The Keysight N7977A Advanced Power System is a 2U rack-mount dynamic DC power supply engineered for automated test equipment (ATE) applications requiring high-speed dynamic sourcing and measurement. It delivers 160 V, 12.5 A, and 2000 W of continuous power with command processing under 2 ms and up/down programming speeds to 500 µs—enabling test throughput up to 100 times faster than conventional supplies.
Technical Specifications
• Output Power: 160 V, 12.5 A, 2000 W (2 kW) single output
• Input Supply: 100/240 VAC, single phase, 40 A maximum nominal
• Voltage Accuracy: ±62 mV (programming and measurement)
• Output Noise & Ripple: 30 mVpp
• Response Time: 0.5 ms
• Command Processing: <2 ms
• Up/Down Programming Speed: Up to 500 µs
• Dimensions: 1.75 in H × 16.81 in W × 22.39 in L (2U rack mount)
– Key Features
• Dynamic Sourcing & Measurement: Dual voltage and current measurement with DMM-level accuracy; power, peak power, watt-hour, and amp-hour measurements included.
• Arbitrary Waveform Generation: Supported with adjustable slew rate control.
• Two-Quadrant Operation: Continuous smooth transitions between positive and negative current with programmable limits and automatic down-programming. Standalone unit provides 10% rated current two-quadrant capability; full two-quadrant operation requires N7909A power dissipater unit(s) to sink rated power.
• Parallel Configuration: Built-in APS paralleling supports up to 10 kW with automatic equal current sharing via three-wire rear-panel connection and mode enforcement (CV/CC).
• Adjustable Measurement Rate: Balances speed versus accuracy based on test requirements.
– Typical Applications
• High-speed dynamic battery and power cell testing
• Power storage device characterization
• Transient load simulation and response validation
• Rapid device power cycling and threshold testing
– Compatibility & Integration
• Interfaces: GPIB, USB, LAN (LXI-Core)
• Optional Accessory: N7908A Black Box Recorder for measurement data logging and trigger event tracking
