The FAST-Bi-1K5 series represents high-precision, bipolar 4-quadrant power supplies with bidirectional and regenerative functionality. It enables both precise power injection and controlled energy absorption, including feeding back into the grid – ideal for dynamic test and verification environments.
General features of the series
- 4-quadrant operation (bipolar, bidirectional, regenerative)
- Control modes: Constant Current (CC), Constant Voltage (CV), Constant Power (CP), Constant Resistance (CR)
- Digital, configurable control with PID auto-tuning
- Very high accuracy: < 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
- Integrated 100 kHz waveform generator and 4-channel oscilloscope via web GUI
- Communication: 10/100/1000 Mbit Ethernet (TCP-IP/UDP) + 2× SFP+
- 19”-2U stand-alone device with local display
- Parallel connection up to 4 devices (max. 6 kW)
- Extensive protection and interlock functions
Typical applications
- Battery testing (charge/discharge cycles with Energy recuperation)
- Superconducting magnets and magnetic power supplies
- PV cell and module testing
- Configurable electronic load (active load)
- Research and industrial applications with high dynamic requirements
