Click to expand... hi, If its 240V AC as you say, then you could buy a 240Vac to 12Vac transformer and add a rectifier, capacitor and 7809 regulator to give 9V DC. Is this what you are asking for.?

J JeanTech Member Apr 12, 2010 #6 Hi Louis Have a look at this variable power supply circuit. You can adjust the output to up to 24V. It can source up to 5A current. Power Supply
