2 PowerBox-Systems − World Leaders in RC Power Supply Systems
Dear PowerBox customer,
Congratulations on your new PowerBox power supply unit! The PowerBox Mercury
SR2 is your rst choice when you need a small, high-performance power supply unit
with maximum functionality. All the features which are usually the preserve of the
larger power supply units are present in the compact PowerBox Mercury SR2: iGy-
ro, servo matching, unrestricted channel assignment and even a door sequencer: it
really is a complete system!
The PowerBox Mercury SR2 provides 16 freely assignable outputs with servo
matching, i.e. the travel of each channel can be adjusted at ve points. If you y mo-
dels with large control surfaces, in which individual control surfaces are actuated
by two servos, the unique auto-match function can be used to match both servos to
each other accurately in a matter of seconds.
The integral iGyro software requires a sensor unit in the form of an iGyro SAT; with
this it can address and adjust three aileron, three elevator and three rudder func-
tions individually. The Setup Assistant simplies the initial adjustments to the gyro
system, reducing the time required to just a few minutes. The rst time the system
is used, the Assistant gathers basic information regarding wing and tail format and
the vector control system - if present. A complex model matrix then works in the
background, calculating which servo needs to be connected to which output, at
the same time linking the corresponding gyro function. A wide range of additional
Expert settings offers total freedom, enabling you to ne-tune the gyro system to
your particular requirements.
In addition the GPSIII or PBS-TAV (True Airspeed Vario) can also be connected to
the FastTrack input, making it possible to vary gyro gain according to airspeed. All
GPS or TAV information is even available for telemetry at the transmitter!
The PowerBox Mercury SR2 supplies a regulated output voltage which can be set
to 6.0V or 7.8V. The two voltage regulators offer generous capacity thanks to the
machined aluminium heatsink on the top and bottom surfaces, enabling the unit to
cope effortlessly with the current-hungry servos used in 3D machines.
The integral door sequencer is capable of controlling one undercarriage system and
up to three wheel doors. If the Setup Assistant is used, it takes just a few minutes
to learn the end-points of door travel, while three pre-dened modes cover the vast
majority of undercarriage processes. Once initially set up, the timing of the process
can be ne-tuned manually to any values you wish.
