Huawei APM30H Outdoor Power Cabinet
The Huawei APM30H Outdoor Power Cabinet is an advanced outdoor power cabinet equipped with a heat exchanger, designed to provide stable -48V DC power for outdoor wireless base stations. It functions as a compact housing for Baseband Units (BBUs), transmission equipment, and power distribution modules in distributed or separated macro base station scenarios.
Technical Description for Huawei APM30H
The Huawei APM30H Outdoor Power Cabinet is engineered for fast network construction, integrating power conversion, battery management, monitoring, and temperature control in a single small-footprint unit.
- Thermal Management: Utilizes a heat exchanger (TMC11H technology in some versions) and internal/external fan systems to maintain optimal temperatures for sensitive electronics.
- Modular Architecture: Includes an embedded power subrack (such as EPU05A) that can be configured with multiple hot-swappable rectifier modules (e.g., PSU R4875G1 or EPW30-48A) to provide redundant DC power.
- Integrated Space: Typically provides a 5U installation space for customer equipment when a single BBU is installed and optional heaters are not used.

Core Internal Units for Huawei APM30H Outdoor Power Cabinet
These mandatory units form the base power and environmental control system of the cabinet:
- EPU05A Subrack: Distributes AC and DC power; models include EPU05A-06 (220V AC) and EPU05A-08 (110V AC).
- PSU Modules: Rectifier units that convert AC to DC, such as the Huawei R4850G2 or PSU R4875G1.
- FAN 02E / 02G: Cooling modules configured with fans and a cabinet control unit like the CCUB or CCUC.
- Outer Air Circulation Assembly: Includes a heat exchanger core and external fans to lower the operating temperature.
- BBU (Baseband Unit): Processes signals; supports models like the Huawei BBU3900, BBU3910, or BBU5900.
- PMU/SMU: Power and monitoring units (e.g.,SMU01C) that manage rectifiers and environmental signals.
Monitoring & Protection Materials of Huawei APM30H Outdoor Power Cabinet
Specific sensors and protection boards are integrated to ensure hardware safety:
- SLPU (Signal Lightning Protection Unit): Provides protection for trunk and monitoring signals; uses boards like UELP, UFLP, or USLP2.
- ELU (Electronic Label Unit): Automatically reports the cabinet type to assist in remote troubleshooting.
- Door Status Sensor: Monitors whether the cabinet door is open or closed for security alerts.
- Temperature Sensor: Typically monitors battery or internal cabinet temperatures (e.g., part number 33010296).
Optional & Auxiliary Components of Huawei APM30H Outdoor Power Cabinet
Depending on the deployment scenario (e.g., cold climates or high RRU counts), these materials may be added:
- AC Heater: Ensures internal components stay within an acceptable temperature range in cold environments.
- PDU03D-02 / PDU01D-01 : Power Distribution Units used to supply DC power to remote radio units (RRUs).
- SOU (Service Outlet Unit): Provides a maintenance socket to transfer AC power to customer equipment.
- GATM: An optional unit that supplies power to Tower Mounted Amplifiers (TMA) and monitors feeder current.
- EMUA/EMUB: Environment Monitoring Units for processing additional boolean alarm inputs.
Common Installation Materials
- Cables: Includes PGND (grounding), AC input power, DC output, fiber, and shielded network cables.
- Air Baffles: Installed in vacant slots below the BBU to optimize air duct performance and heat dissipation.
