Pegasus Astro Ultimate Powerbox Power Pack

If you are tired of carrying multiple power packs and dealing with a mess of power and data cables, the Pegasus Astro Ultimate Powerbox, a sophisticated power control unit, is the “Ultimate” solution. The idea is an enclosure that makes a sufficient number of amperes available. No cables disturb the movements of the mount and the instrument, only the main power cord and one USB data cord is attached to the Ultimate Powerbox from which branch off the other cables powering all devices.

    4 x 12V 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 7A of current.

    Built in Power Sensors

    A precise voltmeter and an ampmeter (can measure up to 30A) measure and display in real time (200 measurements per second) your power input. If the input is more than 13.8V the power is instantly cut off to protect your equipment.

    Individual Current Meter per 12V port

    Every 12V output has an internal and independent current meter. You can view every port power consumption in the software.

    More than 20A of total power

    Controller has been designed to support up to 20 Amps of total current.

    * Please notice that Ultimate Powerbox is not a powerbank. It requires an external power source (battery or Power Supply Unit, which can be purchased here).

    Stand Alone Software

    The standalone software has a neat dark skin! Control all Ultimate Powerbox features from this software. Receive metrics, View and zoom into graphs, name your outputs, tune every setting of your Ultimate Powerbox quickly and easily.

    Industrial 6 port powered USB2 High speed Hub

    An industrial USB2 port chip ensures that this USB hub will work flawlessly from temperatures of -40°C to +80°C. A nice feature is that USB Hub can be turned ON/OFF by the software. Moreover, USB port No 6 never turns off and supports up to 3A of current. A very handy feature if you have a Compute Stick * and you want to get a 5V input power. All USB ports include a unique short circuit and overload electronic protection.

    If you own an Intel M3/5 PC Stick which has a USB-C socket you will need a USB A -> USB-C “fast charging” cable that can provide 3Amps. Normal USB-C cables have an internal resistor which limits current to 2.2Amps and leads to PC Stick shutdown. 

    Embedded Stepper Motor Controller

    A stepper motor controller will precisely move your focuser. Connect a Pegasus Unipolar Motor or another motor in the market e.g. Rigel, Robofocus, Moonlight Motor. Backlash compensation is already implemented in the firmware and can be enabled, tuned or disabled from the software. A fully ASCOM6 focuser driver is already available.

    Two channel duty cycle PWM outputs

    Two Pulse width modulation (PWM) outlets are capable to provide power to your “thirsty” Dew Heaters. No more moisture fuzzing your equipment and destroying your clear nights. These outlets can be remote controlled from your laptop using the supplied software.

    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 Intelli Powerbox decide if it is time to switch on your dew heaters.

    ASCOM 6 Fully supported

    Ultimate powerbox fully supports ASCOM6. In combination with our main program which acts as a server you can use our latest ASCOM 6.3 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 12V outputs. (ASCOM Switches)
    Ultimate Powerbox ASCOM Environment

    INDI Fully supported

    Ultimate Powerbox fully supports INDI.

    External brackets support Losmandy / Vixen Plate attachment

    Available is the optional pair of brackets to mount 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. The LED is very dim but in case you don’t like it on you can switch it off via the software.

    Power Cables are included in the package

    Four power cable of DC 2.1mm to 2.1mm male (1m) are included in the package.

    External Environmental Sensor

    External one (1) meter 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 persistence 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.

    USB2 Connectivity

    Controller is always connected to the USB Hub (7th internal USB port). No extra cable needed. Just connect the USB Hub to your laptop and you are done.

    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!


    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 firmware upgradable to support future features and bug fixes.

    Compact Size and Lightweight

    A blue anodized aluminium compact sized box enclose the controller board. Size is 12cm x 10cm x 3cm (4.72 inch x 4.06 inch x 1.2 inch). Weight is 400 grams (14.1 ounces).
