  • Software Bisque TheSky Fusion 12V DC Power Supply Unit 21A Max

    The Software Bisque TheSky Fusion 12V DC Power Supply Unit delivers up to 21A of continuous current, providing a robust power source for fully-equipped imaging systems. This 2 lbs unit is the specified high-capacity option for TheSky Fusion, distinguishing itself from the 11.5A model by supporting rigs with significantly higher power requirements.

    Power Your Entire Imaging Rig: 252W (21A) Total Output

    This power supply is engineered to handle the combined load of a modern astrophotography setup running through TheSky Fusion. With a total output of 252 watts (21A at 12V), it provides ample current for a GoTo mount, a cooled CMOS or CCD camera, multiple dew heater straps, and other accessories without voltage drop.

    Choosing the Right Supply: 21A vs. the 11.5A Model

    Selecting the correct power supply requires calculating the total maximum power draw of your equipment. Sum the maximum amperage listed on each device you plan to connect to TheSky Fusion. If the total exceeds 138W (11.5A), this 21A model is the necessary choice.

    • 11.5A Model Supports: Systems with a total draw up to 138W.
    • 21A Model Supports: Systems with a total draw between 138W and 252W.
    • Example Calculation: A mount (2A), cooled camera (5A), and dew heater (3A) have a combined 10A (120W) draw. The 11.5A model is sufficient. If you add a second camera or larger dew straps, your needs will likely exceed 11.5A, requiring this 21A unit.

  • How do I know if I need the 21A TheSky Fusion Power Supply or the 11.5A model?

    You must calculate the total power budget for your imaging system. Check the manufacturer's specifications for every 12V device you will connect to TheSky Fusion (mount, camera, focuser, dew heaters) and add up their maximum amperage draw. If the total is less than 11.5A (138W), the 11.5A PSU is sufficient. If the total is between 11.5A and 21A (252W), you need this 21A model.

    My setup includes a Paramount MYT mount (2A), a cooled CMOS camera (5A), and two dew straps (3A total). Is the 21A TheSky Fusion PSU correct?

    No, for that specific setup, a smaller power supply would be more appropriate. Your total maximum draw is 2A + 5A + 3A = 10A (120W). This is well within the capacity of the 11.5A (138W) model. The 21A PSU would work, but it would be oversized for your needs unless you plan to add more high-draw equipment soon.

    What happens if my equipment draws more than 21A from TheSky Fusion Power Supply?

    TheSky Fusion system itself supports a maximum total wattage of 480W. If your equipment's power requirements exceed the 252W (21A) provided by this PSU, you will need to source a third-party 12V DC power supply rated for up to 40A to safely power your system.

    I plan to power a large mount and multiple cameras through TheSky Fusion at a remote observatory. Is this 21A PSU enough?

    It depends entirely on the specific components. A large observatory-class mount, multiple cooled cameras, and aggressive dew control can easily exceed 21A. You must perform the power budget calculation. For example, a Paramount ME II (3A), two cooled cameras (5A each), and multiple dew strips (5A) would total 18A, making this 21A PSU the correct choice.

    What are the physical dimensions of the 21A TheSky Fusion Power Supply?

    The unit measures 8 × 12 × 2 inches and weighs 2 lbs. Be sure to account for this size when planning your observatory or portable setup.

    Can I use the 21A TheSky Fusion Power Supply with other hardware?

    While it is a standard 12V DC power supply, it is specifically designed and warrantied for use with TheSky Fusion. Using it to power other devices directly is not its intended application and may not be supported.
