APC AP7581 Rack PDU Extender Basic 2U 30A 208V
Overview
The APC AP7581 is a basic rack?mounted power distribution unit (PDU) designed to distribute a single high?current AC feed to multiple rack equipment outlets. Data center infrastructure teams and network engineers deploy this PDU extender to bring up to four 208?V receptacles to server, storage, network, and telecom equipment from a single branch circuit, simplifying power connectivity in rack cabinets. It is not a managed or switched PDU; rather, it provides straightforward outlet distribution where power monitoring or switching control is not required.
This unit accepts a 30?A, 200/208?V single input via a NEMA?L14?30P twist?lock plug and delivers up to approximately 4.992?kVA of capacity across four NEMA?L6?20R output receptacles. Its design provides a basic yet reliable method to extend a single branch power feed to multiple devices in racks requiring high?voltage distribution without the need for complex rack PDU management.
The AP7581 is built in a horizontal 2U form factor for standard 19?inch equipment racks. The included 28?foot flexible power cord enables placement above or below rack units while maintaining clearance and airflow inside the cabinet. Its horizontal mounting is suited for mid?mounting positions in racks where access to rear receptacles can facilitate equipment connections.
Because this unit is basic (non?metered, non?switched), it is appropriate for installations where power monitoring and remote control are not needed, such as branch office racks with predictable loads or secondary cabinets where a single circuit is distributed to multiple devices. It complements UPS systems and rack PDUs by splitting a single high?current feed into usable receptacles without active power conditioning.
This PDU extender is not suitable for roles requiring power metering, outlet switching, or network?based management capabilities. Installations needing advanced monitoring, per?outlet control, or redundant power feeds should select metered or switched rack PDU models instead.
