The FAST-Bi-1K5 series comprises high-precision, digital 4-quadrant power supplies with bipolar, bidirectional, and regenerative functionality. They enable controlled energy input and output in all four quadrants and efficiently feed excess energy back into the grid. This makes them ideal for dynamic testing tasks in research, development, and industry.
