Hi folks! does this unit need a transformer and a rectifying diode bridge. if so, can anyone recommend which diodes i need? i am a beginner, thanks.

Question

Accepted Answer

It requires a Direct Current input - typically from a battery - and can either "boost" or lower the voltage to the output.  A common use would be to supply a constant 12 Volts output from a "12 Volt" (Car) Lead Acid battery that can actually have a fully charged voltage of around 14 Volts, dropping to under 11 Volts when nearly discharged.  Another use is to "boost" the Voltage at the output - the same 12 Volt Lead Acid Battery could be used to boost the Voltage to, say, 24 Volts.  Yes, you could use a transformer and rectifier diodes, plus regulator/smoothing components to create the DC Input Voltage from the Mains Power (120/240 Volt AC) - but what would be the point?  You might just as well buy a Mains AC to variable DC Output Power Supply in the first place.  I hope that helps!
