Installation

Based on different application scenarios, the power input and device installation for RAK9105U are different.

Smart Power Control Applications

In this application scenario, the RAK9105U is integrated between the power supply and the power distribution device. By configuring its power output interface, it controls the power switch of connected distribution devices, such as gateways, CPE devices, routers, and other equipment.

Figure 1: Power Supply Installation

Device Connection

1. Connect the power input interface of the device (such as gateways, CPE devices, routers, etc.) to the Output2 interface of the RAK9105U using a DC cable.
2. Connect an external power supply (9–24 V) to the Input DC 12  V interface of the RAK9105U using the provided DC cable.
3. Enable the external power supply to power the RAK9105U.

NOTE

• When connecting a device to the RAK9105U, use appropriate cables that match the device's power interface.
• The above steps use the Output2 interface as an example. Select the appropriate power output interface of the RAK9105U based on the device’s actual input voltage range. For details, refer to - Output Interfaces.

RAK Battery Plus Data Monitoring and Power Control Application

In the application of the RAK Battery Plus integrating the RAK9105U, it not only monitors the battery's operational status but also enables remote power control for the gateway or other devices connected to the RAK9105U's power output interface.
