Spektrum AR20400T 2.4Ghz 20ch PowerSafe Telemetry Receiver Set

The Spektrum™ AR20400T is the ultimate solution for powering high-current draw radio systems. In aircraft with multiple high-current draw servos (e.g. giant-scale aircraft, jets, etc.), PowerSafe redundancy expertly manages power between both connected receiver batteries with true dual battery redundancy. Each battery is isolated and if one fails/shorts the other seamlessly takes over.

The PowerSafe receivers feature dual battery capacity monitoring through telemetry when used with Spektrum AirWare™ transmitters. Activate the Auto Config function on the telemetry page in your transmitter to display the capacity consumed by the receiver. The capacity used is stored flight to flight and adds until reset. The capacity can be automatically reset when the battery is charged, allowing easy battery capacity monitoring.

When a micro SD card is inserted into the receiver, during operation, flight information will be logged onto a file on the card including flight log data, battery status and other telemetry data stored over time. If not deleted, older data logs recorded will be deleted, keeping the most recent logs. This can be a handy tool to review flight data over time which can be helpful for diagnosis of performance.

You can configure the AR20400T receiver wirelessly, directly from any compatible Spektrum™ transmitter, through the Forward Programming menu. No separate computer or mobile device is needed for setup and adjustments.

A user-friendly Micro USB port is built into the receiver for easy access to firmware updates via the Spektrum PC Programmer Application.

The Spektrum™ AR20400T receiver features an integrated barometer (built-in pressure sensor) to provide altitude and vario telemetry data without the need to purchase additional sensor modules.

The Status LED will give information about the status of the receiver and give warning codes if there is an issue or condition detected: Differentiate codes/modes by flashing count.

• White Blinking/Breathing - Initializing, not ready to fly
• Red - Failure, failure where you can't fly. Check power or RF.
• Two blinks - 3S Power Detected/Protection engaged
• One blink - No remote detected in port A or not enough remotes detected, need at least 2 remotes connected and one must be in port A.
• Solid Blue - Ready (with recording). Ready to fly recording with SD
• Solid Green - Ready (without recording). Ready to fly, not recording to an SD card.

In addition to the integrated telemetry sensors, the AR20400T supports an expansive list of Spektrum telemetry sensors and 3rd party telemetry accessories. Easily add powerful telemetry data tools to your model such as GPS, Airspeed Sensors, Engine RPM and Turbine ECU telemetry from supported jet turbine controllers.
