  • 12V/7A power supply + 4-way cable

    This stabilized 12V power supply delivers a robust 7A of current, capable of powering your entire imaging rig from a single outlet. The included 4-way splitter cable features two 5.5/2.5mm connectors and two 5.5/2.1mm connectors to accommodate a mix of astronomical devices. This unit is designed for use with 220V power systems and is not compatible with standard 110V/120V outlets in North America.

    A Centralized 7A Hub for Your Entire Imaging Rig

    Managing power cables at the telescope can lead to snags and tracking errors. This 12V/7A power supply consolidates your power needs, eliminating the need for multiple adapters. The stabilized 7A output provides ample current to run a cooled CMOS camera, a mount, a calibration module, and other accessories simultaneously, ensuring consistent voltage for reliable operation.

    4-Way Cable with 2 Connector Sizes & 220V Input

    The integrated 4-way splitter cable addresses the varied power inputs of modern astro-gear. It provides two 5.5/2.5mm barrel connectors, often used for hardware like calibration modules, and two 5.5/2.1mm connectors, the standard for most astronomy cameras and filter wheels. This configuration allows you to directly power a diverse set of equipment without needing extra adapters.

    • Critical Compatibility Note: This power supply is built exclusively for 220V electrical grids common in Europe and other regions. It cannot be used with 110V/120V systems without a step-up transformer.

  • What is the main benefit of this 12V/7A power supply?

    The primary benefit is cable consolidation. It allows you to power up to four separate devices from a single wall outlet, dramatically reducing the number of power bricks and cables around your telescope mount. This simplifies your setup and minimizes the risk of cable snags during an imaging session.

    Can I use this 12V/7A power supply in the United States or Canada?

    No, not directly. This power supply is designed for 220V input only. Standard outlets in North America provide 110V/120V. Plugging this unit into a 110V/120V outlet will not work and could damage the supply. It is intended for regions with 220V electrical systems.

    What are the different connector sizes on the 4-way cable for?

    The cable includes two common barrel connector sizes to fit different astronomical equipment:

    • Two 5.5/2.5mm connectors: Often used for devices like spectrograph calibration modules or some focus motors.
    • Two 5.5/2.1mm connectors: The most common size, used by the vast majority of cooled astronomy cameras, filter wheels, and electronic focusers.

    Is the 7A output of this supply enough for a GoTo mount and a cooled camera?

    Yes, in most cases. A typical cooled CMOS camera might draw 2-3A with the cooler at full power, and a medium-sized GoTo mount might draw 1-2A while slewing. The 7A capacity provides a healthy margin to run both of these, plus other accessories like a dew heater or focuser, without overloading the supply.

    Why is a "stabilized" 12V power supply important for astrophotography?

    A stabilized power supply provides a consistent 12V output without voltage fluctuations. This is critical for sensitive electronics like camera sensors and mount controllers. Unstable power can introduce electronic noise into your images or cause erratic behavior in your mount's tracking.

    Could I power a Shelyak calibration module and a ZWO camera with this 12V/7A supply?

    Yes, this is an ideal use case. You can use one of the 5.5/2.5mm connectors for a Shelyak calibration module and one of the 5.5/2.1mm connectors for a ZWO or QHY camera, with two additional ports remaining for other devices like your mount or a filter wheel.
