Huawei Power Supply PAC1000S56-EB 1000W AC & 240V DC Power Module

The Huawei PAC1000S56-EB is a high-efficiency, dual-input enterprise power module designed specifically for mission-critical networking hardware, such as CloudEngine series data center switches. Delivering a robust output power of up to 1000W, this power supply supports both standard AC grid inputs and 240V high-voltage DC (HVDC) inputs, offering enterprises a flexible and energy-efficient path toward modern green data center architectures.

Built inside a compact 66mm width mechanical form factor, the module features a specialized back-to-front airflow configuration where thermal exhaust is expelled directly from the power panel side. This targeted design ensures seamless integration into environments utilizing strict hot/cold aisle isolation.

• Dual AC and HVDC Input Support: Universally compatible with alternative current (AC) lines and high-voltage direct current (240V DC) supplies, minimizing internal power conversion losses and boosting overall PUE
• 1000W High-Capacity Output: Provides a stable, high-density 56V DC secondary output up to 1000W, safely accommodating high PoE power allocations or complex hardware processing boards
• Optimized Airflow Path: Engineered with a back-to-front cooling system (power panel side exhaust) to match corresponding airflow configurations of target switches, preventing internal hot spots and recirculation
• Hot-Swappable Mechanism: Allows quick, toolless replacement or addition within dual or multi-power module switch chassis without interrupting active network traffic or causing downtime

This indicates that the cooling fan inside the module pulls air from the inner chassis connector side and expels the hot exhaust out through the power panel side (where the power cord plugs in). It is crucial to match this with a switch that shares the exact same back-to-front airflow orientation to ensure effective thermal management.

By default, the power module package contains the core power supply unit and standard documentation. Power cords with localized plug terminations (such as C13/C14 or specific country designs) must be ordered separately based on your data center PDU interface standards.

The PAC1000S56-EB modules are secured inside original Huawei individual industrial packaging, embedded within custom anti-static foam inserts to protect sensitive electronics against electrostatic discharge and mechanical shocks during transit. We coordinate international distribution through leading air express services including FedEx, DHL, and UPS. Shipments are processed quickly, arriving at most international corporate sites within 3 to 5 business days with full door-to-door tracking documentation.
