Notes on regulator performance:
The maximum current which the PowerBox Sensor V3 can supply varies accor-
ding to external factors such as battery type and the selected output voltage, and it
is also signicantly affected by cooling efciency. Ideally the battery backer would
be installed on the outside of the model, or inside in such a position that at least
some airow is present for cooling. In particular when the Sensor V3 is used with
LiPo or LiIon cells, and the output voltage is set to 6.0 V, the number of servos
connected to the system should not be excessive. At the same time please bear in
mind that not all servos are equal: eight small wing servos draw less current than
ve 30 kg types.
At the 7.8 V setting the backer does not have to work hard to regulate the voltage
and disperse energy, and this increases the performance of the PowerBox Sensor
V3 substantially. The same applies to the 6.0 V output voltage setting if LiFePo or
NiMH batteries are used, since the input voltage at the Sensor V3 is already lower.
If you are not sure whether the PowerBox Sensor V3 has sufcient capacity for the
requirements of your system, move all the servos continuously - with the model on
the ground – for about thirty seconds. If the Sensor V3 becomes hot to the touch
(more than 60°C), rst check that the servos, pushrods and linkages are in good
order. If you nd no problems, then you should use the PowerBox Source instead,
as it is better suited to heavy-duty work.
