PowerBox Systems EVOLUTION Instruction Manual page 7

In 7.4 Volt mode the dissipated power is lower, and this means that the power of
your PowerBox Evolution is about 30% higher.
By default both voltage regulators are set to 5.9 V. If you wish to use high-voltage
servos (HV servos, designed for up to 8.4 V), the PowerBox Evolution allows
you to operate the servos on a regulated voltage of 7.4 V instead of 5.9 V. The
advantage of a regulated 7.4 V voltage compared with an 'open' 8.4 V battery
is that the regulated voltage causes all servos to work constantly at the same
speed and generate the same torque. This is an important advantage which is
particularly appreciated by all our competition pilots, as it makes all manoeuvres
more predictable and easier to fly.
A further advantage of a regulated 7.4 V servo voltage is a longer effective life for
your servos, as it eliminates the voltage peaks which occur when the batteries
are freshly charged.
Setting the servo voltage:
The procedure for switching the unit to 7.4 Volts is quick and simple, and only
needs to be carried out once. The setting is stored permanently, but can also be
changed again at any time. The change must be carried out for each of the two
voltage regulators, as the PowerBox Evolution features two regulators which
work independently of each other.
