Default Dual Power Supply.l

Hi.

I am building a Class D power amp (Magnatec SDV1042-300). This one "only" needs +60V and Gnd (not -60V like most class A/AB). The transformer I have for this has "of cause" 2 sec. outputs, will it be possible to make the power supply dual (2 x +60V and GND) and connect both to the module (like the picture). I am thinking of doing this to get "2 time"s the power (VA) from the transformer since only connecting one winding is to low power for the module.

Michael

Yes. You can also parallel the secondaries before rectification and smoothing. That could reduce the parts count.
