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.

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

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 3Amps of current is available. You can tune the output from 3 Volt to 12Volt and save this setting in controller’s memory. Every time UPBv2 boots the port will be tuned to the stored voltage setting,

Always ON – 12V Output

One unregulated 12V output can provide up to 8Amps. So, In addition with the Smart 4 x 12V outputs you have one more to connect additional equipment. This 12V 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 controller by the “Auto Dew” function.

Does the Powerbox work as a battery pack

No, Powerbox relays and distributes power from an external power source. It does not have batteries inside so it cannot store energy.

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

UPBv1: 6th USB port deliver up to 3Amps of current

UPBv2: Each USB port provides up to 2.5Amps of current.

Powerbox Advance: First USB3 native port can deliver up to 3Amps. All other USB3 ports deliver up to 900mA

Is there a comparison page between Powerbox products?

Please check the Powerbox comparison table at the bottom of this page

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

All electronic components are selected to support temperature ranges from -40 to +80 °C. Moreover, UPBv2 USB3.1 Hub controller is an industrial grade model which fully complies with this temperature range.

What if I accidentally reverse input polarity?

All of our Powerbox products have an input reverse polarity protection. Device will not power on and of course will not allow any voltage to leak to outputs.

What if I accidentally short-circuit an output?

All Powerbox products have an internal protection for their 12V outputs. In less that 5 milliseconds controller will cut off the power of the output and a warning message will be appeared on the software.

What if I short-circuit a USB hub port?

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 re-plug it to bring it to life.

What kind of power supply do I need?

We strongly suggest to use our certified 12V/10A sealed type power supply unit.. Cheap PSU might cause voltage drops on high load and introduce ripple effect. This will cause issues and artefacts to your precious CCD Camera.
A battery (deep cycle type is suggested) is also an option but you will have to calculate your average load and the time you can use the battery.

Why don’t you place a mini PC inside the Ultimate / Advance Powerbox?

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 (for its specification) after 6-12 months? We strongly suggest to just get a mini factor PC (E.g Intel NUC), plug it on a 12V output and use it as your astro-computer.! 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!
