Pegasus Pocket Powerbox Micro

Pocket Powerbox Micro
This small-sized device (in short PPB Micro) is suitable for the “grab and go” astrophotographer. It can provide up to 10Amps of power and has a sufficient number (4) of 12V Outputs, Two Dew Heater Channels, an adjustable voltage power output, and an environmental sensor to monitor humidity/temperature (dew point).

Pocket Powerbox Micro is the successor of the Pocket Powerbox

Pegasus Pocket Powerbox Micro Main Features:

4 x 12V DC Power outlets for your equipment (ON/OFF via software)

  • 10 Amps of total power
  • A Voltage Adjustable Output (Can be switched ON/OFF – 3V, 5V, 8V, 9V, 12V)
  • 2 Channels PWM Dew Heaters – RCA Outputs (Adjust levels via software)
  • Humidity and Temperature Sensor (included)
  • Auto Tune Dew Heaters (Auto-Dew)
  • Reverse Polarity Protection / Overvoltage Protection
  • USB / PC Controlled or Standalone Operation out of the box
  • Lightweight and extremely compact CNC aluminium enclosure

4 x 12V DC Power outlets

A powerful mosfet transistor provides “electric juice” to your precious equipment. It supply of electricity 4 outputs. Can switch ON/OFF all four ports (* together – single channel).

Built in Voltmeter

A precise voltmeter measures and displays in real time your input voltage. If the input is more than 14.5V, the power is instantly cut off to protect your equipment from overvoltage.

Adjustable Regulated Output

An adjustable output is suitable to provide power to your DSLR / Mirrorless camera / or your RPI3/4. You can tune the voltage to different levels (3,5,7,8,9,12 Volts). Please note that we provide a wide range of battery couplers for Canon, Nikon, Sony, FUJI DSLR and Mirrorless Cameras

Expansion Port (EXT)

EXT (expansion) port is available for device expansion. This RJ12 socket allows the connectivity of current and future Pegasus Astro products. Plugged devices can be controlled from Pocket Powerbox Unity Platform or a dedicated ASCOM driver.

The device supports the eXternal Motor Controller

Built in Amp-meter

An Amp-meter which is installed right after the DC input, reports the total electric current.

Moreover, there are three additional amp-meters: One for the 12V quad outputs and two for the Dew Heater Channels. This allows you to easily monitor the detailed and overall power consumption of your equipment.

Standalone Operation “out of the box”

Pocket Powerbox Micro can work “out of the box” as a standalone device. Just plug the cables, setup the “autodew” functionality and every time you boot the device, it will retrieve your settings. So, If you don’t like to connect to a PC every time, you don’t have to. Simple as that!

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)

The controller can auto adjust the heater power levels by consulting the environmental sensor Dew Point reading. Just click “Auto” and leave to Pocket Powerbox Micro to decide if it is time to turn on and precise tune the level of your dew heaters.

More than 10A of total power

The powerbox has been designed to support up to 10 Amps of total current.

Led Indications for power and failure states

Led can blink in patterns to warn you about important power issues (e.g over or under voltage). Also, light can be turned off by using the software. Our LED is very dim but in case you don’t like it on you can switch it off

Reverse Polarity Protection

Pocket Powerbox Micro 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

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.


Pocket 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:

Pass environmental settings to supported software (e.g Sequence Generator Pro / MaximDL ) (ASCOM ObservingConditions)
Switch ON or OFF all 12V outputs. (ASCOM Switches)


Pocket powerbox fully supports INDI, Bundle it with Stellarmate or any other device that can use INDILib.

Unity Platform Support

Pegasus Astro Unity Platform is our new all around application. Our goal is to provide a robust and modern application that is going to support current and future products under one roof.
A modern frontend allows the full control of all Pegasus Astro devices.
Moreover, a REST JSON api helps developers from 3rd party software to interact with our products.
As we continuously develop our applications, based on customer feedback, lots of innovative features are going to be added in upcoming releases.
