1. History of PowerBox Systems voltage-stabilised battery backers
TOC 2002, Las Vegas: this is where the development of the first voltage-stabilised
power supply systems for model aircraft began. In October 2002 Sebastiano
Silvestri took part in the Tournament of Champions at Las Vegas; he was the first
TOC participant to have a type of receiving system power supply installed in his
Katana which had never been seen before. This was the PowerBox 40/24
Professional, developed by us and an extremely successful unit, with “remotely
accessed” channels (i.e. remote >from the receiver), signal amplification, voltage
monitoring and much more besides - it could be summed up as a complete servo /
receiver management system. At that time all the top European pilots were still
flying their models with four-cell or five-cell NC batteries, or the then new NiMH
packs, but in the USA many leading flyers were already using Li-Ion batteries made
by the renowned battery manufacturer DuraLite. It was inevitable that Emory
Donaldson, Manager of Duralite, would be present at the TOC, and he showed
great interest in the type of power supply represented by the PowerBox
Professional. There and then - in Las Vegas - he granted us a contract to develop
a power supply system for DuraLite Li-Ion batteries, which have a voltage curve
similar to the LiPo types now in common use (max. 8.4 Volts). Only five months
later, in April 2003, we were able to present him with a power supply system which
contained a linear voltage regulator - a completely new in-house development - two
electronic switches, double voltage monitor etc.
(registered design DE 203 13 420.6).
This linear voltage stabilisation circuit supplies a constant 5.9 Volts and offers a
particularly high performance; it has been employed unchanged in all our regulated
battery backer systems and switches since 2003. All the companies which produce
competing products have copied this idea, and fitted their battery backers not only
with a regulated voltage circuit, but also the original PowerBox stabilisation circuit.
From the outset we decided on a constant voltage of 5.9 Volts for receivers and
servos, not least because that was the preferred voltage of many competition pilots,
and this voltage value has been adopted as a standard by other manufacturers. For
us and for our customers this is reassuring, and ample evidence of the rightness of
our concept, since good ideas and innovative electronics always find their way to
the front!
2. Product description
The PowerBox 40/16 Evolution is a modern power supply system which contains
all the electronic components which are necessary for modern servos and models.
Basically, all the essential components, ICs and electronic circuits required for a
reliable power supply system are duplicated!
