Good Day All.
I would like you advice on how I can go about using a power supply taken from a fruit machine.
The mains transformer has muliple inputs and outputs, but I am only intrested in the 240vac input and the 27vac output.
This power supply also has a small PCB with a BP35-02W Bridge Rectifier, a 4700uf 80wv Cap, and a 2.2kohm resistor across the power output.
As said the transformer is pushing out 27vac unloaded, and after the bridge rectifier, cap, and resistor it is pushing out 35 to 36volts dc unloaded.
The board that I need to connect this psu to can take upto 40volts, apart from two voltage regulators, L7812CV & L7805CV, and the L7800 range of voltage regulators has an absolute max working voltage of 35volts.
So with this in mind what is the best way to go about getting a stable 30 or 32volts dc from this but still being able to use the full power of the transformer in this case 10amps.
Thanks for your time.
Best Regards.
