FrSky Power Switch Dual-Input BEC Power Control System – FSK-03071609

FrSky Power Switch Dual-Input BEC Power Control System The FrSky Power Switch provides a safe, efficient, and flexible power-control solution for RC model builds. It combines dual battery inputs, configurable dual BEC outputs, and support for multiple external switch options in a durable CNC-machined aluminum housing. Two standard XT30 battery inputs allow the Power Switch to operate in either Balance or Backup mode. In Balance Mode, the system automatically draws power from the source with the higher voltage. In Backup Mode, the user can select the preferred primary power source and operating voltage range. The integrated high-current BEC provides two XT30 output connections with selectable output voltages of 5.0V, 6.0V, 7.4V, or 8.4V. Output voltage can be configured through a Lua script when using FrSky ETHOS or changed directly using the button on the CNC aluminum case. The finned aluminum housing provides efficient heat dissipation and allows the Power Switch to operate continuously under high-current loads. Support for optional external switches, including NFC switches, provides convenient system power control without repeatedly connecting and disconnecting the batteries.
