Dear Customer,
We are very pleased that you have decided to purchase our POWER BOX 40/16.
With this newly developed product you now have a powerful Dual-Power-control
system for your valuabl e model aeroplane. This will allow you to have not only the
extra safety advantage of coupling two on board flight battery-packs. But to also
have permanent control of the momentary voltag e o f each battery-pack.
Furthermore this latest Dual-Power control unit also includes one powerful servoamplifier for each of the four recei ver-channels. This special feature will enable you
to connect several servos to each receiver line out.
Although this new Dual-Powe r-Control unit is extremely easy to handle you will
need to ha ve some knowledge for it’s correct use. This comprehensi ve manual will
therefore help you to quickly familiarise yourself with your new accessory.
However, in order to fully understand the advantages and safety features of this
unit all we ask is that you carefully read this manual right through before you
commence using your new Dual-Power-Control. We sincerely hope you’ll enjoy
the many safety features we have built into your new POWER-BOX 40/16.

1. Function of the Dual-Power control
The POWER BOX 40/16 is a Dual-Power-Control system which besides it’s main
function of being a power control unit – it also displays the momentary voltage of
both of the two connected battery packs by a line of 5 ultra bright LEDs. Therefore
you are always able to check the exact voltage of the two battery packs. This
feature allows you to continually check if there’s enough energy left in either of your
two battery packs for another long thermic-flight.
In addition you can also connect up to four servos covering the four most important
channels of your model -aeroplane to the Dual-Power-Control without causing any
problems. This is because the servo-pulses for each of the four channels connected

are correctly amplified by a powerful precise on board operation al amplifier, which
special feature allows you to use extra long servo extension wires of up to 2:metres
between the servos and the recei ver without causing the servos any problems.
It is necessary to decouple the two battery packs. This is provided by a very
powerful Dual-Schottky-Diode. Here, the two diodes are in one package.
This new type of diode allows only minimal voltage drops. Therefore it is absolutely
safe to use the Dual-Power-Control with battery packs made up of four cells only.
The POWER BOX 40/16 operates with two battery-packs of the same size and
voltage; this then means that both battery-packs get discharged steadily. While
operating it’s always the battery with the highest momentary voltage, which will be
stressed. Therefore both battery-packs must have the same number of cells and
must also be of the same capacity. So it’s important that you only use two identical
capacity battery-packs.
During flying you can use the whole capacity of both battery-packs. When one
battery-pack diminishes to the pre-set level the second one will immediately cut in
to provide the necessary power-supply for the receiver and servos. By using our
two special hea vy -duty switches along with our double cable circuitry we provide
you maximum flight security.
The POWER BOX 40/16 is also equipped with two independent voltage-controllers
in order to check the voltage of both sources of energy. Five coloured LEDs display
the momentary voltage of each battery-pack: 3-Green, 1-Orange and 1-Red LED
displays the momentary voltage situation. You should therefore check the battery
packs before each flight.
In fact we suggest that you mo ve the Transmitter control stick in order to make the
servos move briefly. By this method you will of course put a slight stress the
battery-pack. But as long as the battery display shows the green LEDs lit up then
the capacity of the accu-pack is high enough for further use. However, if the Orange
LED lights, then you must recharge your battery-packs and you should not start for
reasons of safety.
Should the Red LED light up then stop flying immediately! This indicates that both
battery packs must
be recharged fully, the Red LED display means that they have
been discharged to the there lower limit of capacity.
The LED display is non-linear, it is adjusted to the performance of today’s NiCd –
and NiMH – batteries. Therefore you can control your battery-packs safely and
more precisely. W e recommend that you let us check the optimal adjustments of
the on board Voltage-Controller every two years. We cannot of course give you any
information on how long your battery-pack will last because this depends on the
capacity of the battery-pack used as well as the total number of ser vos installed in
your model and the number of command signals given.
