Power Management
Power management here covers the supplies that drive low-voltage AV and lighting from a tidy, reliable source, turning mains power into the DC voltage and current a piece of kit needs. Choosing the right unit comes down to matching the output voltage and the current rating to the equipment you are running.
At the compact end there are switch-mode power supplies with selectable 3 to 12V DC output, supplied with a set of adaptor plugs so a single unit can power a range of small devices. These span outputs such as 600mA, 1000mA, 1500mA and 2250mA, covering everyday low-current jobs where you want one flexible supply rather than several fixed ones. The adaptor plugs let you change the connector to suit different devices.
For lighting, there are fixed 12V DC LED drivers rated from 2A through to 5A, supplied for indoor use with a short hard-wired lead. These give a steady 12V feed for LED strips and similar fittings, with the current rating setting how much lighting a single driver can carry. Stepping up in power, the range also includes higher-current 13.8V switch-mode supplies, from smaller units up to high-output models reaching 600W, including multi-channel versions, for heavier loads where more current is needed.
Whether you are powering a single LED strip, a small stack of devices or a fuller setup, the spread of voltages and current ratings means you can pick a supply sized to the job rather than over- or under-specifying it. Free UK delivery over £99, with worldwide shipping available.
