The FAST-Bi-1K5 series is a modern generation of bipolar, bidirectional and regenerative 4-quadrant power supplies for demanding laboratory, industrial and research applications. It enables not only the precise injection of energy, but also the safe feeding of excess energy back into the grid – ideal for dynamic loads and cyclic testing processes.
General features of the FAST-Bi-1K5 series
- Full 4-quadrant operation (bipolar, regenerative, bidirectional)
- Control modes: Constant Current (CC), Constant Voltage (CV), Constant Power (CP) and Constant Resistance (CR)
- Digital control with configurable control loop and PID auto-tuning for optimal adaptation to any load
- High precision: <0.01% output accuracy, <0.0002%/K temperature drift, < 0.001% long-term stability (8 h)
- Fast dynamics: Rise time <70 µs, closed-loop bandwidth 5 kHz
- Integrated waveform generator (100 kHz) and 4-channel oscilloscope via web GUI
- Communication: 10/100/1000 Mbit Ethernet (TCP-IP/UDP) and 2× SFP+
- Embedded web server & EPICS IOC 19”-2U Stand-alone Device with Local Display and Controls Parallel Connection of up to 4 Devices (max. 6 kW) Extensive Internal and External Protection and Interlock Functions Typical Applications Battery Testing (Regenerative Charge/Discharge Cycles) Superconducting Magnets and Magnet Power Supplies PV Cell and Module Testing Configurable Electronic Load (Active Load) Research Facilities and High-End Industrial Applications />
Variant FB1K5150010X – FAST-Bi-1K5 150-10
The FB1K5150010X variant is the highest current version within the FAST-Bi-1K5 series and delivers ±150 A at ±10 V at a rated power of 1,500 W. It is particularly suitable for applications with very low impedance and high current requirements.
Comparison with other variants in the series
While all models offer the same core functions (4-quadrant operation, control modes, interfaces, protection functions), they differ in current/voltage range and, in some cases, in rated power:
- FB1K5150010X (150-10): ±150 A / ±10 V – maximum current at low voltage FB1K5100020X (100-20): ±100 A / ±20 V – balanced current-to-voltage ratio FB1K5050040X (50-40): ±50 A / ±40 V – medium voltage range FB1K5030050X (30-50): ±30 A / ±50 V – higher voltage at reduced current FB1K5020100X (20-100): ±20 A / ±100 V – highest voltage and 2,000 W Rated Power
Product Features:
