Receiver Installation
And Power System Requirements
The Spektrum AR12120 PowerSafe™ receiver offers 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.), the AR12120 receiver can
provide peak current of up to 50 amps and offers true dual battery redundancy
and a fail-on soft switch for the ultimate in reliability. By locating up to four
remote receivers throughout the aircraft, the RF link can be optimized in even the
most demanding aircraft installations that have signifi cant conductive materials
like carbon, stainless steel bypass tubes, tuned exhausts, etc. For models high
in carbon fi ber content, the SPM9646 DSMX Carbon Fiber Remote Receiver is
compatible with the AR12120.
Applications
• Giant-scale aircraft
• Jets with multiple high-current draw servos
• Scale aircraft with multiple high-current draw servos and accessories (e.g. lights,
ESCs, air valves, etc.)
• Scale helicopters
Features
• True dual battery redundancy—each battery is isolated so if one fails/shorts the
other takes over.
• Utilizes up to four remote receivers for the ultimate RF link in even the most
demanding applications.
• Up to 35 amps continuous and 50 amps peak current handling capability
• Fail-on soft switch in case the switch is damaged
• Two types of failsafe—SmartSafe (throttle only) and preset failsafe (all servos)
• QuickConnect™ technology—if a power interruption (brownout) occurs, the
system
reconnects in less than 1/2 second
• Flight Log compatible
• Heavy 16AWG dual battery leads with pre-wired E-fl ite
® EC3 ™ connectors
• Compatible with all Spektrum ™ and JR ® full range radio and module systems
• 2048 resolution
• X-Plus
™ compatible
IMPORTANT: The AR12120 main unit is not a typical receiver. The main unit is a
power distribution center that provides up to 35 amps of continuous and 50 amps
of peak current to power your system. Through extensive testing, our engineers
have discovered that mounting the receiver at the end of the servo and battery
leads in sophisticated aircraft (an aircraft with many high-current draw servos
and/or conductive materials) is not the optimum location to provide the clearest
RF signal. Because of this, the AR12120 PowerSafe receiver utilizes up to four
(minimum 3) remotely mounted receivers that can be placed in optimal areas of
your aircraft to provide the best possible RF link in the most demanding condi-
tions.
