The Advanced Radio AR Ultra Switch is a lightweight, high-current power-management system designed for almost any RC aircraft. It combines dual battery inputs, active load sharing, two regulated power outputs and automatic telemetry detection into one ready-to-install unit.

Designed to provide additional power-system resilience, the Ultra Switch automatically transfers the full load to the remaining battery if one battery fails or becomes disconnected. This helps keep the radio and onboard electronics operating without requiring manual intervention.

Both power outputs deliver the same selected voltage, with selectable settings of 6.0V, 6.6V, 7.4V or unregulated 8.4V, allowing the system to be matched to a wide range of RC aircraft electronics and servos.

Automatic telemetry discovery removes the need to manually select a telemetry protocol. Where supported, pilots can monitor both battery voltages, current consumption and consumed capacity directly from their transmitter.

The AR Ultra Switch also features dual multicolour battery-status LEDs, a blue power indicator and a deliberate two-button shutdown sequence designed to help prevent accidental power-off during operation.

Designed and made in Australia.

Product Summary

The AR Ultra Switch provides a compact and dependable way to manage dual battery power in an RC aircraft. Its active load-sharing system automatically uses the remaining battery if one power source fails or is disconnected, helping maintain power to the onboard radio system.

With dual power outputs, four selectable output options, automatic telemetry detection and high-current capability, the Ultra Switch is a versatile power-management solution for demanding RC installations.
