What is the key for the colour coding of the tips?

Asked by: Stephen
There is no key. You would select the tip that fits your device, choose the correct voltage and most important of all check that you have set the TIP POLARITY correctly. FAILURE TO SET CORRECT TIP POLARITY WILL DESTROY YOUR ITEM.

Is this unit regulated and is it centre positive? Although it states 27watts any ideas on the actual current at each voltage?

Asked by: SANJ3D
Contacted Maplins on-line/live customer support who were able to help. Confirmed the unit is regulated (all Maplins Power supply adapters are). The Unit can provide up to 2.25amps at each voltage.
