The Spektrum™ AR20400T PowerSafe™ receiver is a feature-packed 20-channel receiver with integrated full-range telemetry. Spektrum PowerSafe receivers are designed for models with numerous servos and accessories that have high power requirements, as is often the case with large models and jets. They feature a robust power bus designed for high currents, as well as two battery inputs with 13AWG cable and IC3 Connectors™ for use with larger battery packs. This makes it possible to power high current systems directly from the receiver without the need for a separate power supply.
If your DSMX®/DSM2 transmitter® supports a frame rate of 11ms, then the AR20400T will give you lightning fast control response, essential for the extreme demands of aggressive 3D flight, aerobatic models and jets. Each receiver comes with 4 SRXL2 satellite receivers that take full advantage of Spektrum MultiLink Technology™. This patented technology eliminates fading due to reflected signals and antenna blind spots, a problem that can affect all 2.4 GHz systems. As a result, it helps ensure a solid connection between you and your model aircraft.
As an added safety feature, Spektrum has equipped the AR20400T receiver with a proprietary soft switch. If the switch fails for any reason, power to the system is not interrupted because servo current is routed past the switch.
A groundbreaking feature of the AR20400T PowerSafe receiver is the receiver's integrated battery sensing system. This provides pilots with additional information about the load and power consumption of the servos, retracts, lights, etc. from each pack.
The receiver has built-in connectors for telemetry modules such as tachometer, drive battery voltage and temperature, as well as an X-Bus connector for additional telemetry options.
Features:
- Patented PowerSafe™ dual power supply via two battery inputs with 13AWG wire and IC3 connectors. Perfect for power-hungry model aircraft and high current servos up to 35A (50A short duration).
- Forward programming allows easy adjustments to failsafe settings, servo frame rates and more
- Micro USB port for easy product registration and firmware updates
- 12V capable for use with 12-volt servos (must be enabled via forward programming)
- Built-in battery capacity monitor reports battery capacity used during flight and can be automatically reset when fully charged batteries are plugged in
- Integrated black box telemetry log automatically saves all telemetry data to a micro SD card (micro SD card not included)
- Integrated status LED provides helpful information during startup and indicates warnings and mode
- SRXL2 connectivity for easy connection to supported devices over a single line
- Instantly ready and compatible with Spektrum Smart controller for telemetry data over a single line without additional modules, connections or cables
- Receiver battery voltage, voltage sensor and flight log data are transmitted without additional sensors
- Full-range telemetry with integrated barometer to transmit altitude and vario telemetry data without additional sensors
- The included soft switch allows the power supply to be routed past the switch. Thus, in the event of a switch failure, the power supply to the system is not interrupted.
- Rubber-mounted mounting tabs and minimalist labeling allow for clean and visually appealing installation
- High-speed frame rate of 11ms
- Four options to initiate the binding process make binding easier than ever before
- Integrated telemetry with built-in ports for speed, battery pack voltage, temperature sensors and X-Bus telemetry sensor expansion
- Optional fourth SRXL2 satellite receiver can be added for additional RF redundancy (sold separately)
- Compatible with all Spektrum DSM2 and DSMX transmitters
- Not compatible with Spektrum AS3000 stabilization module
- Not compatible with the DSM2 AIRMOD JR module (SPMMSJR720)
