Our 30VA Audio Grade transformers with secondaries of 4,2 for use with our HPULN power supplies. With this transformer an output voltage of 3,3V is feasible after the HPULN power supply. This configuration can typically be used to power DAC's and other IC's or circuits with a voltage need of 3,3VDC.


For a nice look the transformer has an internal threaded sleeve of M6 size and a closed top.
Unlike commercial power line transformers, the AUDIO GRADE version is covered with a black Mylar tape which gives it an aesthetic appearance. The epoxy filled center with an opening for the M6 screw eliminates a need for an additional mounting bracket. The neoprene gum pad affixed to the bottom successfully eliminates transmission of vibrations.The entire construction utilizes high-class, laboratory-tested parts. The core and the windings are impregnated, and the production process is being scrupulously controlled at every step.
