Power distribution unit APC NetShelter 9000 PDU 24 AC outlets (C13/C15/C19/C21), NEMA L6-20P, 200–208V, 20A, vertical 0U, black

APC NetShelter 9000 PDU is a vertical 0U power distribution unit designed for installation inside NetShelter racks and network cabinets. It provides 24 AC outlets in a mixed configuration (C13, C15, C19 and C21) and accepts a NEMA L6-20P input plug for 200–208 V nominal operation at up to 20 A. The unit includes a field-replaceable Network Management Card/Display Module (NMC) to reduce downtime, high-retention outlets for improved cord retention, and hydraulic magnetic circuit breakers for consistent trip performance across temperature variations. This model is certified to CUL, FCC 15 A, IEC 62368-1 and PSE standards.

Advantages

The field-replaceable NMC enables in-situ replacement of the network management module without removing the PDU from service, minimizing disruption. High retention outlets increase plug holding force to reduce accidental disconnects while remaining compatible with standard power cords. Select 9000 series features allow operation at elevated ambient temperatures up to 60°C at full load, supporting high-density deployments. Hydraulic magnetic circuit breakers help maintain reliable overcurrent protection across a wide temperature range.

Suitable for

• Data center racks and server cabinets requiring mixed outlet types
• Network closets and telecommunication cabinets with 200–208 V electrical infrastructure
• High-density equipment deployments where elevated ambient operation is needed
• Environments needing managed power with remote monitoring and control

How to use

Install the PDU vertically in a compatible NetShelter or 0U-capable rack position and connect the NEMA L6-20P input to an appropriate 200–208 V power source rated for 20 A. Plug equipment into the appropriate outlet types (C13/C15 for lower-power devices, C19/C21 for higher-power devices) ensuring cord compatibility. Use the integrated network management card and display module to configure monitoring, outlet control and alerts; if required, the NMC can be replaced in the field following the manufacturer's service instructions. Verify circuit breaker settings and ensure proper grounding before placing connected equipment into service.

Recommendations

Place the PDU in a rack location that allows adequate airflow and access to the NMC. Confirm that attached devices use compatible cords for C13/C15 or C19/C21 outlets, and avoid exceeding the 20 A branch capacity. For installations in higher ambient environments, choose the 9000 series models specified for 60°C operation and follow site electrical codes and thermal management best practices.
