PowerBox Systems Digiswitch V2 Instruction Manual page 8

Notes on regulator performance:
The maximum current which the PowerBox DigiSwitch V2 can supply varies ac-
cording to external factors such as battery type and the selected output voltage,
and it is also significantly affected by cooling efficiency. Ideally the battery backer
would be installed on the outside of the model, or inside in such a position that at
least some airflow is present for cooling. In particular when the DigiSwitch V2 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: six small wing servos draw less current
than four 30 kg types.
At the 7.6 V setting the backer does not have to work hard to regulate the voltage
and disperse energy. This increases the performance of the PowerBox DigiSwitch
V2 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 DigiSwitch is already lower.
If you are not sure whether the PowerBox DigiSwitch V2 has sufficient capacity for
the requirements of your system, move all the servos continuously - with the model
on the ground – for about thirty seconds. If the DigiSwitch V2 becomes hot to the
touch (more than 60°C), first check that the servos, pushrods and linkages are in
good order. If you find no problems, then you should use the PowerBox Sensor
instead, as it is better suited to heavy-duty work.
