2PowerBox-Systems − World Leaders in RC Power Supply Systems
The PowerBox Evo is an ultra-compact dual power supply featuring 7 channels,
regulated output voltage and telemetry. The 7 inputs are assigned to 12 outputs,
allowing two servos to be controlled in parallel on each of 3 channels, without re-
quiring additional Y-leads. All servo outputs have integral signal amplication and
are protected against servo feedback currents.
The PowerBox MicroSwitch included in the set is not subject to wear, and operates
both electronic switches reliably. It is also used to set the output voltage and the
battery type.
By default the two high-performance voltage regulators deliver 6.0V, but that value
can easily be changed to 7.4V, 7.8V or no regulation at all using the PowerBox
MicroSwitch. The machined aluminium heat-sink ensures a high continuous load
capacity.
The PowerBox Evo supports all current telemetry systems: PowerBox, Jeti, Futaba,
Multiplex, Graupner, Spektrum and JR, which means that the voltage of both batte-
ries can be monitored conveniently from the transmitter. It is also possible to read
off the state of charge of the batteries at any time using the two tri-colour LEDs.

1. INSTALLATION, CONNECTIONS
a) Mounting
The Evo should be attached to a robust sub-structure using the four screws, rubber
grommets and brass sleeves supplied in the set; the switch should be mounted in
the fuselage side. We recommend reinforcing the switch aperture on the inside of
the fuselage with a layer of wood to protect the unit from severe vibration; this is
particularly important in models with a GRP fuselage. An external switch is often
undesirable on a scale model, and for such applications we offer the PowerBox
MicroMag as an alternative. However, please note that - unless you are using a
PowerBox or Jeti system - the PowerBox MicroSwitch is required for programming
the battery type and the output voltage.
The PowerBox MicroSwitch is connected to the socket marked Switch on the side
of the PowerBox Evo. In models where severe vibration is likely to occur, we recom-
mend that the ribbon cable should be secured at a minimum of one additional point

to avoid the plug working loose. If the ribbon cable were to fall out, it would have
no effect on the backer’s switched state, but would make it impossible to switch
the system off.
b) Receiver
Start by connecting all the servos to the appropriate channels; the assignment is
entirely up to you. For example: input 4 corresponds to output 4, but whether you
connect the aileron servo or the throttle servo is a matter of your choice.
Channels 3 – 4 – 5 each have two outputs, allowing you to connect two servos
without a Y-lead. But please note: the PowerBox Evo does not feature servo
matching, so the servos must be adjusted mechanically for equal travel if both are
connected to the same control surface.
Connect the receiver using the seven patch leads supplied in the set. Power is fed
to the receiver through these leads.
Connect the telemetry patch lead to the Telemetry input on your receiver as follows:
PowerBox: P²-BUS
Jeti: EX-BUS
Futaba: S.BUS2
Spektrum: SRXL2
Graupner: T
Multiplex: Sensor
JR: Sens
The telemetry system is detected automatically, so you do not have to make any
further adjustments.

c) Batteries
The nal step is to connect the batteries to the MPX sockets on the backer. We
recommend that you use our PowerPacks 2.5 x 2.
Caution: If you intend to use other makes of battery, or packs you have as-
sembled yourself, please take great care to maintain correct polarity - better to
check twice! Connecting a battery just once with reverse polarity will always
destroy the backer’s regulators. The unit does not feature polarity protection, in
order to minimise power losses. The + indicator is engraved on the heat-sink.
2. SWITCHING ON
The push-button switch operates in the same way as all PowerBox systems: hold
the button pressed in until the LED starts to ash green at a high rate. Briey relea-
se the button, then press it again. The LED now lights up a constant green, indica-
ting that the unit is switched on.
Repeat the procedure to switch off.
If you are using a PowerBox MicroMag, hold the magnet against the switch until
the PowerBox Evo turns itself on. The LED lights up blue as soon as a magnet is
detected. The LED turns red to indicate the end of the switching process; after this
the LED glows green to indicate that it is switched on.

3. SETTING THE BATTERY TYPE
It is important to set the battery type, otherwise the LED battery indicator cannot
work properly. This is the procedure: rst switch the PowerBox on, then hold the
button pressed in again.
After about ve seconds the LEDs go out, and a sequence of different colours com-
mences, each colour corresponding to one battery type. Release the button when
the LEDs light up in the colour corresponding to your battery type. Both LEDs ash
white to conrm the setting, and the battery type is then stored.
LiPo LiIon LiFe NiMh
Information on the LED display: the display does not correspond to battery voltage
in a linear manner. We have measured different battery types in current use to pro-
duce an average discharge curve. This discharge curve is used in order to provide
a percentage display.
The LED display corresponds to the battery capacity in the following way:
PowerBox and Jeti users can also carry out this adjustment directly at the trans-
mitter. You will nd the setting in the EVO Telemetry menu on PowerBox transmit-
ters, and in the JetiBox application with a Jeti system.
80 – 100 % 60 – 80 % 40 – 60 % 20 – 40 % 0 – 20 %

4. SETTING THE OUTPUT VOLTAGE
The PowerBox Evo can be set to four different output voltages: on the one hand to
6.0V for conventional servos, on the other to 7.4V, 7.8V or completely unregulated
for HV servos.
If you intend using the last named setting, please ensure that all components
connected to the system are safe for use on high voltage.
The advantage of regulating the voltage at 7.4V or 7.8V, instead of simply allowing
the full battery voltage through, is that it reduces the high battery voltage which is
present immediately after charging. A constant voltage is then fed to the system
right from the outset, ensuring consistent servo speed and power over a long pe-
riod.
To change the output voltage, connect one of the batteries whilst holding the but-
ton pressed in. The LED will initially light up green, then turn orange after three
seconds, then violet after six seconds, and nally red after a further nine seconds.
The output voltage is set in accordance with the LED colour when you release the
button. The output voltage assignment is as follows:
6.0 V 7.4 V 7.8 V non-regulated
Finally the LED ashes white to conrm that the setup procedure is complete. Dis-
connect the battery, and repeat the procedure with the second battery socket.
PowerBox and Jeti users can also change this setting directly at the transmitter.
You will nd the setting in the EVO Telemetry menu on PowerBox transmitters, and
in the JetiBox application with a Jeti system.
