The ZWO 12V 10A AC to DC Power Adapter is the central power solution for the dedicated astrophotographer, engineered to eliminate the voltage sag and cable complexity that comes from running multiple devices on underpowered supplies. It provides a single, robust, and reliable source of 120 watts, ensuring every component in your imaging train receives stable, continuous power from dusk until dawn.
In astrophotography, consistent voltage is not a luxury, it is a prerequisite for clean data. Fluctuations can cause mount tracking errors, inconsistent TEC cooling temperatures, and unpredictable behavior from focusers and filter wheels. This adapter is designed to provide the stable electrical foundation your entire system needs to perform as designed.
With a full 10A (120W) of available current, this adapter is built to run a complete, modern imaging rig without compromise. It delivers enough power to simultaneously run a power-hungry cooled CMOS camera, a harmonic or equatorial mount, an ASIAIR controller, an electronic focuser, and a filter wheel, all from one outlet. This consolidation prevents the voltage drops that occur when a lesser supply is stretched to its limit, which is a primary cause of intermittent hardware failures during a long session.
At the core of the adapter is a switch-mode power supply that delivers a tightly regulated 12V DC output. This stability is critical for sensitive components. For your camera's thermoelectric cooler, it means holding a setpoint temperature to within a fraction of a degree all night, resulting in cleaner calibration frames and lower-noise final images. For your mount, it ensures the motors receive the consistent voltage needed for precise, uninterrupted tracking.
This power supply is equipped with essential internal safety circuits, including over-current, over-voltage, and short-circuit protection. These features act as a firewall, protecting your thousands of dollars of connected astronomy equipment from unpredictable power surges or accidental shorts. In the event of an electrical fault, the adapter is designed to shut down safely, preventing catastrophic damage to your camera, mount, or computer.
The adapter terminates in a 5.5mm x 2.1mm center-positive barrel connector, the de-facto standard for ZWO products and a wide range of other astronomy gear. This ensures out-of-the-box compatibility with ASIAIR controllers, AM series mounts, and all ZWO cooled cameras, eliminating the need for custom cables or intermediate adapters. Its universal 100-240V AC input means you can use it anywhere in the world with a simple plug adapter, making it a reliable travel companion for workshops and star parties.
The two-piece design, featuring the main power brick and a separate AC power cord, makes for easier storage and cable routing. You can leave the main brick attached to your rig and only disconnect the wall-side cord, simplifying setup and teardown. This modularity also allows you to easily swap the AC cord for one with a different plug type when traveling internationally.
The AC portion of the cable (from the wall connector to the power brick) is approximatively 178cm. The DC portion of the cable (from the power brick to the 2.1 x 5.5mm connector) is approximatively 122cm.
The primary trade-off for this level of power is physical size. The 10A adapter is larger and heavier than the 5A models often included with individual cameras. This is not a limitation but a necessary consequence of its high-wattage design. For imagers running a single cooled camera, a smaller supply may be sufficient, but for those running a complete, multi-component system, the capacity and stability of this 120W unit is the correct and more reliable choice.
If you are powering a full imaging rig including a cooled camera, a mount like the AM5, an ASIAIR, and other accessories, the 10A adapter is recommended to prevent voltage drops. For powering only a single cooled camera and one or two small accessories, a 5A supply is often sufficient.
Yes. The 10A (120W) capacity is specifically designed to handle the power requirements of a ZWO mount (like the AM5 or AM7), an ASIAIR, a main cooled camera, and several other devices simultaneously through the ASIAIR's power distribution ports.
Yes, but only if there is a wall outlet providing 100-240V AC on your battery.
It uses a standard 5.5mm x 2.1mm DC barrel connector with a center-positive polarity. This is the standard connector for virtually all ZWO products that require 12V power, ensuring wide compatibility.
