Pegasus Pocket Powerbox
Pocket Powerbox (in short PPB) is suitable for the “grab and go” astrophotographer who does not want too much automation. Device can provide 10Amps of power, a sufficient number of 12V Outputs, Two Dew Heater Channels, A DSLR power output and an environmental sensor to monitor humidity and temperature.
The Pocket Powerbox provides:
4 x 12V DC Power outlets for your equipment
A powerful mosfet transistor provides “electric juice” to your precious equipment. It supply of electricity 4 outputs. Can switch on/off for all ports.
10 Amps of total power
Controller has been designed to support up to 10 Amps of total current.
Built in Voltmeter
A precise voltmeter measures and displays in real time your input voltage. If the input is more than 14V, the power is instantly cut off to protect your equipment.
DSLR 8V Output
A 8Volt Output is suitable to provide power to your DSLR camera. We provide different battery couplers for Sony and Canon DSLR / Mirrorless Cameras. (Can be switched ON/OFF)
2 Channels PWM Dew Heaters – with Industry Standard RCA 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 Tune Dew Heaters
Firmware can auto adjust the PWM Outputs by consulting the environmental sensor Dew Point reading. Just click “Auto” and leave to Pocket Powerbox decide if it is time to switch on and precise tune your dew heaters.
Humidity and Temperature Sensor (included)
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.
Reverse Polarity Protection
Pocket Powerbox has been designed with reverse voltage polarity protection. It will definitely save your night if you accidentally connect the main power supply the wrong way around!
USB / PC Controlled
Connect the device to your laptop/PC and control Pocket Powerbox from the supplied software or ASCOM drivers
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.
Device is firmware upgradable to support future features and bug fixes.

Q: What kind of power supply do I need?
A: We suggest to buy a good linear 12V / 10A 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 2m to to reduce voltage drops.
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.
Q: I have a new feature request. Is it possible to implement it in the software / firmware.
A: Sure, we are here to listen to our customers. Please contact us and tell us your idea!
Q: What if I accidentally reverse polarity?
A: Pocket 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: 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.
