1. An apparatus for converting power received from an input source for delivery to a load, comprising:a first printed circuit board (PCB) having one or more electrical terminations adapted for connection to the input source and one or more electrical terminations for connection to the load;
a power conversion module (PCM) having a module input and a module output, each being electrically connected to the first PCB, and power conversion circuitry adapted to convert power between the module input and the module output;
wherein at least one of the electrical connections from the module input or module output and the first PCB comprises a solder connection formed between a conductive area located on a vertical edge of the PCB and a conductive area located on a first vertical edge of the power conversion module,
wherein the vertical edges are approximately parallel to each other and the connection is located at an elevation below a top surface and above a bottom surface of the power conversion module.
