ideal for data centers, server rooms, and enterprise network closets where reliable power delivery and visibility are paramount.
This PDU is designed for 3-phase power systems operating at 208 VAC. It features a NEMA L21-30P input plug, commonly found in 30A, 3-phase, 208V circuits. The unit provides 44 outlets: 2x NEMA 5-20R (20A), 36x IEC-320 C13 (10A), and 6x IEC-320 C19 (16A). It is compatible with standard 19-inch server racks and supports cascading for expanded power management. Its operating temperature range of 23-140°F (-5 to 60°C) makes it suitable for various deployment environments.
The PDU33105 mounts vertically in a 0U space within a standard server rack, utilizing the included mounting brackets. The power cord is 10 ft long, providing flexibility in placement. The unit supports Ethernet (RJ45) for network management and a serial (RJ45) port for direct console access. Overload protection is provided via three 20A circuit breakers. Ensure the input power source matches the NEMA L21-30P connector and the 208 VAC, 3-phase requirement. The input current is rated at 30A, but derated to 24A for continuous operation.
