Based on the 5kV/20pF isolated TDK-Lamba PXG-M15 15W DC-DC module series, this board takes an input of 40-60V and converts it to a 15W, 5V/12V/15V regulated output. The voltage depends on 3 of the components loaded to the PCB (i.e. pre-selected). The outputs are regulated by 5 parallel LT3045 ultra-low noise linear regulators. These can be connected in either series or parallel.
