Another category is Programmable AC Test Power Supplies, supporting both single and three-phase output with advanced functions like harmonic simulation. High-end models support multi-mode output (AC/DC/AC+DC) and wide frequency ranges, suitable for R&D and global power simulation.

TFS-A Series : is a flexible AC power supply designed for phase conversion (e.g., single-phase input to three-phase output), suitable for testing applications requiring versatile power simulation in small to medium capacities.

TFP-A Series : stands out with its ability to simulate harmonic distortion, allowing testing under real-world non-ideal power conditions. Unlike standard models that output pure sine waves, the TFP-A can generate distorted waveforms to evaluate product reliability and performance more realistically.

TFB-1000/P & TFB-3000 Series : This series power supplies can output the voltage of power grids in various countries around the world and simulate the normal and abnormal conditions of power grids in various countries according to relevant standards and regulations.
