Pegasus Ultimate Powerbox F.A.Q:
Q: What kind of power supply do I need?
A:  We suggest to buy a good linear 12V-13.8V / 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. You can also use a Lead Acid battery (12V-13.8V).

Q: What type of cable do I need to use for input?
A: If you are going to make a custom input cable please note that you need at least a AWG 17 cable. Make also sure that you do not exceed 2 meters (6.5 feet) to to reduce voltage drops.

Q: I would like to use the Ultimate Powerbox into 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 controller 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 USB3.1 Hub controller is an industrial grade 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 about 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 input 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 replug it to bring it to life.

Q: I have a USB device which requires more power than a normal USB port.
A: Each USB port provides 2.5Amps of current. You will be fine.

If you use an Intel M3/5 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. 
Q: In 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 has been designed to support firmware upgrade for future features or bug fixes. Software will prompt you for a firmware upgrade, if there is a need.

Q: Why dont you place a mini PC inside the Ultimate Powerbox?
A: We really dont 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 dont 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!

Q: Does it support INDI
A: Yes 100%. There are two implementations. Indigo and native INDILib. Both support Windows/OSX/Linux.
