iOptron AC Adaptor, 1.5A
- 1.5A Current Output
This AC Adapter provides a regulated 1.5A current, designed to safely power specific astronomy mounts and accessories with modest energy requirements. It serves as a fundamental component for running equipment from a standard wall outlet, eliminating the need for portable battery packs during backyard observing sessions.
A stable power source is critical for the proper function of electronic astronomy equipment. This adapter is rated for a 1.5A (ampere) load, making it suitable for many popular star trackers, smaller GoTo mounts running tracking motors without heavy slewing, or single, low-draw accessories like a basic dew heater strip. Using an adapter with the correct amperage prevents voltage drops that can cause tracking errors or electronic resets. Before use, always confirm the power requirements (voltage and amperage) of your specific device to ensure compatibility.
A 1.5A adapter is generally sufficient for powering lower-demand devices. This includes most portable star trackers, the tracking motors on smaller equatorial mounts (when not slewing at high speed), and some standalone accessories like electronic filter wheels or a single, small dew heater strip.
It depends on the operation. While 1.5A might be enough to run the tracking motors on a NexStar 6SE for visual observation, it may be insufficient for high-speed GoTo slewing, which can cause a current spike. Many mid-sized GoTo mounts recommend a power supply of 2.5A or more to handle peak loads without issue. Always check your mount's specific power requirements in its manual.
You will need a higher amperage power supply if you are running multiple devices or a single device with a high power draw. Common scenarios include:
No. Cooled astronomy cameras, such as those from ZWO or QHY, require significantly more current to run their thermoelectric cooling (TEC) systems, often in the range of 3A to 5A. A 1.5A adapter is insufficient and will not allow the camera's cooler to function correctly.
Using an underpowered adapter can lead to intermittent equipment failure and poor results. When a device like a mount tries to draw more current than the adapter can supply, the voltage drops. This can cause the mount's computer to reset, ruin a long exposure by causing a tracking error, or even lead to the adapter overheating and failing.
Possibly, but it would be at the limit. A Sky-Watcher Star Adventurer has a very low power draw for tracking. However, even a small dew heater strip can draw close to 1A on its own. Combining the two could exceed the 1.5A rating, especially if the dew heater is set to a high level. It is safer to use a power supply with a higher rating (e.g., 2.5A or more) if you plan to run accessories alongside your mount.
