SP&S has specialized in the R&D and manufacturing of linear power supplies and amplifiers for over 50 years. Its expertise is widely applied in electrical EMC testing and grid-connected PV inverter validation, complying with stringent standards including IEC 61000, IEC 60555, IEC 50530, and IEC 62116. By integrating SP&S's amplifier technology with its extensive HIL system development experience, KeLiang developed the PHIL (Power Hardware-in-the-Loop) test system. This system extends signal-level real-time simulation to power-level testing, serving as a key tool for R&D in distributed energy systems and electrical equipment validation.
