The company focuses on converting utility-grade AC power into various DC voltages required by high-availability infrastructure. Its core product lines include AC/DC power supplies, DC/DC converters, and renewable energy inverters. Specific series such as the 'Novum' digital point-of-load converters, high-efficiency rectifiers like the 'SCP' series, and solar inverters including the 'Trio' and 'Uno' families showcase its technological breadth.
