AR12120 PowerSafe User Guide
The Spektrum AR12120 PowerSafe™ 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 PowerSafe 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 throu-
ghout the aircraft, the RF link can be optimized in even the most demanding aircraft
installations that have significant conductive materials like carbon, stainless steel
bypass tubes, tuned exhausts, etc. For models high in carbon fiber 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 and 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
™
• QuickConnect—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-flite
• Compatible with all Spektrum and JR
™
• 2048 resolution
• X Plus compatible
™
Important
The PowerSafe main unit is not a receiver. The PowerSafe' s main unit is a power
distribution center that provides up to 35-amps continuous and 50-amps peak
current to power your system. Through extensive testing our engineers discovered
that mounting the receiver in the typical location in sophisticated aircraft (an air-
craft with many high-current draw servos and/or conductive materials), at the end
of the servo and battery leads, is not the optimum location to provide the clearest
RF signal. The AR12120 PowerSafe uses up to four (a minimum of three are
required) remotely mounted receivers that can be optimally placed in your aircraft
providing the best possible RF link in the most demanding conditions.
