Replacement 12V DC power supplies from Transcension in 500mA, 1A and 2A ratings, the universal versions taking 100-240V 50/60Hz input with interchangeable UK, EU, US and Australian AC pins, so one unit covers a whole touring itinerary. These are the standard replacement supplies for Transcension DMX controllers and similar low-power kit, with a 2.1mm centre-positive DC barrel plug on the 500mA universal model.

Matching a replacement PSU is a three-step check. Voltage must be exact, 12V here, since over-voltage kills equipment and under-voltage causes the kind of intermittent behaviour that is miserable to diagnose. Current rating should meet or exceed what the device draws, and a higher-rated supply is always safe where a lower-rated one is not. Then confirm connector size and polarity against the device’s markings before powering up.
