Ultimate Powerbox

If you are tired of carrying multiple power packs and dealing with a mess of power and data cables, our Ultimate Powerbox, a sophisticated power control unit, is the absolute solution. Our 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 main power cord and one USB data cord comes to the Ultimate Powerbox from which branch off the other cables powering all devices.

The Ultimate Powerbox provides:

  • 4 x 12V Smart Outputs,
  • 2 x PWM duty cycle channels for your Dew Heaters or Flatbox
  • a USB2 High Speed Industrial Powered Hub with 6 available ports
  • a Unipolar Stepper Motor Controller
  • Environmental & Power sensors
  • In a compact size with lots of features!

We strongly believe that if you own a remote observatory or you do advanced imaging you are gonna love this device!




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 stand 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. Each output has overcurrent /short circuit and overvoltage protection.

More than 20A of total power

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

Stand Alone Software

Our modern 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.

Ultimate Powerbox Software

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.

Stepper Motor Controller

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

Ultimate Powerbox Software

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 tune 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
  • Pass environmental settings to supported software (such as Sequence Generator Pro)
  • Switch ON or OFF all 12V outputs.

Ultimate Powerbox ASCOM Environment

External brackets support Losmandy / Vixen Plate attachment

We provide an optional bracket to attach the Ultimate Powerbox to a Losmandy or vixen plate. The bracket can be screwed on the top of the device 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. Our led is very dim but in case you don’t like the brightness you can switch it off via the software.

All Power Cables are included

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

Ultimate Powerbox

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.

USB2 Connectivity

Controller is always connected to the USB Hub (7th 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!

Watchdog Feature

A sophisticated watchdog resets the device if for any reason there is no response from the controller for two (2) seconds. A neat feature in the unlikely event of the microcontroller freeze – when have a remote observatory and you need to be sure that everything works as expected.

Upgradable Firmware

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

Compact Size and Lightweight

A blue anodised aluminium compact sized box enclose the controller board. Size is 13cm x 10cm x 10cm. Weight is 400 grams.

Bundle your favourite computer with our Ultimate Powerbox

We don’t follow the idea to embed a computer in the UPB device. Our concept is to keep separately the power / environmental / stepper control and the PC hardware. After a year the PC specifications will be obsolete. Spend the extra money on a separate computer which you can upgrade after some time. Choose a “compute pc stick” or a “computer cube” that fits your needs and bundle it with our Ultimate Powerbox. Check the following image of what we have done in our roll off observatory.

Q: What kind of power supply do I need?

A:  We suggest to buy a good linear 12V / 10-20A branded power supply. Cheap units cause voltage drops on high load and ripple effect. This will cause issues and artefacts to your precious CCD Camera.

Q: What type of cable do I need to use for input?

A: If you are going to make a custom input cable notice that you need at least a AWG 18 cable. Make also sure that you do not exceed 3-4m to to reduce voltage drops.

Q: I would like to use the Ultimate Powerbox to my remote observatory. What if the device freezes for some reason?

A: We have good news for you. The device has a hardware watchdog and resets itself if the microcontroller is not responsive after 2 seconds.

Q: My observatory is in a very cold place. Is there any issue with the electronics of the device?

A: All electronic components were selected to support temperature ranges from -40 to +80 °C. Moreover USB2 Hub Chip is an industrial model which fully complies with this temperature range.

Q: I have a new feature request. Is it possible to implement it in the software / firmware.

A: Sure, we are here to listen our customers. Please contact us and tell us your idea!

Q: What if I accidentally short-circuit an output?

A: Ultimate Powerbox has an internal protection for all outputs. In less that 5 milisecs it will cut off the power of this output and a warning message will be appeared at the software screen.

Q: What if I accidentally reverse polarity?

A: Ultimate Powerbox has an input reverse polarity protection. Device will not power on and of course will not allow any voltage to leak to outputs.

Q: What if I short-circuit a USB Hub port?

A: Device has a USB short-circuit / overcurrent protection per port. It will instantly isolate/disable the selected USB port. Just remove the USB device and plug another one to bring it to life.

Q: I have a USB device which requires more power than a normal USB port.

A: No problem. The 6th port of the USB hub can support up to 3Amps of current. Plug it there and it will do the job.

Q: At the middle of the night humidity rises up. What can I do for my optics?

A: Enable auto-dew functionality. Device firmware will adjust the power of both Dew Heater outputs consulting the humidity / dew point levels that environmental sensor reports.

Q: Can I upgrade the firmware?

A: Of course, device was designed to support firmware upgrade for future features or bug fixes.

Q: Why you don’t place a mini PC inside the powerbox?

A: We really don’t support this idea. Why to buy something and pay noticeable amount of money for a mini PC that will be obsolete (in its specification) after 6-12 months? We suggest you to just get a compute stick, plug it in the 6th USB hub port to supply it with enough power juice and you have your tiny PC up and running! If you don’t like it after some time, buy another one with higher specs and lower price for sure! Check the user shots for an example of this approach!
