Desktop power supplies are often also known as lump-in-line, especially if they have a fixed input and output lead. Most of our units have either a standard 3 pin IEC (kettle type) input lead or a 2 pin figure of 8 input. If you are looking for a replacement we would need to know:

  1. The voltage of the unit which you are replacing, this is very important because if you try and power your device with the wrong voltage then you could damage it. The voltage should be marked on the failed power supply, or if you have lost that then should be on the device you are powering.
  2. The current or power is also important but does not need to be exactly matched. As long as the current (in Amps or A) is higher than the device requires then it will run fine and there is no risk of damaging it. i.e. if your device requires 12Vdc 1.5A then a 12Vdc 2A power supply will be fine
  3. The output jack size is also very important too. There are two common sizes which are 2.1mm and 2.5mm and this size refers to the internal diameter of the jack. It is very difficult to tell between the sizes and therefore we suggest you purchase an adapter for the jack which changes a 2.1mm to a 2.5mm jack which means you have both possibilities covered (2.1mm to 2.5mm)
