If you’re going to use a connector-block, there’s a wide variety available, with varying numbers of outputs.

See the ‘power supply for two or more single-colour LED strips’ wiring diagram (fig 2) for more info. Then wire each LED strip starter-lead (+ve and -ve) to the connector-block’s output. The purpose of a connector-block is to let you split a single power supply across many outputs.Ĭonnect your transformer’s input terminals to the 240V mains supply (+ve and -ve cables), and its output terminals to the connector-block’s input. To connect multiple white / single-colour LED strips, you will need a connector-block, like the one shown, which you can obtain from any electrical supplier. If it’s powerful enough, then one LED transformer can be used to drive two (or three or even more) LED strips – as many as its output wattage allows.
