Spektrum RC AR20400T 20-Channel DSMX PowerSafe Telemetry Receiver

The Spektrum RC AR20400T 20-Channel DSMX PowerSafe Telemetry Receiver is a feature-packed receiver with integrated full-range telemetry. PowerSafe receivers are designed for models that numerous servos and accessories that draw excessive amounts of current. These features and functions make it possible to support high-current systems straight through the receiver without the need for a separate power distribution system. Protect your investment using the Spektrum PowerSafe line of receivers.

When combined with a DSMX/DSM2 transmitter capable of 11ms frame rates, this AR20400T will deliver lightning fast input-to-output response. This is perfect for high performance applications such as aggressive 3D, IMAC and Turbine applications. This receiver includes 3 SRXL2 remote receivers that take full advantage of the Spektrum MultiLink technology. Using this will eliminate the reflected signal fading and antenna blind spots that can affect all 2.4GHz systems.

The Spektrum AR10400T 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.

The Spektrum AR10400T receiver features an integrated barometer (built-in pressure sensor) to provide altitude and vario telemetry data without the need to purchase additional sensor modules.

• Patented PowerSafe redundancy system with dual 13 AWG battery leads with IC3 connectors. Perfect for power hungry aircraft and high current servo applications drawing up to 35A (50A max burst)
• Forward programming allows for easy adjustments to failsafe settings, servo frame rate settings and more
• Micro USB port for easy product registration and firmware updates
• 12V capable for use with 12 volt servo applications (must be activated via Forward Programming)
• Integrated battery capacity monitor automatically reports the battery capacity used during flight and can reset automatically when fully charged batteries are installed
• Integrated Black Box telemetry log saves all telemetry data automatically when a Micro SD card is installed (Micro SD card not included)
• Integrated status LED provides helpful information during start up, warnings and mode indicators
• SRXL2 connectivity for easy, one wire connection to supported devices
• Ready to use with Spektrum Smart ESC for one-wire telemetry data without the need of modules, links and wires
• Receiver pack energy & voltage sensor and flight log telemetry data available without the need for additional sensors
• Full range telemetry with integrated barometer to provide altitude and vario telemetry without additional modules
• Included Soft Switch allows servo current to be routed around the switch, so if the switch fails for any reason, power to the system will not be interrupted.
• Rubber grommet hard mounts and minimalistic labeling helps produce the cleanest model setups
• Capable of high-speed 11ms frame rates
• Binding is easier than ever with four options to initiate the bind process
• Integrated telemetry with built-in ports for RPM, flight pack voltage, temperature sensors and X-bus for telemetry sensor expansion
