Since 2003 there has been a name for dual security in
minimum space: PowerBox Sensor!
The PowerBox Sensor is probably the best-known product in
the PowerBox portfolio. The two voltage regulators allow it to be used for
virtually any application where double security is required in conjunction with
modern battery technology. The unit's small physical size and low weight make
it very simple to install in any small to medium-sized model.
The PowerBox Sensor provides genuine redundancy in the power
supply system, and is in no way inferior to its big brothers in terms of
security, as it features two integral, completely independent regulatory and
switching systems. Other comparable products available commercially boast of
duplication, but this always simply refers to the number of batteries connected
to the system. Our backer is actually fitted with two micro-controllers, two
regulatory circuits, two switch circuits and a dual voltage monitoring circuit.
In order to be able to use modern battery types such as LiPo
and LiFePo, the two integral regulators reduce the battery voltage to 5.9 V,
which is the correct value for 6 V servos. The unit is also a good choice for
capping the voltage of 5S NiMH packs at 5.9 V, as the voltage of these batteries
can be excessive when fully charged. Regulating the voltage extends the useful
life of the servos, and ensures constant servo torque and transit speed -
regardless of the state of charge of the batteries.
Two tri-colour LEDs indicate the state of charge of the
batteries in four stages. The backer also includes a minimum voltage memory
which stores the lowest voltage value which occurs during a flight, enabling
the pilot to monitor his batteries more accurately. After the flight the
minimum value can be read from the LEDs by pressing buttons I and II.
