The FAST-Bi-1K5 series comprises high-precision, digital 4-quadrant power supplies with bipolar, bidirectional, and regenerative functionality. They enable precise power input and output in all four quadrants and efficiently return excess energy to the grid. This makes them ideal for demanding testing, laboratory, and industrial applications with dynamic load profiles.
General Features of the Series
- Full 4-quadrant operation (bipolar, regenerative, bidirectional)
- Control modes: CC, CV, CP, and CR
- Digital, configurable control with PID auto-tuning
- High precision: < 0.01% Output Accuracy Temperature Stability: <0.0002%/K Long-term Stability (8 h): <0.001% Rapid Dynamics: Rise Time < 70 µs, 5 kHz closed-loop bandwidth, 100 kHz waveform generator and 4-channel oscilloscope integrated. Communication: 10/100/1000 Mbit Ethernet + 2× SFP+. 19”-2U stand-alone unit with local color display. Parallel connection of up to 4 units (max. 6 kW). Extensive internal protection and interlock functions. Typical applications: Battery testing and energy storage testing; magnetic power supplies and superconducting Magnets
- PV cell and module testing
- Configurable electronic load (active load)
- Research and high-end industrial applications
