Pegasus Ultimate Powerbox V2 for optimal power management at the telescope

Pegasus Ultimate Powerbox V2

The Ultimate Powerbox v2 (UPBv2 in short) is the successor of PegasusAstro´s renowned Ultimate Powerbox. You asked for more features, they kept their promise:

A USB 3.1 Hub has been added - you can switch on/off each USB port ?, more power outputs, more dew heaters, ? new stepper controller that can drive any stepper motor in the astronomy market as well as an expansion port for future PegasusAstro devices that will communicate with the UPBv2 Controller!

If you are tired of carrying multiple power packs and dealing with a mess of power and data cables, the Ultimate Powerbox is the absolute solution. The idea is one enclosure that makes available a sufficient number of amperes. No cables disturb the movements of the mount and the instrument, only the general power cord and one USB data cord comes to the Ultimate Powerbox from which branch off the other cables powering all devices.

Solid Input Socket
A large and solid DC input socket ensures that power cable is always secured in place. Socket is selected to provide all the power you need without voltage drops.

More than 20 A of total power
The Controller has been designed to support up to 20 A of total current.

Please notice that Ultimate Powerbox v2 is not a powerbank. It requires an external power source (battery or PSU) to receive its power.

4x 12 V DC Power outlets for your equipment
Four powerful smart MOSFET transistors provide ?electric juice? to your precious equipment. Sophisticated short circuit and overload per port protections cut the power and report the incident into our software. Every MOSFET is capable to provide up to 7 A of current.

Metal & good quality output sockets ensure that will provide all the juice you need and can secure in place your extension power cables.

Built-in Power Sensors
A precise voltmeter and an ampmeter (can stand up to 30 A) measure and display in real time your power input. If the input is more than 14.5 V the power is instantly cut off to protect your equipment.

Individual Current Meter per 12 V port and dew heater channel
Every 12 V output and every dew heater channel has an internal and independent current meter. You can view every port power consumption in the software.

Stand Alone Software
Pegasus Astro´s modern standalone software has a neat dark skin! Control all Ultimate Powerbox v2 features from this software. Receive metrics, View and zoom into graphs, name your outputs, tune every setting of your Ultimate Powerbox v2 quickly and easily.

Industrial 6 port powered USB3.1 SuperSpeed Hub
An industrial USB3.1 port chip ensures that this USB hub will work flawlessly from temperatures of -40 °C to +80 °C.

A neat feature is that each USB port can be switched ON/OFF individually by the software. A device was stuck and you had to replug the socket in the middle of a cold night? No problem! Just locate the port, click the ON /OFF switch in our software and you recycle the USB port. Simple as that!

At the back of the UPBv2 you can locate:
  • 4 x USB 3.1 Super Speed ports
  • 2 x USB 2 High Speed ports


Each USB port provides up to 2.5 Amps. All USB ports include an electronic short circuit and overload electronic protection.

Embedded Stepper Motor Controller
A stepper motor controller will precisely move your focuser. The controller drives a Pegasus Motor or any other stepper motor in the market (Unipolar or Bipolar) e.g. Rigel, Robofocus, Moonlight Motor.

Note: make sure you have the correct cable for your motor. Every manufacturer uses its own pinout. Contact us if you have any question for the type of your motor.

Supported Stepper Motors
  • Pegasus MFK: Requires RJ45 to RJ45 common straight network cable (link to pinout)
  • Robofocus: Requires cable RJ45 to DB9 (link to pinout)
  • Moonlite: Requires cable RJ45 to DB9 (link to pinout)
  • Lakeside: Requires cable RJ45 to DB9 (link to pinout)
  • Starlight HSM 20,30,35: Required custom pinout RJ45 to RJ45 cable (link to pinout)
  • Starlight MSM 20,30,35: Requires RJ45 to RJ12 custom network cable (link to pinout)
  • Rigel nStep: Requires RJ45 to RJ12 custom network cable (link to pinout)
  • Starizona Microtouch: Requires RJ45 to RJ12 custom network cable (link to pinout)


Backlash compensation is already implemented in the firmware and can be enabled, tuned and disabled from the software. A fully ASCOM6 focuser driver is already available.

Three channel duty cycle PWM outputs

Three pulse width modulation (PWM) outlets are capable to provide power to your "thirsty" dew heaters, flatpanels or telescope fans. Eliminate the moisture that is fuzzing your equipment and destroying your clear nights. These outlets can be remotely tuned from your laptop using the supplied software.

A Variable & Voltage Regulated Output
One regulated output that can provide up to 3 Amps of current is available. You can tune the output from 3 Volt to 12 Volt and save this setting in controller?s memory. Every time UPBv2 boots the port will be tuned to the stored voltage setting.

Always ON - 12 V Output
One unregulated 12 V output can provide up to 8 Amps. So, in addition with the Smart 4 x 12 V outputs, you have one more to connect additional equipment. This 12 V output port stays always ON!

Expansion Port (EXT)
An RJ12 expansion port is available for future devices. Expansion Port allows the connectivity of current and future Pegasus Astro Products. Plugged devices can be controlled from UPB software (ASCOM /INDI / Standalone).

Auto Adjustment of PWM (Dew Outputs)
Firmware can auto adjust the PWM Outputs by consulting the environmental sensor dew point reading. Just click "Auto" and leave to Ultimate Powerbox v2 decide if it is time to switch on your dew heaters.

Notice: you can select which dew heater output is controlled by the "Auto Dew" function.

ASCOM 6.4 fully supported
Ultimate powerbox fully supports ASCOM6. In combination with PegasusAstro´s main program which acts as a server you can use the latest ASCOM 6.4 supplied drivers to:
? Control stepper motor (ASCOM Focuser)
? Pass environmental settings to supported software (e.g. Sequence Generator Pro / MaximDL) (ASCOM ObservingConditions)
? Switch ON or OFF all 12 V outputs (ASCOM Switches)

INDI support
Ultimate Powerbox v2 is fully supported by INDIGO and INDI:
  • Indigo: http://www.indigo-astronomy.org
  • Indilib: https://indilib.org/devices/auxiliary/pegasus-ultimate-power-box.html


Fully compatible with StellarMate.

External brackets support
PegasusAstro provides an optional pair of brackets to grab the Ultimate Powerbox device onto a Losmandy 3? or Vixen plate. Both brackets can be screwed on the side of the controller and grab on your telescope.

LED Indications for power and failure states
LED can blink in patterns to warn you regarding important power issues (e.g. over or under voltage). Moreover light can be turned off using the software. Pegasus´s LED is very dim, but in case you don?t like the brightness you can switch it off via the software.

Power Cables are included in the package
Four (4) power cables of DC 2.1 mm to 2.1 mm male (1 m) are included in the package. Cables are thick enough to support up to 6 Amps of current.

External Environmental Sensor
External temperature & relative humidity sensor is included in the package. Know exactly the environment conditions of your location. Temperature, humidity and dew point measurements are displayed in the software.

Zoomable and Exportable Graphs for Power and Environment values
Software logs all voltage, current, temperature and relative humidity readings. All these plots are zoomable and easily exportable in PNG image & CSV text format. Keep a full record of your night conditions.

Timer to shutdown outputs
Choose the time and start timer to shutdown output ports when you schedule it.

Memory persistent outputs on startup

You can easily define which output should turn ON during startup. The setting is stored in system´s EEPROM memory. A neat feature in case of a power failure.

USB3.1 Connectivity
Controller is always attached in the USB hub (7th USB port). No extra cable needed. Just connect the USB hub to your laptop and you are ready to go.

Reverse Polarity Protection:

Ultimate Powerbox has been design with a reverse voltage polarity protection. It will definitely save your night if you accidentally connect the main power supply in reverse polarity!

Watchdog
A hardware watchdog resets the device if for any reason there is no response from the controller for two seconds. A neat feature in the unlikely event of a controller freeze - when you have a remote observatory and you need to be certain that everything works as expected.

Upgradable Firmware
Device is easily firmware upgradable to support future features and bug fixes.
