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.

Setup Guide - Dual Power Redundancy
[Power Switch] → [Battery Mode] Select the battery consumption mode.
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.
[Power Switch] → [Switch Thro]
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.
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.
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.
