Player One 12V 5A Power Supply (DC5.5 x 2.1mm)

Product Overview

The Player One 12V 5A power supply delivers regulated DC power to Player One cooled astronomy cameras and to the Active Cooling System (ACS). It outputs 12 volts at up to 5 amps through a DC5.5 × 2.1 mm barrel connector — the standard input used across the Player One cooled range — giving the thermoelectric cooler the steady current it needs to hold a set temperature.

Who It's For

This is for you if you run a Player One cooled camera (Ares, Artemis, Poseidon, Uranus PRO, Apollo PRO, ZEUS series) or the ACS module and want a correctly rated mains adapter to power the cooler. If you image from an observatory or a fixed pier on mains power, this is the plug-in supply for the job; battery/field power is a separate setup.

Key Features & Design

• 12 V / 5 A regulated output: supplies the current a two-stage TEC cooler draws when pulling well below ambient.
• DC5.5 × 2.1 mm barrel plug: matches the power input on Player One cooled cameras and the ACS.
• Four regional plug standards: choose US, Europe, UK, or China at checkout so the wall plug fits your outlets.

Recommended Uses

Powering the cooler on a Player One cooled camera during deep-sky imaging sessions, and powering the Active Cooling System (ACS) on an otherwise uncooled camera, wherever mains power is available.

Compatibility and Accessory Notes

Use it with any Player One device that takes 12 V through a DC5.5 × 2.1 mm centre-positive barrel jack — the cooled camera range and the ACS. The camera's data connection (USB) is separate; this supply powers the cooling only. If you are not sure your device uses this jack, send us your model and we will confirm it before you order.

Good to Know Before You Order

• Powers cooling, not data: the camera still connects to your computer over USB; this adapter drives the TEC cooler and fan.
• Pick your region: the US, Europe, UK, and China options differ only in the wall-plug standard — the 12 V / 5 A output is the same on all four.
• Mains supply: this is an AC wall adapter. For field use away from mains you would power the camera from a 12 V battery instead.

Frequently Asked Questions

Is it difficult to set up?

No — select your region's plug, connect the barrel jack to the camera or ACS power port, and plug it into the wall. There is nothing to configure.

Which region should I choose?

Choose the plug standard that matches your wall outlets: US, Europe, UK, or China. The DC output is identical across all four.

Will it power my Player One cooled camera?

Yes, if the camera uses the 12 V DC5.5 × 2.1 mm input, which the Player One cooled range and the ACS do. Send us your model if you would like us to confirm.

Bottom Line

A correctly rated 12 V / 5 A mains adapter for Player One cooled cameras and the ACS, with a DC5.5 × 2.1 mm plug and your choice of US, Europe, UK, or China wall standard.
