• Applicable to 5G AAU devices, including Air 6488 and similar models (please confirm specific compatibility with your equipment)

• Part of the RNT447 series, which also includes models such as 32/02, 31/03, 30/02, 38/02, and 39/01 for different power and application requirements

Technical Specifications

Application Scenarios

• Outdoor Macro Cell Base Stations: Connects RRU to -48V DC power supply for reliable outdoor operation

• Distributed RAN (D-RAN): Used for power transmission between BBU and RRU to ensure stable power supply

• 5G Base Station Deployment: Provides power connection for 5G AAU devices in high-density, high-power scenarios

• Base Station Maintenance and Upgrades: Ideal for replacing aging power connectors in existing Ericsson equipment

Purchasing Recommendations

• Confirm your equipment model: Verify that your RRU, AAU, or BBU is compatible with RNT447 series connectors before purchasing.

• Standard choice for 4G/LTE RRU: RNT447 37/01 is a reliable standard option for Radio 22xx, Radio 44xx, and RRUS12 series.

• For 5G AAU deployment: Suitable for Ericsson Air 6488 and similar 5G AAU devices (confirm compatibility with your specific model).

• Consider higher-current variants: For high-power applications, consider RNT447 38/02 or 39/01 models which offer enhanced thermal performance and current capacity.

• Not compatible with non-Ericsson equipment: This connector is specifically designed for Ericsson AAU/RRU equipment and may not fit other brands.

• All products are inspected for appearance and electrical performance before shipment.
