Choosing a suitable power supply

LED’s are DC (direct current) devices – you can’t run them off the mains which is a high voltage AC (alternating current) supply. To convert and condition this 230V mains you need a power supply unit or PSU, but this is commonly called a ‘transformer

DC wiring from the power supply to the LED’s

Remember that the power coming out the DC end of the PSU although at a lower voltage  will now be at a considerably higher current: eg for a 300W 230V input 5V output supply, the mains input current is 300/230 = 1.3A, but the output DC current is 300
