The differences with the 1100W model are minimal because the 1300W unit can only deliver full power with 230VAC input. The heatsinks are large to dissipate heat effectively, and the main transformer is small, thanks to its unique design. The build quality is high, and top-notch parts are used, including Infineon FETs and Japanese caps, by TDK, Rubycon, and Chemi-Con. On the primary side, we meet a full-bridge topology able to handle the unit’s full power without any dramatic effects. An LLC resonant converter is also used to boost efficiency. On the secondary side, we find synchronous rectification for 12V and a pair of DC-DC converters for the minor rails.
