INTRO
Thank you for purchasing our Pegasus Astro –Pocket Powerbox Advance. Pocket Powerbox Advance (in short
PPBADV) is suitable for the “grab and go” astronomer / photographer. Device can provide up to 12 Amps of electric
current, has four 12V outputs, a quad port USB3 Hub, two dew heater channels, a variable voltage output and an
external environmental sensor to constantly monitor relative humidity and ambient temperature. Controller can
adjust the dew heaters consulting the sensor temperature / humidity values and calculating the dew point of the
environment.
CONTROLLER CARE
•Controller is protected from moisture but it is not waterproof and it should be kept clean and dry.
•Excessive moisture for long periods of time can damage electronics and connectors.
•Do not allow solvents or chemicals to come into contact with the device.
•Store controller indoor in a dry room when not in use for long time.
•Do not touch the internal components as they may get hot when in use.

What is
inside the box
Pocket Powerbox Advance
1 x DC Cable (2.1mm) to Cigarette Lighter
(8A fused)
4 x Power Cables (1 meter)
1 x USB2 Cable Type B (1.8m)
1 x Environmental Sensor (RJ12)
OPERATING INSTRUCTIONS
1. Plug the external environmental sensor into EXT port.
2. Plug the USB3 cable to the device and to your computer.
3. Plug the power supply (battery or power pack) into the “12V DC IN” socket. We strongly advise to use our
certified power supply that can provide DC 12V and 10 Amps.
4. Device will boot after three seconds and the LED will turn solid blue. This means that firmware was loaded
successfully and the controller is now fully operational.
5. Default settings provide DC pass through voltage to all four outputs. Dew Heater outputs are configured to
auto-dew by default.
6. Download USB drivers, standalone software or ASCOM drivers from pegasusastro.com/support in order to
connect to the device.

POWER INPUT
Controller can accept voltage ranges from DC 12V –14.5V *.
>> We strongly recommend you use our certified “Pegasus Astro 12V power supply” <<
A 13.8V lead (or calcium/lead) battery is also recommended. Please use a power supply that can provide at least 6
Amps of current. For your observatory needs you might need up to 10 Amps of current.
Under no circumstance exceed DC 15.0V input as you will cause a severe damage
controller electronic board
Unit has been designed with reverse polarity protection. If you accidentally reverse the power source polarity, the
unit will cut the power. The controller is fitted with a 2.1mm DC power connection which powers on the unit.
Insert the 2.1mm plug on the DC power cable. Controller will initialize and the status LED will turn solid blue after 4
seconds. (The 4 seconds wait time duration is on purpose for a new firmware upload process)
* Above 14.5V the Pocket Powerbox will shut down all 12V output ports to save your precious equipment from overvoltage.
DATA CONNECTIVITY
A USB3 Type B port at the side of the unit accepts the USB cable for PC connection. A 1.8m USB3 type B cable is
supplied in the package.
USB3 HUB
A powered USB3 Hub at the back of the device provides 4 x USB3 SuperSpeed Ports.
Hub supports Hi-Speed (HS), Full Speed (FS) and Low Speed (LS). The new SuperSpeed hubs operate in parallel with
the USB 2.0 controller, so 5 Gbps SuperSpeed data transfers are not affected by slower USB 2.0 traffic.
Please note that only 3 out of 4 USB Ports are compatible to USB2 devices (as shown below).

12V POWER OUTPUTS
Pocket Powerbox device has:
Four (4) 12V DC unregulated outputs. All outputs are driven by a single Smart Mosfet, capable to deliver up
to 10 Amps of current (in total). This mosfet incorporates a broad range of smart features like diagnose and
protection. The 12V Channel can be switched ON/OFF via software.
Each 12V power output has the following specification:
Voltage type
Port
12V-13.8V DC unregulated
2.1mm DC Power Jack / Center Positive
DEW HEATER OUTPUTS
Device has two (2) channel dew heater outputs. Like power outputs, each dew heater output includes a Smart
Mosfet type, capable to deliver up to 5 Amps of power per channel.
Auto-Dew: A smart function exists in the controller’s firmware: The controller consults the environmental readings
of the dew point and automatically adjust power of the Dew Heaters. This functionality can be switched on / off
from the software and the setting is stored in controller’s memory.
Note 1: Auto Dew functionality is turned on by default
Note 2: Dew heater outputs are also suitable to light a flat panel or turn your telescope’s fans.
Voltage type
Port
12-13.8V DC, PWM - Duty Cycle %

BUILT IN POWER SENSORS
oMain output channel (4 x 12V) incorporates a current meter. A Smart Mosfet is capable to diagnose the
power consumption of these 4 ports and provide protection against overload, over temperature and short
circuit.
oEach Dew Channel incorporates a current meter ports and provide protection against overload, over
temperature and short circuit.
oA DC voltmeter exists after controller’s power input. (Measures 5 –15 Volts).
oA current meter exists after controller’s power input. (Measures 0 –20 Amps).
ADJUSTSTABLE OUTPUT
A 2.1mm output provide 3-12V and 3A of current (max). This regulated output is configured to 3V by default.
You can adjust the voltage of this output via the supplied software to 3, 5, 8, 9 or 12 Volt levels. Setting is stored in
controller’s memory and is automatically retrieved during boot.

You can use a wide range of our Battery Couplers (NIKON / Canon / Fuji / Sony) to provide constant power to your
DSLR / Mirrorless camera. If you use this output for battery couplers you must set it to 8 Volts.
Voltage type
Port
3-12V DC regulated
2.1mm DC Power Jack / Center Positive
Adjustable Output can turn ON/OFF via software
ENVIRONMENTAL SENSOR
The stock probe is an external temperature / humidity sensor which is attached to the controller. It comes with
length of 50cm cable. Probe measures:
•0 to 100% humidity readings with 2-5% accuracy
•-40 to 80°C temperature readings ±0.5°C accuracy
The unit automatically detects the presence of the probe and polls for temperature readings every 15 seconds.
A RJ12 socket connects the temperature/humidity sensor with the Pocket Powerbox Advance controller.
RESET WATCHDOG
A watchdog resets the device if for any reason there is no response from the controller after two (2) seconds. A neat
feature in the unlikely event of a microcontroller freeze –when have a remote observatory and you need to be sure
that everything works as expected.

RECOMMENDATION.
•It is wise to select and use good quality and short length USB cables.
•Do the same for power cables. Long and thin power cables will have an effect of voltage drops. This can
cause issues to your camera (CCD or CMOS) image quality or mount tracking.
•Make sure you use a good quality DC input socket with a thick power cable (1.5mm each pole). Verify there
are no gaps that can cause power disconnect
•Pay extra attention of you are using a “step up voltage converter” in the DC input. You need at least 6 Amps
to power all of your devices. (We don’t recommend step up converters –buy a good battery or a check our
certified 12V/10A power supply).

FREQUENTLY ASKED QUESTIONS
Question
Answer
What kind of power supply do I need?
We strongly suggest to use our certified 12V/10A
power supply. Cheap units might lead to voltage drops
on high load and ripple effect. This will cause issues
and artifacts to your precious CCD / CMOS Camera.
What type of cable do I need to use for input?
If you are going to make a custom input cable notice
that you need at least a AWG 17 cable. Make also sure
that you do not exceed 2meters (6feet) to reduce
voltage drops.
I would like to use the Pocket Powerbox to my remote
observatory. What if the device freezes for some
reason?
We have good news for you. The device has a
hardware watchdog and resets itself if the
microcontroller is not responsive after 2 seconds
My observatory is in a very cold place. Is there any
issue with the electronics of the device?
Electronic components were selected to support
temperature ranges from -40 to +80 °C.
What if I accidentally reverse polarity?
Pocket Powerbox has an input reverse polarity
protection. Device will not power on and of course will
not allow any voltage to flow to outputs.
Can I upgrade the firmware?
Of course, device has been designed to support
firmware upgrade for future features or bug fixes.
