Product Usage Instructions

1. Ensure the battery input voltage is within the range of DC7.4-26V.
2. If using a single battery, plug it into BAT1.
3. If using dual batteries, choose between Balance Mode or Backup Mode:
   • Balance Mode: When both batteries are plugged in, the Power Redundancy function is automatically activated. The system will use the battery with the higher voltage to balance power consumption across both batteries. If the voltage of both batteries is the same, both batteries will supply power simultaneously.
   • Backup Mode: When the primary battery is consumed to the preset voltage limit, the system will allow the backup battery to join and balance power consumption across both batteries. In this mode, you can set the consumption limit of voltage for the primary battery.
4. To switch between voltage modes, press the button on the Power Switch. There are four modes available: 5.0V, 6.0V, 7.4V, and 8.4V.
5. Ensure that the output power of both batteries is not lower than the power needed for the connected devices to avoid insufficient power supply.
6. If desired, connect an external switch (e.g., NFC Switch) to enable flexible options for switching the power on/off without the need to plug/unplug the battery connections.
7. For advanced configuration and scripting options, please download the Lua scripts from the product page and follow the provided instructions for setup.

Introduction

• The Power Switch is a power control system that offers a safe and flexible powering solution for controlling power in your RC model builds.
• The Power Switch provides the user with a safe and efficient way to power the system with your power sources connected via a pair of standard XT30 connections. Its dual-power consumption system is designed to operate either in Balance or Backup mode. In Balance Mode (default), it consumes the power line from either power source depending on which has the higher voltage. When switching to the Backup Mode, the system consumes the power line with the priority that the user selected under the set voltage range.
• A built-in high-quality BEC unit provides the powering solution, supporting dual input and dual output ports with XT30 connections. The BEC’s design allows the XT30 output ports to be configured to supply 5V to 8.4V either by Lua script (on ETHOS), or alternatively by using the Press button on the CNC aluminum case to quickly switch between the different preset voltages. The power switch is capable of working continuously under high current loads, and benefits from the high-quality machined heat-sink dissipation design.
• The power switch function supports multiple types of external switches (e.g. NFC switch, etc.) that enable flexible options on how the power can be switched on/off without the need to plug/unplug the battery connections.

ID Set Up

Each type of FrSky device has its unique Physical ID (Phy ID). When the same type of telemetry comes from a different device, the Application ID (App ID) should be set to different.

• Note: All S.Port/FBUS capable device can daisy chain with each other through via S.Port/FBUS.
• Note:

1. Please move to the [DOWNLOAD] section from the product page to download the functional Lua scripts (Place the decompressed folder in the root directory of the [Script] folder on the memory card to use.)
2. Connect the S.Port/FBUS capable receiver by the S.Port port of Power Switch, and run the [Power Switch] Lua script (in System menu page) after binding the receiver (in FBUS mode) to the radio system.

Dual Power Redundancy

• [Power Switch] → [Battery Mode]

  • Balance Mode
    When the dual batteries are plugged into the device the Power Redundancy function is automatically activated. The system is designed to use the battery line from the higher voltage allowing the balancing of power consumption across both batteries，When the voltage of the two batteries is the same, both batteries supply power simultaneously.

  • Backup Mode
    When the primary battery is consumed to the limitation of the preset voltage, the system will allow the backup battery to join and enter into the balancing of power consumption across both batteries. In this
    mode, the consumption limit of voltage can be set for the primary battery.

• Select the battery consumption mode.

• [Power Switch] → [Switch Thro] Note:

  1. Please ensure the battery is plugged into BAT1 while using the single battery.
  2. Please ensure that both battery’s output power is not lower than the power needed for the connected devices, otherwise there will be insufficient power supply for the devices.
